A qualitative study of vaccination behaviour amongst female Polish migrants in Edinburgh,Scotland

Vaccine hesitancy is increasing and failure to vaccinate is well-recognised in Europe as a contributing factor to outbreaks of infectious diseases. In Lothian and Scotland, low vaccine uptake has been seen in migrants – notably in the Polish group who have arrived since 2004. The recent Vaccine Confidence in European Union report highlights a concerning recent decline in vaccine confidence in Poland.We held three focus groups containing 13 Polish women about the childhood vaccination programme in Lothian, with specific focus on influenza and Human Papillomavirus vaccinations. Key emergent themes were: trust in the national vaccination policy, trust in the vaccination providers (health professionals), trust in the individual vaccines, balancing the risk of disease, and language and communication.Polish norms, beliefs and behaviours shape how Polish migrants navigate the UK health system and its vaccination programme. While not confident in the Scottish primary care model and its generalist practitioners, the participants liked the ethos of informed consent in Scotland and compared this favourably with the compulsory vaccination policy in Poland. There was a belief that vaccines in Scotland were of higher quality than Poland and with fewer adverse effects.Respondents reported returning to Poland for specialist clinical appointments and diagnostic testing. They regularly access Polish clinical expertise and their opinions about health are influenced by Polish friends and family. They say they have difficulty finding official UK Government and health authority vaccination material and often access Polish media, online resources and information. They are familiar with anti-vaccination activities in Poland.Consequently, there are important unmet information needs for this group of parents who may not be making truly informed choices about vaccination. This requires further investigation especially as migration continues and declining immunisation uptake is reported in many countries across Europe.     

Health risk communication and amplification: learning from the MMR vaccination controversy

Immunisation is the cornerstone of childhood disease prevention. In this context the combined measles, mumps and rubella vaccination (MMR) has proved a world-wide success, although in the UK it has been at the centre of public controversy since 1998. Through the media, the public domain has witnessed contestation among expert views about the relative risks associated with the diseases vs. the potential side-effects of the vaccination. Attainment of health protection targets has been compromised. The UK Department of Health sought to redress this through a major communication exercise. This paper reports the findings of a study of information strategies that parents use to make sense of health risk issues, particularly MMR. The findings identify the importance of social networks in reinforcing parental understanding and beliefs. While the media are identified as important sources of information, there is no evidence to suggest that parents passively receive and act upon such risk messages. Official information has been able to capitalise on the strong social normalisation of vaccination, but has not responded fully to the evolving social interpretation of risks. The study reveals a preference for personal and face-to-face engagement with health professionals, stressing the importance of user-centred health risk communication.     

Estimating vaccination coverage: validity of household-retained vaccination cards and parental recall

Public health programs rely on household-survey estimates of vaccination coverage as a basis of programmatic and policy decisions; however, the validity of estimates derived from household-retained vaccination cards and parental recall has not been thoroughly evaluated. Using data from a vaccination coverage survey conducted in the Western Pacific's Northern Mariana Islands, we compared results from household data sources to medical record sources for the same children. We calculated the percentage of children aged 1, 2, and 6 years who received all vaccines recommended by age 12 months, 24 months, and for school entry, respectively. Coverage estimates based on vaccination cards ranged from 14% to 30% in the three age groups compared to 78-91% for the same children based on medical records. When cards were supplemented by parental recall, estimates were 51-53%. Concordance, sensitivity, specificity, positive and negative predictive values, and kappa statistics generally indicated poor agreement between household and medical record sources. Household-retained vaccination cards and parental recall were insufficient sources of information for estimating vaccination coverage in this population. This study emphasizes the importance of identifying reliable sources of vaccination history information and reinforces the need for awareness of the potential limitations of vaccination coverage estimated from surveys that rely on household-retained cards and/or parental recall.     

Facilitators and barriers of parental attitudes and beliefs toward school-located influenza vaccination in the United States: Systematic review

The study objective was to identify facilitators and barriers of parental attitudes and beliefs toward school-located influenza vaccination in the United States. In 2009, the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention expanded their recommendations for influenza vaccination to include school-aged children. We conducted a systematic review of studies focused on facilitators and barriers of parental attitudes toward school-located influenza vaccination in the United States from 1990 to 2016. We reviewed 11 articles by use of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework. Facilitators were free/low cost vaccination; having belief in vaccine efficacy, influenza severity, and susceptibility; belief that vaccination is beneficial, important, and a social norm; perception of school setting advantages; trust; and parental presence. Barriers were cost; concerns regarding vaccine safety, efficacy, equipment sterility, and adverse effects; perception of school setting barriers; negative physician advice of contraindications; distrust in vaccines and school-located vaccination programs; and health information privacy concerns. We identified the facilitators and barriers of parental attitudes and beliefs toward school-located influenza vaccination to assist in the evidence-based design and implementation of influenza vaccination programs targeted for children in the United States and to improve influenza vaccination coverage for population-wide health benefits.     

Factors underlying parental decisions about combination childhood vaccinations including MMR: A systematic review

Suboptimal childhood vaccination uptake results in disease outbreaks, and in developed countries is largely attributable to parental choice. To inform evidence-based interventions, we conducted a systematic review of factors underlying parental vaccination decisions. Thirty-one studies were reviewed. Outcomes and methods are disparate, which limits synthesis; however parents are consistently shown to act in line with their attitudes to combination childhood vaccinations. Vaccine-declining parents believe that vaccines are unsafe and ineffective and that the diseases they are given to prevent are mild and uncommon; they mistrust their health professionals, Government and officially-endorsed vaccine research but trust media and non-official information sources and resent perceived pressure to risk their own child's safety for public health benefit. Interventions should focus on detailed decision mechanisms including disease-related anticipated regret and perception of anecdotal information as statistically representative. Self-reported vaccine uptake, retrospective attitude assessment and unrepresentative samples limit the reliability of reviewed data – methodological improvements are required in this area.     

Perceptions of vaccination within a Christian homeschooling community in Pennsylvania

BackgroundMore than 1.8 million American children ages 5–17 are being educated at home. The percentage of school-aged children in the United States who are homeschooled increased from 1.7% in 1999 to 3.4% in 2012. Every state has established school-entry vaccination requirements for kindergarten students, but most states exempt homeschoolers from these regulations. The goal of this study was to use qualitative methods to examine the vaccination perceptions and practices of Christian homeschooling families in Pennsylvania.MethodsA qualitative study (focus groups) of Christian homeschooling parents representing a diversity of vaccination practices (full, partial/delayed, and no vaccination) was conducted in south-central Pennsylvania in 2017. An analysis using a grounded theory approach identified themes that strongly aligned with constructs from the Health Belief Model.ResultsMany of the perspectives expressed by the study population aligned with those of the general American population, including uncertainty about the risk from vaccine-preventable diseases, concerns about the efficacy and safety of vaccines, and confusion about conflicting vaccine information. The Christian homeschooling parents expressed two especially prominent perceptions: a belief that they had a very low risk of contracting infectious diseases because God has provided them with the natural tools necessary for health and a stronger-than-typical sense of empowerment related to parental decision-making and autonomy. Participants expressed that they were generally open to honest communication about vaccination with physicians who respect parental authority.ConclusionsHomeschooling families have diverse vaccination practices. Pediatricians and other healthcare practitioners should not make assumptions about health beliefs in this community, and should instead engage parents in conversations about their risk perceptions and vaccine decisions.     

Confidence in vaccination: a parent model

Although vaccination has been heralded as one of the 10 greatest public health achievements, how parents differ in their views about vaccination is not well understood. A deeper understanding of these attitudes and beliefs may improve the effectiveness of vaccine communications. In this mailed survey of U.S. parents in January 2001 (return response rate 49%), parental confidence in vaccination was very high, although there was significant variation among parents. Using multivariate analyses to group and profile parents, 90% of parents (n=1820) were classified into one of four distinct parent groups: (1) "Vaccine Believer" parents who were convinced of the benefit of vaccination; (2) "Cautious" parents noteworthy for a high emotional investment in their child; (3) "Relaxed" parents characterized by a less involved parenting style and some skepticism about vaccines; and (4) "Unconvinced" parents distinguished by their distrust of vaccinations and vaccination policy. These findings suggest that messages that are customized to parents' attitudes and beliefs may improve their understanding and acceptance of vaccination.     

Trust and the development of health care as a social institution

Health systems are inherently relational and so many of the most critical challenges for health systems are relationship and behaviour problems. Yet the disciplinary perspectives that underlie traditional health policy analysis offer only limited and partial insights into human behaviour and relationships. The health sector, therefore, has much to learn from the wider literature on behaviour and the factors that influence it. A central feature of recent debates, particularly, but not only, in relation to social capital, is trust and its role in facilitating collective action, that is co-operation among people to achieve common goals. The particular significance of trust is that it offers an alternative approach to the economic individualism that has driven public policy analysis in recent decades. This paper considers what the debates on trust have to offer health policy analysis by exploring the meaning, bases and outcomes of trust, and its relevance to health systems. It, first, presents a synthesis of theoretical perspectives on the notion of trust. Second, it argues both that trust underpins the co-operation within health systems that is necessary to health production, and that a trust-based health system can make an important contribution to building value in society. Finally, five conclusions are drawn for an approach to health policy analysis that takes trust seriously.     

Attitudes towards mandatory vaccination and sanctions for vaccination refusal

AimsInvestigating attitudes towards mandatory vaccination and sanctions for vaccination refusal in an area with insufficient vaccination coverage may help health authorities to assess which strategies for increasing vaccination coverage are appropriate. This study examines attitudes to vaccine mandates and asks questions regarding what kinds of sanctions could legitimately result from vaccination refusal. It seeks to find out if people’s attitudes towards mandates and towards sanctions for vaccination refusal are related to their attitudes to vaccines and the degree of trust they feel towards health care professionals and health care authorities. The study also discusses how the observed attitudes towards mandates may be related to perceptions of autonomy, responsibility, and equitability.MethodsData collection was carried out in Finland through an online survey in a region with suboptimal vaccine uptake. Statistical analysis was conducted on a sample of 1101 respondents, using confirmatory factor analysis and structural regression analysis.ResultsPersons hold different views on mandates and sanctions. Importantly, the persons who support vaccination mandates and sanctions for vaccination refusal are to a great degree the same people who have positive attitudes to vaccines and high trust in health care professionals and health authorities.ConclusionTrust is a key factor which has a bearing on people’s attitudes towards mandates and sanctions for noncompliance. A focus on the reasons for lack of trust, and on how to enhance trust, is a more feasible long-term way (than mandates) to promote large- scale compliance with childhood vaccine programmes in the studied country context.     

Changing livestock vaccination policy alters the epidemiology of human anthrax,Georgia, 2000–2013

Anthrax is a widely spread zoonotic disease found on nearly every continent. To control the disease in humans and animals, annual livestock vaccination is recommended. However, in 2007, the country of Georgia ended its policy of compulsory annual livestock anthrax vaccination. Our objective was to assess how the epidemiology of human anthrax has evolved from 2000–2013 in Georgia, in the wake of this cessation. We used passive surveillance data on epidemiological surveys of human anthrax case patients. Risk factors and rates of self-reported sources of infection were compared, before and after the change in livestock vaccination policy. We mapped ethnicity-adjusted incidence during the two periods and assessed changes in the spatial pattern of risk. The overall risk of human anthrax increased >5-fold, from 0.7 cases per 100,000 in 2000 to 3.7 cases per 100,000 by 2013. Ethnic disparities in risk became pronounced; from 2000 to 2013, incidence increased >60-fold in Azerbaijanis from 0.35 to 21.1 cases/100,000 Azerbaijanis compared to 0.61 to 1.9 cases/100,000 among ethnic Georgians. Food-borne exposures from purchasing meat increased from 11% in 2000–2006 to 21% in 2007–2013. Spatial analyses revealed a shift from a random pattern of reporting pre-policy change to clustering among district municipalities following the change in policy. Our findings indicate there were unintended human health consequences associated with changing livestock vaccination policy. Following a reduction in the immunizations administered, there was a major shift in the epidemiology of human anthrax in Georgia. Current infection risk is now highest among ethnic minorities. Increased reporting among individuals uncharacteristically at risk for anthrax from foodborne exposures suggests spillover from modes of agricultural production. Given the importance of human-livestock health linkages, careful evaluations of policy need to be undertaken before changes to animal vaccination are made.     

Civil society: a critical new advocate for vaccination in Europe

The vaccinology landscape has changed, with national authorities now being increasingly accountable to new stakeholders such as health insurers, regional regulatory bodies, the media, and civil society. Here, we discuss how civil society organisations (CSOs), such as patient and women's groups, have become important drivers in the introduction and sustainability of new vaccination programs. This shift in public implication in vaccine policy has been well illustrated in the recent introduction of human papillomavirus (HPV) vaccination in Europe. Patient and women's groups which were traditionally focused on advocacy of treatments have also become advocates for prevention with the advent of HPV vaccination. Civil society advocacy at the European level supported key resolutions and white papers which in turn informed national recommendations on cervical cancer vaccination. CSOs were also active at the national level, supporting national policy makers. These organisations may bring innovative and effective new approaches to communication on vaccination benefits, using public events, celebrities and various social media. Working with experts, CSOs can also be an important bridge from the science to the lay public. This may provide a vital counterbalance to media hype and antivaccination groups, although CSOs may also be active and vocal opponents of immunization. The successful implementation and sustainability of future vaccination programs against infections such as HIV will be dependent upon the active participation of civil society to inform, to reassure and to maintain public trust.     

‘I trust them because my mum trusts them’: Exploring the role of trust in HPV vaccination decision-making among adolescent girls and their mothers in France

The success of vaccination programmes relies on high uptake and acceptance of vaccines, which is in part influenced by public trust in vaccines, providers, policy-makers and information. France is one of the countries in the world with the lowest confidence in vaccination, with parents expressing particular concerns about the human papillomavirus (HPV) vaccine. This qualitative study explored the role of trust in HPV vaccination decision-making among mothers and adolescent girls in France. Semi-structured interviews and focus groups were conducted with 15–16-year-old adolescent girls and their mothers in Paris. A thematic analysis based on deductive and inductive coding was conducted. HPV vaccination decision-making was described as a complex and uncertain process, a possible consequence of erosion of trust in the vaccine, in healthcare professionals and health authorities, and in information itself. Due to public criticism of the vaccine and conflicting advice received from medical professionals, the vaccine was perceived as controversial. The mothers’ strong trust in doctors did not always increase HPV vaccine acceptance, as doctors themselves failed to recommend or recommended against the vaccine. Furthermore, the perceived mismanagement of previous health events tainted the mothers’ trust in health authorities. Contrastingly, while adolescents expressed trust in doctors and health authorities, their trust in their own mothers was stronger. A lack of exposure to positive sources of information (e.g. from doctors, schools or media) contributed to low awareness about HPV vaccination among adolescent girls. While both mothers and girls discussed the importance of trusting themselves, they also acknowledged being influenced by others around them as well as information, often negative, from the internet. Adolescent girls also expressed mistrust about information in general, explaining that any information can be manipulated. Low confidence in HPV vaccination in France can be explained by broader trust issues, which will require long-term efforts to address.     

The significance of folklore for vaccine policy: discarding the deficit model

This paper addresses the relevance of medical folklore for vaccine policy intended to increase vaccination uptake. There are two primary claims of this paper: First, that dominant approaches to increasing US vaccination uptake have largely been based on deficient understandings of the root causes of anti-vaccination behavior; and second, that superior approaches to evidence-based policy must enlarge the scope of that evidence base to include crucial findings on belief formation, technical, and risk communication, and the folklore of vaccination. The failure to attend to this evidence results in interventions that are disconnected from the factors actually driving vaccination refusal. The paper describes the deficiencies in dominant approaches, and based on its analysis of the root causes of anti-vaccination behavior recommends superior evidence-based policies that emphasize upstream structural determinants of health behaviors.     

Hepatitis B vaccination: the cost effectiveness of alternative strategies in England and Wales.

OBJECTIVE--To assess the cost effectiveness of adding universal hepatitis B vaccination in infancy or pre-adolescence to a policy of selective vaccination of at risk groups. DESIGN--Costs of a selective policy and additional costs of universal vaccination policies were estimated from costs of vaccine delivery and published data on target populations. Additional years of life gained were calculated for each policy by applying life tables to estimates of mortality attributable to hepatitis B. SETTING--England and Wales. RESULTS--Compared with no vaccination, vaccination in infancy was the most cost effective followed by vaccination in preadolescence. Selective vaccination was the least effective (cost per year of life gained 2568 pounds, 2824 pounds, and 8564 pounds respectively). Adding vaccination in infancy or at pre-adolescence to a selective policy cost 1537 pounds or 1658 pounds per year of life gained. Discounting years gained in the future at 6% per annum, however, made pre-adolescent vaccination more cost effective than infant or selective vaccination (51,817 pounds, 94,821 pounds, and 124,779 pounds per discounted year of life gained). Adding pre-adolescent vaccination to a selective policy cost 32,125 pounds per discounted year of life gained and infant vaccination, 77,085 pounds. CONCLUSIONS--Universal vaccination against hepatitis B was more cost effective than selective vaccination in a low prevalence country. Discounting future health gain, however, made universal infant vaccination lest cost effective than universal pre-adolescent vaccination. If future health gained is as important as present gain the addition of universal vaccination to a selective policy is equivalent to the cost per quality adjusted year of life from renal transplantation or breast cancer screening.     

Human papillomavirus (HPV) vaccination in the transition between adolescence and adulthood

PurposeYoung adulthood is characterized by changes in health care decision-making, insurance coverage, and sexual risk. Although the human papillomavirus (HPV) vaccine is now approved for adults up to age 45, and catch-up vaccination is currently recommended up through age 26, vaccination rates remain low in young adults. This study explored perspectives on HPV vaccination among young adults receiving care at the student health center of a large public university.MethodsWe conducted semi-structured interviews (n = 27) and four focus groups with female and male undergraduate and graduate students (n = 18) and semi-structured interviews with health care providers (n = 6). Interviews and focus groups explored perceived risk of HPV infection, benefits of the HPV vaccine, and motivations for and barriers to HPV vaccination.ResultsMany young adults cited their parents’ views and recommendations from medical providers as influential on their decision-making process. Students perceived that cervical cancer prevention was a main benefit of the HPV vaccine and sexual activity was a risk factor for HPV infection. Students often lacked knowledge about the vaccine’s benefits for males and expressed some concerns about the safety and side effects of a vaccine perceived as new. Logistical barriers to vaccination included uncertainty over vaccination status and insurance coverage for the vaccine, and concerns about balancing the vaccine schedule with school obligations. Providers’ vaccine recommendations were impacted by health system factors, including clinical infrastructure, processes for recommending and documenting vaccination, and office visit priorities. Suggested vaccination promotion strategies included improving the timing and messaging of outreach efforts on campus and bolstering clinical infrastructure.ConclusionsAlthough college may be an opportune time to reach young adults for HPV vaccination, obstacles including navigating parental influence and independent decision-making, lack of awareness of vaccination status, and numerous logistical and system-level barriers may impede vaccination during this time.     

Does corruption undermine trust in health care? Results from public opinion polls in Croatia

Health and health care provision are one of the most important topics in public policy, and often a highly debated topic in the political arena. The importance of considering trust in the health care sector is highlighted by studies showing that trust is associated, among others, with poor self-related health, and poorer health outcomes. Similarly, corruption has shown to create economic costs and inefficiencies in the health care sector. This is particularly important for a newly democratized country such as Croatia, where a policy responsive government indicates a high level of quality of democracy (Roberts, 2009) and where a legacy of corruption in the health care sector has been carried over from the previous regime. In this study, I assess the relationship between health care corruption and trust in public health care and hypothesize that experience with health care corruption as well as perception of corruption has a negative effect on trust in public care facilities. Data were collected in two surveys, administered in 2007 and 2009 in Croatia. Experience with corruption and salience with corruption has a negative effect on trust in public health care in the 2007 survey, but not in the 2009 survey. While the results are mixed, they point to the importance of further studying this relationship.     

Public vaccination programmes against hepatitis B in The Netherlands: assessing whether a targeted or a universal approach is appropriate

To date, the policy to control hepatitis B in the Netherlands is to vaccinate specific risk groups, rather than all children. Low incidence of the disease has fueled debate whether such a targeted vaccination strategy or rather a universal strategy, as recommended by the World Health Organization, is appropriate. The standard framework for assessing whether a particular vaccination should be included in a public programme, as recently proposed by the Health Council of the Netherlands (HCN), was applied to the various options for hepatitis B vaccination. This framework includes seven selection criteria, grouped under five thematic headings: seriousness and extent of the disease burden, effectiveness and safety of the vaccination, acceptability of the vaccination, efficiency of the vaccination, and priority of the vaccination. From about 1990 the disease burden has stayed more or less the same over time and careful assessment has made it clear that the targeted approach has failed to reach a significant part of the risk groups. Models suggest that the public health benefits obtained through targeted programmes could be augmented considerably by universal vaccination. Based on the assessment that universal vaccination means better protection for high-risk groups as well as the whole population, the HCN calls for universal immunisation, even though hepatitis B to a large extent is limited to specific high-risk groups. Should the Netherlands adopt universal vaccination, several immunisation programmes targeted to high-risk groups will, however, remain of crucial importance for years to come.
