ABSTRACT This paper uses the vocabulary of ‘medical populism’ to identify and analyse the political constructions of (and responses to) the COVID-19 pandemic in Brazil, the Philippines, and the United States from January to mid-July 2020, particularly by the countries’ heads of state: Jair Bolsonaro, Rodrigo Duterte, and Donald Trump. In all three countries, the leaders’ responses to the outbreak can be characterised by the following features: simplifying the pandemic by downplaying its impacts or touting easy solutions or treatments, spectacularizing their responses to crisis, forging divisions between the ‘people’ and dangerous ‘others’, and making medical knowledge claims to support the above. Taken together, the case studies illuminate the role of individual political actors in defining public health crises, suggesting that medical populism is not an exceptional, but a familiar response to them. This paper concludes by offering recommendations for global health in anticipating and responding to pandemics and infectious disease outbreaks. 相似文献

ABSTRACTThe article describes the growing anti-vaccine movements in the context of right-wing populism, which is also gaining popularity around the world. According to the authors, these two phenomena have a lot in common, and the activists of the anti-vaccine movements often intermingle with populist right-wing movements. The connection between anti-vaccine activists and populists is illustrated in the analysis of discourse and anti-vaccine arguments presented in materials on the Polish-language YouTube channel, as well as in comments on YouTube forums. The slogans of the defence of ‘ordinary people’ against ‘corrupt elites’ in the medical dimension indicate a dislike for ‘medical conspiracy’ and doctors corrupted by pharmaceutical concerns. Just like right-wing populists, opponents of vaccines in Poland refer to nationalist slogans and have an aversion to the European Union. In addition to the rejection of the WHO standards on sex education and the sceptic attitude to environmental changes, the rejection of vaccines is another manifestation of the conspiracy ideologies of right-wing populists in Poland that may affect health and health policy. In the area of public health, this means rejecting medical knowledge and replacing it with myths and prejudices proclaimed by anti-vaccine movements, among others. 相似文献

BackgroundRoutine maternal immunisation against influenza and pertussis are recommended by the WHO to protect mother and child, and new vaccines are under development. Introducing maternal vaccines into national programmes requires an understanding of vaccine delivery costs – particularly in low resource settings.MethodsWe searched Medline, Embase, Econlit, and Global Health for studies reporting costs of delivering vaccination during pregnancy but excluded studies that did not separate the vaccine purchase price. Extracted costs were inflated and converted to 2018 US dollars.ResultsSixteen studies were included, of which two used primary data to estimate vaccine delivery costs. Costs per dose ranged from $0.55 to $0.64 in low-income countries, from $1.25 to $6.55 for middle-income countries, and from $5.76 to $39.87 in high-income countries.ConclusionsMore research is needed on the costs of delivering maternal immunisation during pregnancy, and of integrating vaccine delivery into existing programmes of antenatal care especially in low and middle-income countries. 相似文献

BackgroundGrowing narratives emphasize using primary care physicians as leaders in efforts to promote COVID-19 vaccination among the vaccine hesitant. Critically however, little is known about vaccine confidence among primary care physicians themselves. The objective of this study was to assess both physician confidence that in general, vaccines are safe, effective, and important, as well as physician confidence in each COVID-19 vaccine in the United States.MethodsWe rely on data from a national survey of primary care physicians conducted from May 14-May 25, 2021. We assess the influence of demographic, social, and political factors on physician beliefs that in general, vaccines are safe, effective, and important, as well as physician confidence in the safety of the Moderna, Pfizer, and Johnson & Johnson COVID-19 vaccines.Results10.1% of primary care physicians do not agree that, in general, vaccines are safe, 9.3% do not agree they are effective, and 8.3% do not agree they are important. While 68.7% of physicians were ‘very confident’ in the safety of the Moderna vaccine and 72.7% were ‘very confident’ in the safety of the Pfizer vaccine, only 32.1% of physicians were ‘very confident’ in the safety of the Johnson & Johnson COVID-19 vaccine.ConclusionA troubling proportion of primary care physicians lack high levels of vaccine confidence. These physicians may not be well positioned to actively promote COVID-19 vaccination even as political and media narratives push physicians to lead this effort. Interventions aimed at improving vaccine confidence among some physicians may be needed so that all physicians can fulfill needed roles as trusted vaccine communicators. 相似文献

BackgroundIntroduction of new vaccines in low- and lower middle-income countries has accelerated since Gavi, the Vaccine Alliance was established in 2000. This study sought to (i) estimate the costs of introducing pneumococcal conjugate vaccine, rotavirus vaccine and a second dose of measles vaccine in Zambia; and (ii) assess affordability of the new vaccines in relation to Gavi’s co-financing and eligibility policies.MethodsData on ‘one-time’ costs of cold storage expansions, training and social mobilisation were collected from the government and development partners. A detailed economic cost study of routine immunisation based on a representative sample of 51 health facilities provided information on labour and vaccine transport costs. Gavi co-financing payments and immunisation programme costs were projected until 2022 when Zambia is expected to transition from Gavi support. The ability of Zambia to self-finance both new and traditional vaccines was assessed by comparing these with projected government health expenditures.Results‘One-time’ costs of introducing the three vaccines amounted to US$ 0.28 per capita. The new vaccines increased annual immunisation programme costs by 38%, resulting in economic cost per fully immunised child of US$ 102. Co-financing payments on average increased by 10% during 2008–2017, but must increase 49% annually between 2017 and 2022. In 2014, the government spent approximately 6% of its health expenditures on immunisation. Assuming no real budget increases, immunisation would account for around 10% in 2022. Vaccines represented 1% of government, non-personnel expenditures for health in 2014, and would be 6% in 2022, assuming no real budget increases.ConclusionWhile the introduction of new vaccines is justified by expected positive health impacts, long-term affordability will be challenging in light of the current economic climate in Zambia. The government needs to both allocate more resources to the health sector and seek efficiency gains within service provision. 相似文献

Objective: To explore New Zealand's four major daily newspapers' coverage of immunisation with regards to errors of fact and fallacy in construction of immunisation‐related arguments. Methods: All articles from 2002 to 2007 were assessed for errors of fact and logic. Fact was defined as that which was supported by the most current evidence‐based medical literature. Errors of logic were assessed using a classical taxonomy broadly based in Aristotle's classifications. Results: Numerous errors of both fact and logic were identified, predominantly used by anti‐immunisation proponents, but occasionally by health authorities. The proportion of media articles reporting exclusively fact changes over time during the life of a vaccine where new vaccines incur little fallacious reporting and established vaccines generate inaccurate claims. Fallacious arguments can be deconstructed and classified into a classical taxonomy including non sequitur and argumentum ad Hominem. Conclusion: Most media ‘balance’ given to immunisation relies on ‘he said, she said’ arguments using quotes from opposing spokespersons with a failure to verify the scientific validity of both the material and the source. Implications: Health professionals and media need training so that recognising and critiquing public health arguments becomes accepted practice: Stronger public relations strategies should challenge poor quality articles to journalists' code of ethics and the health sector needs to be proactive in predicting and pre‐empting the expected responses to introduction of new public health initiatives such as a new vaccine. 相似文献

BackgroundVaccination intention is key to the success of any vaccination programme, alongside vaccine availability and access. Public intention to take a COVID-19 vaccine is high in England and Wales compared to other countries, but vaccination rate disparities between ethnic, social and age groups has led to concern.MethodsOnline survey of prospective household community cohort study participants across England and Wales (Virus Watch). Vaccination intention was measured by individual participant responses to ‘Would you accept a COVID-19 vaccine if offered?’, collected in December 2020 and February 2021. Responses to a 13-item questionnaire collected in January 2021 were analysed using factor analysis to investigate psychological influences on vaccination intention.ResultsSurvey response rate was 56% (20,785/36,998) in December 2020 and 53% (20,590/38,727) in February 2021, with 14,880 adults reporting across both time points. In December 2020, 1,469 (10%) participants responded ‘No’ or ‘Unsure’. Of these people, 1,266 (86%) changed their mind and responded ‘Yes’ or ‘Already had a COVID-19 vaccine’ by February 2021. Vaccination intention increased across all ethnic groups and levels of social deprivation. Age was most strongly associated with vaccination intention, with 16–24-year-olds more likely to respond “Unsure” or “No” versus “Yes” than 65–74-year-olds in December 2020 (OR: 4.63, 95 %CI: 3.42, 6.27 & OR 7.17 95 %CI: 4.26, 12.07 respectively) and February 2021 (OR: 27.92 95 %CI: 13.79, 56.51 & OR 17.16 95 %CI: 4.12, 71.55). The association between ethnicity and vaccination intention weakened, but did not disappear, over time. Both vaccine- and illness-related psychological factors were shown to influence vaccination intention.ConclusionsFour in five adults (86%) who were reluctant or intending to refuse a COVID-19 vaccine in December 2020 had changed their mind in February 2021 and planned to accept, or had already accepted, a vaccine. 相似文献

BackgroundVaccine hesitancy constitutes a major threat to the Global Polio Eradication Initiative (GPEI), and to further expansion of routine immunisation. Understanding hesitancy, leading in some cases to refusal, is vital to the success of GPEI. Re-emergence of circulating wild poliovirus in northern Nigeria in mid-2016, after 24 months polio-free, gives urgency to this. But it is equally important to protect and sustain the global gains available through routine immunisation in a time of rising scepticism and potential rejection of specific vaccines or immunisation more generally.Methods and findingsThis study is based on a purposive sampling survey of 1653 households in high- and low-performing rural, semiurban and urban areas of three high-risk states of northern Nigeria in 2013–14 (Sokoto, Kano and Bauchi). The survey sought to understand factors at household and community level associated with propensity to refuse polio vaccine.Wealth, female education and knowledge of vaccines were associated with lower propensity to refuse oral polio vaccine (OPV) among rural households. But higher risk of refusal among wealthier, more literate urban household rendered these findings ambiguous. Ethnic and religious identity did not appear to be associated with risk of OPV refusal.Risk of vaccine refusal was highly clustered among households within a small sub-group of sampled settlements. Contrary to expectations, households in these settlements reported higher levels of expectation of government as service provider, but at the same time lesser confidence in the efficacy of their relations with government.ConclusionsResults suggest that strategies to address the micro-political dimension of vaccination – expanding community-level engagement, strengthening the role of local government in public health, and enhancing public participation of women – should be effective in reducing non-compliance, as an important set of strategies complementary to conventional didactic/educational approaches and working through religious and traditional ‘influencers’. 相似文献

IntroductionThis study aimed to understand barriers and enablers, future strategies, communication approaches and resources needed for COVID-19 vaccination among migrant communities in Melbourne, Australia.Material and methodsWe interviewed 24 immunisation providers who deliver immunisation services to migrant populations in Melbourne. We used the WHO Behavioural and Social Drivers framework (underlined) to organise barriers and enablers to COVID-19 vaccination.ResultsParticipants believed migrants had concerns about vaccine safety and efficacy and saw vaccines as minimally beneficial in the ‘low COVID-19′ environment of Australia (what people think and feel). Healthcare providers with established relationships within migrant communities played key roles in vaccine advocacy (social processes). Migrants’ vaccine motivation was mediated by health literacy, institutional trust and previous experiences with health services. Practical issues included perceived lack of information on vaccine booking process and accessibility challenges.ConclusionsStrategies to increase migrant vaccine coverage should utilise immunisation providers with community links and trusted local vaccine ambassadors to engage and address community vaccine concerns. 相似文献

Abstract Control and reduction of infectious diseases is a key to attaining the Millennium Development Goals. An important element of this work is the successful immunisation, especially in resource-poor countries. Mass immunisation, most intensively in the case of eradication, depends on a combination of reliable demand (e.g. public willingness to comply with the vaccine protocol) and effective supply (e.g. robust, generally state-led, vaccine delivery). This balance of compliance and enforceability is, quintessentially, socio-political in nature – conditioned by popular perceptions of disease and risk, wider conditions of economic development and poverty, technical aspects of vaccine delivery, and the prevailing international norms regarding power relations between states and peoples. In the past 100 years, three out of six disease eradication programmes have failed. The explanations for failure have focused on biotechnical and managerial or financial issues. Less attention is paid to socio-political aspects. Yet socio-political explanations are key. Eradication is neither inherently prone to failure, nor necessarily doomed in the case of polio. However, eradication, and similar mass immunisation initiatives, which fail to address social and political realities of intervention may be. A comparison of the smallpox and polio eradication programmes illustrates the importance of disease-specific socio-political analysis in programme conceptualisation, design, and management. 相似文献

BackgroundOn 8th April 2021, the Australian Technical Advisory Group on Immunisation (ATAGI) made the Pfizer-BioNtech (Comirnaty) vaccine the “preferred” vaccine for adults in Australia aged < 50 years due to a risk of thrombosis with thrombocytopenia syndrome (TTS) following AstraZeneca vaccination. We sought to understand whether this impacted COVID-19 vaccine intentions.MethodWe undertook qualitative interviews from February – April 2021 before and after the program change with 28 adults in Perth, Western Australia. Using our COVID-19 vaccine intentions model, we assessed changes in participants’ COVID-19 vaccine intention before and after the program change. Participants were classified as 1) ‘acceptors’: no concerns about COVID-19 vaccine safety, efficacy, access and would accept whatever vaccine is offered, 2) ‘cautious acceptors’: some concerns and would prefer a particular vaccine brand but would accept whatever is offered, 3) ‘Wait awhile’: for more data, easier access, for another vaccine brand, a greater perceived COVID-19 threat or until mandatory, or 4) ‘refuser’: no intention to vaccinate due to concerns about safety and/or efficacy.ResultsBefore the change, 7/18 of those aged < 50 years were ‘acceptors,’ 10/18 were ‘cautious acceptors’ and 1/18 was ‘wait awhile.’ Overall, 14/18 participants had the same COVID-19 vaccine intention after the change; 4/18 became more concerned. For those aged ≥ 50 years and before the change, 5/10 were ‘acceptors’ and 5/10 were ‘cautious acceptors.’ After the change, 8/10 still had the same COVID-19 vaccine intention; 2/10 became more cautious. The major concern before the program change was COVID-19 vaccines having different vaccine efficacy; the concern pivoted to safety.ConclusionThe majority of participants were ‘cautious acceptors’ who intended on being vaccinated; many had this intention before and after the program change. The Australian government, health care providers and media need to better address COVID-19 vaccine concerns to assist those with COVID-19 vaccine intentions receive a vaccine. 相似文献

Introduction‘No Jab, No Play’ and ‘No Jab, No Pay’ mandatory immunisation policies were introduced in the state of Victoria and Australia-wide, respectively, in January 2016. They restrict access to childcare/kindergarten and family assistance payments respectively, for under-vaccinated children. We aimed to describe the proportion of attendees to immunisation services of a tertiary hospital, the Royal Children’s Hospital Melbourne (RCH), who were motivated by the policies to discuss or catch-up vaccination. We explored the association between motivation by policies, vaccine hesitancy (VH) and intent to seek medical exemption, with vaccine-uptake.MethodsParents/Guardians and clinicians completed surveys October 2016-May 2017 from the nurse-led immunisation Drop in Centre (DIC) or physician-led Specialist Immunisation Clinic (SIC). Vaccine-uptake was measured using the Australian Immunisation Register (AIR) at baseline, 1 and 7 months post-attendance. The association between vaccine-uptake, motivation by policies and VH was explored by logistic regression.ResultsOf 607 children, 393 (65%) were from the DIC and 214 (35%) SIC. 74 (12%) parents were motivated by the policies to attend immunisation services and 19% were VH. Only 50% of VH parents planned to catch-up vaccination for enrolment to childcare/kindergarten. Seven months post-attendance there was no association between motivation by policies and full vaccination status (difference 10%, OR 0.42, CI 0.17–1.1, p 0.08). Fewer children were fully immunised at 7 months if their parents were VH (difference 18%; OR 0.24, CI 0.1–0.54, p < 0.001) or seeking medical exemption (difference 33%, OR 0.08, CI 0.01–0.6, p 0.015).ConclusionThe ‘No Jab’ policies motivated attendance to a tertiary immunisation service. However, children of vaccine hesitant parents and those seeking medical exemption to immunisation were less likely to be fully immunised after attendance, than at baseline. The ‘No Jab’ policies may not be changing vaccination behavior as intended for vaccine hesitant parents who are one of the key target groups, with further evaluation required. 相似文献

On the 4 February 2019, the Western Cape Department of Health’s Facebook page announced the implementation of a school-based vaccination campaign aimed to administer the first doses of human papillomavirus (HPV) vaccine in public schools to Grade 4 girls who are nine years old. This announcement was met with a flurry of social media responses posted on the campaign’s Facebook page. This study identifies determinants of vaccine hesitancy amongst responses provided by social media users to this post. On 8 March 2019, we conducted a qualitative study including all 157 comments to the Facebook post. The post had 659 ‘emotion’ reactions: 574 “likes”, 62 “loves”, 21 “angry faces”, 2 “laughs”, 2 “wows” and 1 “sad face”. An overwhelming majority (636/659 i.e. 97%) of reactions were favourable to the HPV vaccination campaign. Out of the 157 comments, we judged 52 (33%) of them to be ‘hesitant’, suggesting that people with negative reactions though few in number, were more likely to be vocal deniers. Concern around the safety of HPV vaccines including effects on reproductive health was the most common theme identified. Other emerging themes included: risk of cervical cancer perceived as being low, issues around consent, concerns that girls are being used for research, questionable vaccine effectiveness, use of the school-based strategy for the campaign, risk-benefits calculations of HPV vaccination and constraints such as stock-outs. Knowing someone who had been affected or being at risk of cervical cancer, having knowledge about the causes of cervical cancer, confidence in the effectiveness and safety of the vaccine, knowing the vaccine was being used in high income settings, and having strong recommendations from the World Health Organisation and key actors seemed to increase the willingness to accept the vaccine. The magnitude and causes of HPV vaccine hesitancy need to be investigated to ensure the success of this programme. 相似文献

ObjectiveTo determine whether providers’ vaccine recommendation style affects length of the adolescent vaccine discussions.MethodsWe analyzed vaccine discussions using audio-recordings of clinical encounters where adolescents were eligible for HPV vaccines ± meningococcal vaccines. We measured length of vaccine discussions, the provider’s use of an “indicated” (vaccination due at visit) or “elective” (vaccination is optional) recommendation style, and vaccine receipt. Parent and child demographics, parental vaccination intentions, and parental satisfaction with vaccine discussion were collected from pre- and post-visit surveys. We used linear and logit regressions with random effects to estimate recommendation style’s association with discussion length and with vaccine receipt, respectively.ResultsWe analyzed 106 vaccine discussions (82 HPV; 24 meningococcal) across 82 clinical encounters and 43 providers. Vaccine discussions were longer when providers presented vaccination as elective versus indicated (140 vs. 74 s; p-value < 0.001). Controlling for vaccine type, parental vaccination intent, and patient characteristics, an elective style was associated with 41 seconds longer vaccine discussion (p-value < 0.05). Providers used the indicated style more frequently with the meningococcal vaccine than with the HPV vaccine (96% vs. 72%; p-value < 0.05). Parents’ odds of vaccinating were 9.3 times higher following an indicated versus an elective presentation (p-value < 0.05). Vaccine discussion length and presentation style were not associated with parental satisfaction.ConclusionsOur results suggest that using an indicated recommendation improves vaccine discussions’ efficiency and effectiveness, but this style is used more often with meningococcal than HPV vaccines. Increasing providers’ use of indicated styles for HPV vaccines has the potential to increase vaccination rates and save time during medical visits. 相似文献

IntroductionAustralia’s novel, active surveillance system, AusVaxSafety, monitors the post-market safety of vaccines in near real time. We analysed cumulative surveillance data for children aged 6 months to 4 years who received seasonal influenza vaccine in 2015 and/or 2016 to determine: adverse event following immunisation (AEFI) rates by vaccine brand, age and concomitant vaccine administration.MethodsParent/carer reports of AEFI occurring within 3 days of their child receiving an influenza vaccine in sentinel immunisation clinics were solicited by Short Message Service (SMS) and/or email-based survey. Retrospective data from 2 years were combined to examine specific AEFI rates, particularly fever and medical attendance as a proxy for serious adverse events (SAE), with and without concomitant vaccine administration. As trivalent influenza vaccines (TIV) were funded in Australia’s National Immunisation Program (NIP) in 2015 and quadrivalent (QIV) in 2016, respectively, we compared their safety profiles.Results7402 children were included. Data were reported weekly through each vaccination season; no safety signals or excess of adverse events were detected. More children who received a concomitant vaccine had fever (7.5% versus 2.8%; p < .001). Meningococcal B vaccine was associated with the highest increase in AEFI rates among children receiving a specified concomitant vaccine: 30.3% reported an AEFI compared with 7.3% who received an influenza vaccine alone (p < .001). Reported fever was strongly associated with medical attendance (OR: 42.6; 95% Confidence Interval (CI): 25.6–71.0). TIV and QIV safety profiles included low and expected AEFI rates (fever: 4.3% for TIV compared with 3.2% for QIV (p = .015); injection site reaction: 1.9% for TIV compared with 3.0% for QIV (p < .001)). There was no difference in safety profile between brands.DiscussionActive participant-reported data provided timely vaccine brand-specific safety information. Our surveillance system has particular utility in monitoring the safety of influenza vaccines, given that they may vary in composition annually. 相似文献

IntroductionZero-dose prevalence refers to children who failed to receive any routine vaccination. Little is known about the “immunisation cascade” in low- and middle-income countries (LMICs), defined as how children move from zero dose to full immunisation.MethodsUsing data from national surveys carried out in 92 LMICs since 2010 and focusing on the four basic vaccines delivered in infancy (BCG, polio, DPT and MCV), we describe zero-dose prevalence and the immunisation cascade in children aged 12 to 23 months. We also describe the most frequent combinations of vaccines (or co-coverage) among children who are partially immunized. Analyses are stratified by country income groups, household wealth quintiles derived from asset indices, sex of the child and area of residence. Results were pooled across countries using child populations as weights.ResultsIn the 92 countries, 7.7% were in the zero-dose group, and 3.3%, 3.4% and 14.6% received one, two or three vaccines, respectively; 70.9% received the four types and 59.9% of the total were fully immunised with all doses of the four vaccines. Three quarters (76.8%) of children who received the first vaccine received all four types. Among children with a single vaccine, polio was the most common in low- and lower-middle income countries, and BCG in upper-middle income countries. There were sharp inequalities according to household wealth, with zero-dose prevalence ranging from 12.5% in the poorest to 3.4% in the wealthiest quintile across all countries. The cascades were similar for boys and girls. In terms of dropout, 4% of children receiving BCG did not receive DPT1, 14% receiving DPT1 did not receive DPT3, and 9% receiving DPT3 did not progress to receive MCV.Interpretation.Focusing on zero-dose children is particularly important because those who are reached with the first vaccine are highly likely to also receive remaining vaccines. 相似文献

BackgroundTo minimise vaccine-associated risk of intussusception following rotavirus vaccination, Norway adopted very strict age limits for initiating and completing the vaccine series at the time rotavirus vaccination was included in the national immunisation programme, October 2014. Although Norway has a high coverage for routine childhood vaccines, these stringent age limits could negatively affect rotavirus coverage. We documented the status and impact of rotavirus vaccination on other infant vaccines during the first year after its introduction.MethodsWe used individual vaccination data from the national immunisation register to calculate coverage for rotavirus and other vaccines and examine adherence with the recommended schedules. We identified factors associated with completing the full rotavirus series by performing multiple logistic regression analyses. We also evaluated potential changes in uptake and timeliness of other routine vaccines after the introduction of rotavirus vaccine using the Kaplan-Meier method.ResultsThe national coverage for rotavirus vaccine achieved a year after the introduction was 89% for one dose and 82% for two doses, respectively. Among fully rotavirus-vaccinated children, 98% received both doses within the upper age limit and 90% received both doses according to the recommended schedule. The child’s age at the initiation of rotavirus series and being vaccinated with diphtheria, tetanus, pertussis, polio and Haemophilus influenzae type b (DTaP/IPV/Hib) and pneumococcal vaccines were the strongest predictors of completing the full rotavirus series. No major changes in uptake and timeliness of other paediatric vaccines were observed after introduction of rotavirus vaccine.ConclusionsNorway achieved a high national coverage and excellent adherence with the strict age limits for rotavirus vaccine administration during the first year of introduction, indicating robustness of the national immunisation programme. Rotavirus vaccination did not impact coverage or timeliness of other infant vaccines. 相似文献

BackgroundMaternal immunisation is important to protect both mother and baby, but safety concerns can lead to low uptake. AusVaxSafety participant-based surveillance actively monitors adverse events following immunisation (AEFI) in Australia. We aimed to analyse AEFI in the days following vaccination with seasonal inactivated influenza vaccine (IIV) and/or reduced antigen diphtheria-tetanus-acellular pertussis vaccine (dTpa) in pregnant women in Australia.MethodsDe-identified AEFI reports were solicited from vaccine recipients via automated SMS survey (using SmartVax software) following routine vaccination with IIV and/or dTpa at 219 national sentinel surveillance sites from 2015 to 2018. AEFI rates were compared by vaccine group (IIV alone, dTpa alone, or IIV and dTpa together), vaccine brand, trimester (IIV only) and vaccination period (April to August 2016–2018; IIV only). Women who had two vaccination encounters during surveillance were identified and AEFI rates compared for each dose.ResultsAmong 13,758 participants, overall AEFI rates were lower following IIV (4.9%) than dTpa (6.4%) or IIV and dTpa given concomitantly (7.4%). The AEFI profile was similar for both vaccines, with injection site reactions, tiredness, and headache most commonly reported. Injection site pain and swelling/redness were significantly more common in women who received dTpa than IIV. Reports of medical attendance following immunisation were similar (0.3%) for each vaccine group. AEFI rates did not differ by IIV brand (FluQuadri®, Fluarix® Tetra), dTpa brand (Boostrix®, Adacel®), or by trimester. Among women with sequential dTpa vaccinations, 6.0% (7/116) had an AEFI following their second dTpa dose.ConclusionsSelf-reported AEFI rates did not differ by trimester (IIV), or by vaccine brand (IIV or dTpa). Concomitant influenza and pertussis vaccination was associated with more frequent, but low rates of minor, expected AEFI. These real world ‘citizen science-based’ data provide further reassuring evidence of the safety of maternal vaccination. 相似文献

BackgroundGenital human papillomavirus (HPV) infection is the most prevalent sexually transmitted infection among young adults ages 15–25 years in the United States (US). Although HPV vaccines are recommended for individuals ages through 26 years, vaccine completion rates remain substantially low.MethodsAccordingly, our study utilized a comprehensive – Theoretical Domains Framework (TDF) of behavior change to systematically identify facilitators and barriers to catch-up HPV vaccinations. Five databases - Medline, Embase, CINAHL, ERIC, and PsycINFO were searched from January 2009 to July 2019 for empirical studies using quantitative and qualitative methods to assess HPV vaccine uptake among males ages 18–26 years within US college and university settings. The TDF analytic process included a content analysis using the mixed deductive-inductive approach to extract, analyze and categorize data into TDF domains/themes and sub-themes.ResultsOverall, 17 studies were selected for data extraction. We identified eleven key TDF domains that influenced HPV vaccination behavior among college male students: ‘knowledge’ (82% of included studies), ‘environmental context and resources’ (53%), ‘beliefs about consequences’ (53%), ‘unrealistic optimism’ (50%) and ‘pessimism’ (6%), ‘emotion’ (50%), ‘social influences’ (50%), ‘beliefs about capabilities’ (41%), ‘intention’ (24%), ‘reinforcement’ (18%), ‘social professional role and identity’(12%), and ‘behavioral regulation’ (12%). Barriers influencing HPV vaccine uptake included lack of knowledge and awareness regarding HPV infections, HPV vaccine safety, effectiveness, side effects, and costs; absence of health providers’ recommendations; lack of healthcare and health insurance; low levels of perceived susceptibility and severity for HPV infections; HPV vaccine misinformation; as well as social stigma and peer influences regarding HPV vaccinations. Enablers for HPV vaccine uptake included high levels of perceived benefits for HPV vaccines.DiscussionOur study theoretically identified factors influencing HPV vaccinations. This could inform the efficient planning, support, and implementation of interventions that facilitate catch-up HPV vaccination practices among high-risk males within college/university settings. 相似文献

BackgroundHong Kong experiences year-round influenza activity with winter and summer peaks. The government’s Vaccination Subsidy Scheme (VSS) provides vaccine to high-risk groups prior to the larger winter peak. The VSS is predominantly administered through the private sector. This study aimed to cost the two theoretical routine influenza vaccination schedules using both northern and southern hemisphere vaccines, administered according to child’s age and women’s gestation, from a governmental perspective; and compare these costs to the costs of government’s seasonal VSS assuming equivalent coverage estimates to determine the budget impacts of these influenza vaccination programmes in Hong Kong.MethodsWe used the World Health Organization’s Flutool Plus to estimate the incremental annual costs for immunising young children aged 6 months to 2 years and pregnant women with influenza vaccine during 2021, assuming the latter group accesses the public system for some antenatal care. Inputs were based on literature review, publicly available data and expert opinions. Sensitivity analyses were done with various coverage rates and vaccine costs.ResultsThe annual incremental cost (including vaccine price) to vaccinate young children with three doses of influenza vaccine during the first two years of life was estimated at USD 1,175,146 (per-dose-cost of USD 10.55) at 75% coverage while that to vaccinate pregnant women with one dose at 60% coverage was estimated at USD 398,555 (per-dose-cost of USD 13.39). Across a range of sensitivity analyses we predict that routine year-round schedules could be cost-saving to the government compared to the VSS. Implementing routine immunisation to both risk groups equates to USD 1,573,701, i.e., 0.012% of Hong Kong’s annual healthcare spending.ConclusionProposed year-round universal schedules providing influenza immunisation according to the child’s age or the woman’s gestation are predicted to be cost-saving compared to the current seasonally administered subsidised vaccine programme. 相似文献
