Considerations for Establishing Successful Coronavirus Disease Vaccination Programs in Africa

The accelerated development of coronavirus disease (COVID-19) candidate vaccines is intended to achieve worldwide immunity. Ensuring COVID-19 vaccination is crucial to stemming the pandemic, reclaiming everyday life, and helping restore economies. However, challenges exist to deploying these vaccines, especially in resource-limited sub-Saharan Africa. In this article, we highlight lessons learned from previous efforts to scale up vaccine distribution and offer considerations for policymakers and key stakeholders to use for successful COVID-19 vaccination rollout in Africa. These considerations range from improving weak infrastructure for managing data and identifying adverse events after immunization to considering financing options for overcoming the logistical challenges of vaccination campaigns and generating demand for vaccine uptake. In addition, providing COVID-19 vaccination can be used to promote the adoption of universal healthcare, especially in sub-Saharan Africa countries.     

The role of vaccines in COVID-19 control strategies in Singapore and China

ObjectivesIn this article, we critically review the development and implementation of COVID-19 vaccination in Singapore and China during the pandemic.MethodsWe collect and analyze data from a range of sources, including scholarly articles, statistics and documents from national governments in the two countries, and reports from international organizations.ResultsThere are important differences in the two countries’ approaches to the evolving pandemic, and thus the roles that COVID-19 vaccination plays in the overall response strategies in these two countries.ConclusionsWhereas Singapore adopted a “living with the virus” strategy, China continued to pursue a COVID-zero strategy. The overall COVID-19 response strategy of Singapore was largely shared by many countries in the world, while that of China was more unique and hardly imitated elsewhere. Nevertheless, vaccination played a significant role in both countries’ responses to the pandemic. A comparison and contrast between the vaccination processes in these two countries thus shed important light on the drivers and outcomes of COVID-19 vaccination in different settings.     

The COVID-19 pandemic in Greece,Iceland, New Zealand,and Singapore: Health policies and lessons learned

Objective(s)This paper aims at providing an overview of the COVID-19 situation, health policies, and economic impact in Greece, Iceland, New Zealand, and Singapore. The four countries were chosen due to their ability to contain the spread and mitigate the effects of COVID-19 on their societies.Method(s)We use document analysis based on the available national reports, media announcements, official coronavirus websites and governmental decrees in each of the four countries starting from the 1st of January o the 9th of August announcements. We apply a policy gradient to compare and examine the policies implemented in the four countries.Finding(s)The four countries have different demographic, epidemiological, socioeconomic profiles but managed to control the pandemic at an early stage in terms of total number of positive cases. The four countries managed to absorb the health system shock and decrease the case fatality ratio of COVID-19. Early interventions were crucial to avoid expected life lost in case of no early lockdown. The pandemic triggered several economic stimulus and relief measures in the four countries; the impact or the economic rebound is yet to be fully observed.Conclusion(s)We conclude that early, proactive and strict interventions along with leveraging previous experience on communicable diseases and the evolution of testing strategies are key lessons that can be synthesized from the interventions of the four countries and that could be useful for a potential second wave or similar pandemics.     

Priority allocation of pandemic influenza vaccines in Australia – Recommendations of 3 community juries

BackgroundPandemic planning has historically been oriented to respond to an influenza virus, with vaccination strategy being a key focus. As the current COVID-19 pandemic plays out, the Australian government is closely monitoring progress towards development of SARS-CoV2 vaccines as a definitive intervention. However, as in any pandemic, initial supply will likely be exceeded by demand due to limited manufacturing output.MethodsWe convened community juries in three Australian locations in 2019 to assess public acceptability and perceived legitimacy of influenza pandemic vaccination distribution strategies. Preparatory work included literature reviews on pandemic vaccine allocation strategies and on vaccine allocation ethics, and simulation modelling studies. We assumed vaccine would be provided to predefined priority groups. Jurors were then asked to recommend one of two strategies for distributing remaining early doses of vaccine: directly vaccinate people at higher risk of adverse outcomes from influenza; or indirectly protect the general population by vaccinating primary school students, who are most likely to spread infection.ResultsThirty-four participants of diverse backgrounds and ages were recruited through random digit dialling and topic-blinded social media advertising. Juries heard evidence and arguments supporting different vaccine distribution strategies, and questioned expert presenters. All three community juries supported prioritising school children for influenza vaccination (aiming for indirect protection), one by 10–2 majority and two by consensus. Justifications included that indirect protection benefits more people and is likely to be more publicly acceptable.ConclusionsIn the context of an influenza pandemic, informed citizens were not opposed to prioritising groups at higher risks of adverse outcomes, but if resources and epidemiological conditions allow, achieving population benefits should be a strategic priority. These insights may inform future SARS-CoV-2 vaccination strategies.     

COVID-19 vaccine behaviour among citizens of the Métis Nation of Ontario: A qualitative study

BackgroundThe burden of the current COVID-19 pandemic is not shared equally in Canadian society, with Indigenous Peoples being disproportionately affected. Moreover, there is a lack of research pertaining to vaccination behaviour in Métis communities. This Métis-specific and Métis-led qualitative study endeavours to understand COVID-19 vaccine behaviour among citizens of the Métis Nation of Ontario (MNO).MethodsData was collected via one-on-one interviews. Participants were recruited via the MNO’s existing social media channels. Participants filled out a screening survey indicating their intention to vaccinate against COVID-19 as yes, no, or unsure. Sixteen participants (9 yes, 3 unsure, 4 no) were interviewed. Interviews averaged 30 min, and the questions and probes were developed in collaboration with the MNO. The interviewer received Métis-specific cultural safety training. Interviews were transcribed verbatim and uploaded to NVivo 12.ResultsA deductive analysis using the Social Ecological Model framework (SEM) for vaccine behaviour and two blinded coders was used to understand the data. An additional factor, COVID-19 public health measures, was added to the framework to better capture the experiences of participants during the COVID-19 pandemic. Overall, the factors with the greatest number of coded references included Vaccine roll-out and availability, Organization of the public into priority groups, Public discourse, Interpersonal influences, Interface with health professionals, Knowledge state, Trust, and Vaccine risk perception. Bandwagoning (following others’ behaviour) and Freeloading (perceiving enough people have been vaccinated), both factors of the SEM, were not discussed. Yes, no, and unsure participant groups were compared to understand the influences of each factor based on COVID-19 vaccination intention.ConclusionsMNO citizens COVID-19 vaccine behaviour was negatively and positively influenced by a number of factors. This information will allow the MNO and public health units to better tailor their messaging for COVID-19 vaccine uptake campaigns and future pandemic emergencies.     

The impact of the COVID-19 pandemic on parents’ perceptions and acceptance of routine childhood vaccination in Canada: A national longitudinal study

BackgroundA decline in routine vaccination was reported by some countries early in the COVID-19 pandemic. In the context of the pandemic, determinants of routine childhood vaccination may have changed. Changes over time in parents’ perceptions of routine vaccines and intentions for their children during the pandemic have not been fully explored. Understanding changes provides opportunities to promote routine childhood vaccines and address factors that may compromise parents’ acceptance.MethodsWe conducted longitudinal analysis of two sequential national surveys during the pandemic (Dec 2020 and Oct/Nov 2021) to assess changes over time in Canadian parents’ perceptions of routine childhood vaccines, intentions to vaccinate, access for their children ≤ 17 years, and differences among sociodemographic characteristics. McNemar-Bowker tests were used to determine changes in parents’ responses collected at two time points.ResultsOf the 650 parents in the sample, 25.1% with a child ≤ 6 years and 20.5% with a child 7–17 years perceived that routine childhood vaccines were more important because of the pandemic. Between the two time points, parents’ confidence in the safety (72.8% to 80.2%, p <.001) and effectiveness (81.7% to 85.2%, p =.007) of routine vaccines increased, parents were more engaged in vaccine decision-making (73.4% to 79.8%, p =.006), and everyday stress preventing vaccination decreased (78.8% to 68.5%, p <.001). Acceptance of routine vaccines increased (82.9% to 86.5%, p =.021), but more parents were undecided about influenza vaccination (12.6% to 20.3%, p =.002). Compared to parents with 1 child, those with 2 children reported increased vaccination acceptance (82.6% to 87.4%, p =.024).InterpretationUnder the spotlight of COVID-19, parents’ confidence in routine vaccines, engagement in decision-making, and vaccination acceptance increased. Vaccination providers should support parents’ decision-making as they navigate routine childhood vaccine uncertainties. Differences in parents’ acceptance of routine and influenza vaccines for their children highlight the need for targeted communication strategies for specific vaccines.     

Management of COVID-19 and vaccination in Nepal: A qualitative study

Objective

The aim of this research is to investigate the perspective of citizens of Nepal on the management COVID-19, the roll-out of the vaccine, and to gain an understanding of attitudes towards the governments' handling of the COVID-19 pandemic.

Method

A qualitative methodology was used. In-depth interviews were conducted with 18 males and 23 females aged between 20 and 86 years old from one remote and one urban district of Nepal. Interviews were conducted in November and December 2021. A thematic approach was used to analyse the data, utilising NVivo 12 data management software.

Result

Three major themes were identified: (1) Peoples' perspective on the management of COVID-19, (2) people's perception of the management of COVID-19 vaccination and (3) management and dissemination of information. It was found that most participants had heard of COVID-19 and its mitigation measures, however, the majority had limited understanding and knowledge about the disease. Most participants expressed their disappointment concerning poor testing, quarantine, vaccination campaigns and poor accountability from the government towards the management of COVID-19. Misinformation and stigma were reported as the major factors contributing to the spread of COVID-19. People's knowledge and understanding were mainly shaped by the quality of the information they received from various sources of communication and social media. This heavily influenced their response to the pandemic, the preventive measures they followed and their attitude towards vaccination.

Conclusion

Our study concludes that the study participants' perception was that testing, quarantine centres and vaccination campaigns were poorly managed in both urban and rural settings in Nepal. Since people's knowledge and understanding of COVID-19 are heavily influenced by the quality of information they receive, we suggest providing contextualised correct information through a trusted channel regarding the pandemic, its preventive measures and vaccination. This study recommends that the government proactively involve grassroots-level volunteers like Female Community Health Volunteers to effectively prepare for future pandemics.

Patient and Public Contribution

This study was based on in-depth interviews with 41 people from diverse socioeconomic backgrounds. This study would not have been possible without their participation.     

The impact of health policies and vaccine rollout on the COVID-19 pandemic waves in Italy

BackgroundOver the course of the COVID-19 pandemic in Italy, different response measures were taken to contain the spread of the virus. These include a variety of non-pharmaceutical interventions and a mass vaccination campaign. While not definitive, epidemiological measures provide some indication of the impact of such measures on the dynamics of the pandemic and lessons to better prepare for future emergencies.ObjectiveTo describe the impact of vaccine rollout and health policies on the evolution of the COVID-19 pandemic in Italy from March 2020 to October 2021 using a set of epidemiological indicators.MethodsWe performed a time-trend analysis of new confirmed COVID-19 cases, patients in hospital, and deaths. Using line charts, we informally assessed the relationship of these indicators with the immunization campaign and other health policies. Daily aggregate data were gathered from GitHub repositories of certified data from Italy's Government and Civil Protection.ResultsThe immunization coverage increased starting in March 2021, with a parallel decrease in COVID-19 infections, hospitalizations, and deaths. Despite different implementation approaches, the vaccine coverage growth rate had a similar pattern across regions. A comprehensive approach including measures such as requiring face masks and a “Green Pass” to enter indoor places also helped contain the pandemic.ConclusionsThe vaccine rollout had a major effect on COVID-19 in Italy, especially on hospitalizations and deaths. Before the vaccine was available, however, other non-pharmaceutical interventions also helped to contain the spread of the virus and mitigate its effect on the population.     

Effectiveness of adenovirus type 5 vectored and inactivated COVID-19 vaccines against symptomatic COVID-19, COVID-19 pneumonia,and severe COVID-19 caused by the B.1.617.2 (Delta) variant: Evidence from an outbreak in Yunnan,China, 2021

BackgroundIn partial response to the coronavirus disease 2019 (COVID-19) pandemic, countries around the world are conducting large-scale vaccination campaigns. Real-world estimates of vaccine effectiveness (VE) against the B.1.617.2 (Delta) variant are still limited. An outbreak in Ruili city of China provided an opportunity to evaluate VE against the Delta variant of two types of COVID-19 vaccines in use in China and globally – inactivated (CoronaVac and BBIBP-CorV) and adenovirus type 5 vectored (Convidecia) vaccines.MethodsWe estimated VE using a retrospective cohort study two months after the Ruili vaccination campaign (median: 63 days). Close contacts of infected people (Chinese nationality, 18 years and above) were included to assess VE against symptomatic Covid-19, COVID-19 pneumonia, and severe COVID-19. We calculated the relative risks (RR) of the outcomes for unvaccinated compared with fully vaccinated individuals. We used logistic regression analyses to estimate adjusted VEs, controlling for gender and age group (18–59 years and 60 years and over).We compared unvaccinated and fully vaccinated individuals on duration of RT-PCR positivity and Ct value.FindingsThere were 686 close contacts eligible for VE estimates. Adjusted VE of ad5-vectored vaccine was 61.5% (95% CI, 9.5–83.6) against symptomatic COVID-19, 67.9% (95%CI: 1.7–89.9) against pneumonia, and 100% (95%CI: 36.6–100) against severe/critical illness. For the two inactivated vaccines, combined VE was 74.6% (95% CI, 36.0–90.0) against symptomatic COVID-19, 76.7% (95% CI: 19.3–93.3) against pneumonia, and 100% (95% CI: 47.6–100) against severe/critical COVID-19. There were no statistically significant differences in VE between two inactivated vaccines for symptomatic COVID-19 and for pneumonia, nor were there statistically significant differences between inactivated and ad5-vectored VE in any of the three outcomes. The median durations of RT-PCR positivity were 17 days for fifteen people vaccinated with an inactivated vaccine, 18 days for forty-four people vaccinated with the Ad5 vectored vaccine, and 26 days for eleven unvaccinated individuals. InterpretationThese results provide reassuring evidence that the three vaccines are effective at preventing Delta-variant COVID-19 in short term following vaccination campaign, and are most effective at preventing more serious illness. The findings of reduced duration of RT-PCR positivity and length of hospital stay associated with full vaccination suggests potential saving of health-care system resources.     

COVID-19 vaccine intentions in the United States,a social-ecological framework

BackgroundCOVID-19 vaccine hesitancy is a major obstacle for pandemic mitigation. As vaccine hesitancy occurs along multiple dimensions, we used a social-ecological framework to guide the examination of COVID-19 vaccine intentions.MethodsUsing an online survey in the US conducted in July 2020, we examined intentions to obtain a COVID-19 vaccine, once available. 592 respondents provided data, including measures of demographics, vaccine history, social norms, perceived risk, and trust in sources of COVID-19 information. Bivariate and multivariate multinomial models were used to compare respondents who intended to be vaccinated against COVID-19 to respondents who did not intend or were ambivalent about COVID-19 vaccination.ResultsOnly 59.1% of the sample reported that they intended to obtain a COVID-19 vaccine. In the multivariate multinomial model, those respondents who did not intend to be vaccinated, as compared to those who did, had significantly lower levels of trust in the CDC as a source of COVID-19 information (aOR = 0.29, CI = 0.17–0.50), reported lower social norms of COVID-19 preventive behaviors (aOR = 0.67, CI 0.51–0.88), scored higher on COVID-19 Skepticism (aOR = 1.44, CI = 1.28–1.61), identified as more politically conservative (aOR = 1.23, CI = 1.05–1.45), were less likely to have obtained a flu vaccine in the prior year (aOR = 0.21, CI = 0.11–0.39), were less likely to be female (aOR = 0.51, CI = 0.29–0.87), and were much more likely to be Black compared to White (aOR = 10.70, CI = 4.09–28.1). A highly similar pattern was observed among those who were ambivalent about receiving a COVID-19 vaccine compared to those who intended to receive one.ConclusionThe results of this study suggest several avenues for COVID-19 vaccine promotion campaigns, including social network diffusion strategies and cross-partisan messaging, to promote vaccine trust. The racial and gender differences in vaccine intentions also suggest the need to tailor campaigns based on gender and race.     

Caregiver willingness to vaccinate their children against COVID-19: Cross sectional survey

BackgroundMore than 100 COVID-19 vaccine candidates are in development since the SARS-CoV-2 genetic sequence was published in January 2020. The uptake of a COVID-19 vaccine among children will be instrumental in limiting the spread of the disease as herd immunity may require vaccine coverage of up to 80% of the population. Prior history of pandemic vaccine coverage was as low as 40% among children in the United States during the 2009 H1N1 influenza pandemic.PurposeTo investigate predictors associated with global caregivers’ intent to vaccinate their children against COVID-19, when the vaccine becomes available.MethodAn international cross sectional survey of 1541 caregivers arriving with their children to 16 pediatric Emergency Departments (ED) across six countries from March 26 to May 31, 2020.Results65% (n = 1005) of caregivers reported that they intend to vaccinate their child against COVID-19, once a vaccine is available. A univariate and subsequent multivariate analysis found that increased intended uptake was associated with children that were older, children with no chronic illness, when fathers completed the survey, children up-to-date on their vaccination schedule, recent history of vaccination against influenza, and caregivers concerned their child had COVID-19 at the time of survey completion in the ED. The most common reason reported by caregivers intending to vaccinate was to protect their child (62%), and the most common reason reported by caregivers refusing vaccination was the vaccine’s novelty (52%).ConclusionsThe majority of caregivers intend to vaccinate their children against COVID-19, though uptake will likely be associated with specific factors such as child and caregiver demographics and vaccination history. Public health strategies need to address barriers to uptake by providing evidence about an upcoming COVID-19 vaccine’s safety and efficacy, highlighting the risks and consequences of infection in children, and educating caregivers on the role of vaccination.     

Declining influenza vaccination rates in an underserved pediatric primary care center during the COVID-19 pandemic

BackgroundInfluenza vaccination rates are decreasing in the United States. Disinformation surrounding COVID-related public health protections and SARS-CoV-2 vaccine roll-out may have unintended consequences impacting pediatric influenza vaccination. We assessed influenza vaccination rates before and during the COVID-19 pandemic in one pediatric primary care center, serving a minoritized population.MethodsA cross-sectional study assessed influenza vaccination rates for children aged 6 months to 12 years over the following influenza seasons (September-May): 1) 2018–19 and 2019–20 (pre-pandemic), and 2) 2020–21 and 2021–22 (intra-pandemic). Demographics and responses to social risk questionnaires were extracted from electronic health records. Total tetanus vaccinations across influenza seasons served as approximations of general vaccination rates. Generalized linear regression models with robust standard errors evaluated differences in demographics, social risks, and influenza vaccination rates by season. Multivariable logistic regression with robust standard errors evaluated associations between influenza season, demographics, social risks, and influenza vaccination.ResultsMost patients were young (mean age ～ 6 years), non-Hispanic Black (～80%), and publicly insured (～90%). Forty-two percent of patients eligible to receive the influenza vaccine who were seen in 2019–20 influenza season received the influenza vaccine, compared to 30% in 2021–22. Influenza and tetanus vaccination rates decreased during the COVID-19 pandemic (p < 0.01). The 2020–21 and 2021–22 influenza seasons, older age, Black race, and self-pay were associated with decreased influenza vaccine administration (p < 0.05).ConclusionsInfluenza vaccination rates within one pediatric primary care center decreased during the COVID-19 pandemic and have not rebounded, particularly for older children, those identifying as Black, and those without insurance.     

Reasons for COVID-19 Vaccine Hesitancy Among Chinese People Living With HIV/AIDS: Structural Equation Modeling Analysis

BackgroundMany countries and organizations recommended people living with HIV/AIDS (PLWHA) receive the COVID-19 vaccine. However, vaccine hesitancy still exists and becomes a barrier for promoting COVID-19 vaccination among PLWHA.ObjectiveThis study aims to investigate factors that contributed to COVID-19 vaccine hesitancy among PLWHA.MethodsThe study used a multicenter cross-sectional design and an online survey mode. We recruited PLWHA aged 18-65 years from 5 metropolitan cities in China between January 2021 and February 2021. Participants completed an online survey through Golden Data, a widely used encrypted web-based survey platform. Multiple linear regression models were used to assess the background characteristics in relation to COVID-19 vaccine hesitancy, and structural equation modeling was performed to assess the relationships among perceived benefits, perceived risks, self-efficacy, subjective norms, and COVID-19 vaccine hesitancy.ResultsAmong 1735 participants, 41.61% (722/1735) reported COVID-19 vaccine hesitancy. Older age, no other vaccinations in the past 3 years, and having chronic disease history were positively associated with COVID-19 vaccine hesitancy. Structural equation modeling revealed a direct relationship of perceived benefits, perceived risks, and subjective norms with self-efficacy and vaccine hesitancy and an indirect relationship of perceived benefits, perceived risks, and subjective norms with vaccine hesitancy. Moreover, self-efficacy toward COVID-19 vaccination was low. PLWHA had concerns of HIV disclosure during COVID-19 vaccination. Family member support could have an impact on COVID-19 vaccination decision-making.ConclusionsCOVID-19 vaccine hesitancy was high among PLWHA in China. To reduce COVID-19 vaccine hesitancy, programs and strategies should be adopted to eliminate the concerns for COVID-19 vaccination, disseminate accurate information on the safety and efficacy of the COVID-19 vaccine, encourage family member support for COVID-19 vaccination, and improve PLWHA’s trust of medical professionals.     

Compliance,procrastination and refusal: American COVID-19 vaccination trust and value orientation

IntroductionCOVID-19 vaccine hesitancy studies, most of which were completed prior to the release of the vaccine, speculated on factors that might influence inoculation intention when a vaccine was introduced. This paper examines actual vaccination decisions among US residents after COVID-19 vaccines were approved, with a focus on trust in vaccine effectiveness, increased trust in government pandemic response, and individual-versus-collective value orientation.MethodThe data set was from the Kaiser Family Foundation COVID-19 Vaccine Monitor, a nationally representative sample reflecting the opinions of 1519 American adults aged 18 and above. Data were collected in September 2021—approximately nine months after the first COVID-19 vaccines were approved for distribution. Indicators of trust in vaccine effectiveness included individual opinions regarding breakthrough infections and vaccine boosters. Increased trust in government indicated approval of official COVID-19 responses, and value orientation denoted respondent emphasis on personal choice versus protecting the health of others. We established three categories of a vaccine hesitancy dependent variable: none, some, and full rejection. A multinomial regression analysis was employed to compare vaccine hesitancy in three pairs of contrasting groups.ResultsWhile we noted distinct patterns in decision-making factors for each of the contrasting pairs, we also observed strong effects for trust in vaccine effectiveness and value orientation on vaccine decisions across all three. Both effects were more substantial than those associated with three control variables—social-demographic characteristics, political party affiliation, and health risk.ConclusionOur findings suggest that in order to increase vaccination rates, policymakers and influencers should focus on reducing individual scepticism over breakthrough infections and vaccine boosters, and on influencing a value orientation shift from personal choice to social responsibility.     

Individual factors influencing COVID-19 vaccine acceptance in between and during pandemic waves (July–December 2020)

BackgroundA year after the start of the COVID-19 outbreak, the global rollout of vaccines gives us hope of ending the pandemic. Lack of vaccine confidence, however, poses a threat to vaccination campaigns. This study aims at identifying individuals’ characteristics that explain vaccine willingness in Flanders (Belgium), while also describing trends over time (July–December 2020).MethodsThe analysis included data of 10 survey waves of the Great Corona Survey, a large-scale online survey that was open to the general public and had 17,722–32,219 respondents per wave. Uni- and multivariable general additive models were fitted to associate vaccine willingness with socio-demographic and behavioral variables, while correcting for temporal and geographical variability.ResultsWe found 84.2% of the respondents willing to be vaccinated, i.e., respondents answering that they were definitely (61.2%) or probably (23.0%) willing to get a COVID-19 vaccine, while 9.8% indicated maybe, 3.9% probably not and 2.2% definitely not. In Flanders, vaccine willingness was highest in July 2020 (90.0%), decreased over the summer period to 80.2% and started to increase again from late September, reaching 85.9% at the end of December 2020. Vaccine willingness was significantly associated with respondents’ characteristics: previous survey participation, age, gender, province, educational attainment, household size, financial situation, employment sector, underlying medical conditions, mental well-being, government trust, knowing someone with severe COVID-19 symptoms and compliance with restrictive measures. These variables could explain much, but not all, variation in vaccine willingness.ConclusionsBoth the timing and location of data collection influence vaccine willingness results, emphasizing that comparing data from different regions, countries and/or timepoints should be done with caution. To maximize COVID-19 vaccination coverage, vaccination campaigns should focus on (a combination of) subpopulations: aged 31–50, females, low educational attainment, large households, difficult financial situation, low mental well-being and labourers, unemployed and self-employed citizens.     

The impact of COVID-19 vaccination delay: A data-driven modeling analysis for Chicago and New York City

BackgroundBy the beginning of December 2020, some vaccines against COVID-19 already presented efficacy and security, which qualify them to be used in mass vaccination campaigns. Thus, setting up strategies of vaccination became crucial to control the COVID-19 pandemic.MethodsWe use daily COVID-19 reports from Chicago and New York City (NYC) from 01-Mar2020 to 28-Nov-2020 to estimate the parameters of an SEIR-like epidemiological model that accounts for different severity levels. To achieve data adherent predictions, we let the model parameters to be time-dependent. The model is used to forecast different vaccination scenarios, where the campaign starts at different dates, from 01-Oct-2020 to 01-Apr-2021. To generate realistic scenarios, disease control strategies are implemented whenever the number of predicted daily hospitalizations reaches a preset threshold.ResultsThe model reproduces the empirical data with remarkable accuracy. Delaying the vaccination severely affects the mortality, hospitalization, and recovery projections. In Chicago, the disease spread was under control, reducing the mortality increment as the start of the vaccination was postponed. In NYC, the number of cases was increasing, thus, the estimated model predicted a much larger impact, despite the implementation of contention measures.The earlier the vaccination campaign begins, the larger is its potential impact in reducing the COVID-19 cases, as well as in the hospitalizations and deaths. Moreover, the rate at which cases, hospitalizations and deaths increase with the delay in the vaccination beginning strongly depends on the shape of the incidence of infection in each city.     

“Somebody Like Me”: Understanding COVID-19 Vaccine Hesitancy among Staff in Skilled Nursing Facilities

ObjectiveThe vaccination of skilled nursing facility (SNF) staff is a critical component in the battle against COVID-19. Together, residents and staff constitute the single most vulnerable population in the pandemic. The health of these workers is completely entangled with the health of those they care for. Vaccination of SNF staff is key to increasing uptake of the vaccine, reducing health disparities, and reopening SNFs to visitors. Yet, as the vaccine rollout begins, some SNF staff are declining to be vaccinated. The purpose of this article is to describe reasons for COVID-19 vaccine hesitancy reported by staff of skilled nursing facilities and understand factors that could potentially reduce hesitancy.DesignFive virtual focus groups were conducted with staff of SNFs as part of a larger project to improve vaccine uptake.Setting and ParticipantsFocus groups with 58 staff members were conducted virtually using Zoom.MeasuresFocus groups sought to elicit concerns, perspectives, and experiences related to COVID-19 testing and vaccination.ResultsOur findings indicate that some SNF staff are hesitant to receive the COVID-19 vaccine. Reasons for this hesitancy include beliefs that the vaccine has been developed too fast and without sufficient testing; personal fears about pre-existing medical conditions, and more general distrust of the government.Conclusions and ImplicationsSNF staff indicate that seeing people like themselves receive the vaccination is more important than seeing public figures. We discuss the vaccination effort as a social enterprise and the need to develop long-term care provider-academic-community partnerships in response to COVID-19 and in expectation of future pandemics.     

COVID-19 in Finland: Vaccination strategy as part of the wider governing of the pandemic

ObjectivesTo analyze the vaccination strategy as part of wider public governing of the COVID-19 pandemic in Finland.MethodsThe study provides a synthesis of vaccination strategy and health policy measures, as well as economic challenges, in the COVID-19 pandemic in Finland. The analysis is based on the systematic collection and reviewing of documents and reports. The review was complemented with relevant pandemic and vaccination monitoring data from Finland.ResultsThe vaccination strategy approved by the Finnish Government in December 2020 prioritised various risk groups and health and social care professionals attending to COVID-19 patients. The Government has purchased COVID-19 vaccines through the EU joint procurement programme. Vaccinations were organised by municipalities and offered free of charge. The Government recommends universal vaccinations, including foreign residents and undocumented migrants. In 2021, the Government adopted a revised COVID-19 hybrid strategy, which aimed to dismantle wide restrictions as a means to control the epidemic. Despite high vaccination coverage, the Omicron variant became widespread in the population. The economic consequences of the pandemic have been less severe than expected.ConclusionsIn the approach to manage the pandemic, the vaccination strategy has a central role. Finland has probably benefitted from the EU joint vaccine procurement programme. The rapid launch of the vaccinations was supported by the existing vaccination capacity in municipalities. High vaccine coverage was seen as a key in opening society. Although a relatively high vaccination rate was not able to stop the spread of Omicron in late 2021, it has efficiently curbed serious cases and kept the death rate low.     

Vaccination willingness,vaccine hesitancy,and estimated coverage at the first round of COVID-19 vaccination in China: A national cross-sectional study

BackgroundVaccination against coronavirus disease 2019 (COVID-19) has become an important public health solution. To date, there has been a lack of data on COVID-19 vaccination willingness, vaccine hesitancy, and vaccination coverage in China since the vaccine has become available.MethodsWe designed and implemented a cross-sectional, population-based online survey to evaluate the willingness, hesitancy, and coverage of the COVID-19 vaccine among the Chinese population. 8742 valid samples were recruited and classified as the vaccine-priority group (n = 3902; 44.6%) and the non-priority group (n = 4840; 55.4%).ResultsThe proportion of people’s trust in the vaccine, delivery system, and government were 69.0%, 78.0% and 81.3%, respectively. 67.1% of the participants were reportedly willing to accept the COVID-19 vaccination, while 9.0% refused it. 834 (35.5%) reported vaccine hesitancy, including acceptors with doubts (48.8%), refusers (39.4%), and delayers (11.8%). The current coverage was 34.4%, far from reaching the requirements of herd immunity. The predicted rate of COVID-19 vaccination was 64.9%, 68.9% and 81.1% based on the rates of vaccine hesitancy, willingness, and refusal, respectively.ConclusionsThe COVID-19 vaccine rate is far from reaching the requirements of herd immunity, which will require more flexible and comprehensive efforts to improve the population’s confidence and willingness to vaccinate. It should be highlighted that vaccination alone is insufficient to stop the pandemic; further efforts are needed not only to increase vaccination coverage but also to maintain non-specific prevention strategies.
