Abstract
The immune system's complexity and ongoing evolutionary struggle against deleterious pathogens underscore the value of vaccination technologies, which have been bolstering human immunity for over two centuries. Despite noteworthy advancements over these 200 years, three areas remain recalcitrant to improvement owing to the environmental instability of the biomolecules used in vaccines─the challenges of formulating them into controlled release systems, their need for constant refrigeration to avoid loss of efficacy, and the requirement that they be delivered via needle owing to gastrointestinal incompatibility. Nanotechnology, particularly metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), has emerged as a promising avenue for confronting these challenges, presenting a new frontier in vaccine development. Although these materials have been widely explored in the context of drug delivery, imaging, and cancer immunotherapy, their role in immunology and vaccine-related applications is a recent yet rapidly developing field. This review seeks to elucidate the prospective use of MOFs and COFs for biomaterial stabilization, eliminating the necessity for cold chains, enhancing antigen potency as adjuvants, and potentializing needle-free delivery of vaccines. It provides an expansive and critical viewpoint on this rapidly evolving field of research and emphasizes the vital contribution of chemists in driving further advancements.

Abstract
Over the past two centuries, vaccines have been critical for the prevention of infectious diseases and are considered milestones in the medical and public health history. The World Health Organization estimates that vaccination currently prevents approximately 3.5-5 million deaths annually, attributed to diseases such as diphtheria, tetanus, pertussis, influenza, and measles. Vaccination has been instrumental in eradicating important pathogens, including the smallpox virus and wild poliovirus types 2 and 3. This narrative review offers a detailed journey through the history and advancements in vaccinology, tailored for healthcare workers. It traces pivotal milestones, beginning with the variolation practices in the early 17th century, the development of the first smallpox vaccine, and the continuous evolution and innovation in vaccine development up to the present day. We also briefly review immunological principles underlying vaccination, as well as the main vaccine types, with a special mention of the recently introduced mRNA vaccine technology. Additionally, we discuss the broad benefits of vaccines, including their role in reducing morbidity and mortality, and in fostering socioeconomic development in communities. Finally, we address the issue of vaccine hesitancy and discuss effective strategies to promote vaccine acceptance. Research, collaboration, and the widespread acceptance and use of vaccines are imperative for the continued success of vaccination programs in controlling and ultimately eradicating infectious diseases.

Abstract
Hemorrhagic disease of the newborn, more aptly termed "Vitamin K Deficiency Bleeding (VKDB)," has long been recognized as a cause of significant morbidity and mortality in early infancy. A single intramuscular dose of vitamin K administered at birth has virtually eliminated VKDB, and this prophylactic regimen has been recommended by the American Academy of Pediatrics since 1961. Although most newborns in the United States receive vitamin K at birth, a growing number of parents are hesitant about this intervention, citing concerns about harm from the injection, preservatives contained in the medication, and clashes with personal belief systems. Ultimately, there is distrust in the medical establishment as many of these parents also opt out of newborn ophthalmic prophylaxis and importantly, childhood vaccinations, establishing a dangerous public health precedent that will lead to resurgence of vaccine-preventable diseases. Various shared decision making models and educational efforts can assist newborn health care professionals in addressing these parental concerns so that VKDB can be effectively prevented in all newborns.

Why Parents Say No to Having Their Children Vaccinated against Measles: A Systematic Review of the Social Determinants of Parental Perceptions on MMR Vaccine Hesitancy. Vaccines (Basel) 2023; 11:vaccines11050926. [PMID: 37243030 DOI: 10.3390/vaccines11050926] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 04/20/2023] [Accepted: 04/24/2023] [Indexed: 05/28/2023] Open
Abstract
Ongoing outbreaks of measles threaten its elimination status in the United States. Its resurgence points to lower parental vaccine confidence and local pockets of unvaccinated and undervaccinated individuals. The geographic clustering of hesitancy to MMR indicates the presence of social drivers that shape parental perceptions and decisions on immunization. Through a qualitative systematic review of published literature (n = 115 articles; 7 databases), we determined major themes regarding parental reasons for MMR vaccine hesitancy, social context of MMR vaccine hesitancy, and trustworthy vaccine information sources. Fear of autism was the most cited reason for MMR hesitancy. The social drivers of vaccine hesitancy included primary care/healthcare, education, economy, and government/policy factors. Social factors, such as income and education, exerted a bidirectional influence, which facilitated or hindered vaccine compliance depending on how the social determinant was experienced. Fear of autism was the most cited reason for MMR hesitancy. Vaccine hesitancy to MMR and other childhood vaccines clustered in middle- to high-income areas among mothers with a college-level education or higher who preferred internet/social media narratives over physician-based vaccine information. They had low parental trust, low perceived disease susceptibility, and were skeptical of vaccine safety and benefits. Combating MMR vaccine misinformation and hesitancy requires intersectoral and multifaceted approaches at various socioecological levels to address the social drivers of vaccine behavior.

Abstract
Widespread uptake of COVID-19 vaccination is vital to curtailing the pandemic, yet rates remain suboptimal in the U.S. Vaccine mandates have previously been successful, but are controversial. An April 2021 survey of a nationally representative sample (N = 1208) examined vaccine uptake, attitudes, and sociodemographic characteristics. Sixty-seven percent were vaccine acceptors, 14% wait-and-see, and 19% non-acceptors. Compared to wait-and-see and non-acceptors, acceptors were more likely to have a household member over age 65, have received a flu shot, have positive COVID-19 vaccine attitudes, and view COVID-19 vaccination as beneficial. Mandate support was higher among respondents who were vaccine acceptors, had positive views about COVID-19 vaccines, believed in COVID-19 preventive strategies, perceived COVID-19 as severe, were liberal, resided in the Northeast, were non-White, and had incomes < $75,000. Public health campaigns should target attitudes that appear to drive hesitancy and prepare for varying mandate support based on demographics, COVID-19 vaccine attitudes, and the scope of the mandate.

Attitudes of University Students towards Mandatory COVID-19 Vaccination Policies: A Cross-Sectional Survey in Rome, Italy. Vaccines (Basel) 2023; 11:vaccines11040721.

Abstract
Mandatory vaccination (MV) against COVID-19 is a contentious topic. In this study, we used logistic regression models to identify attitudes among Sapienza University students towards MV for COVID-19. We considered three different scenarios: mandatory COVID-19 vaccination (MCV) for healthcare workers (HCWs) (Model 1), for all people aged ≥ 12 years (Model 2), and for admission to schools and universities (Model 3). We collected 5287 questionnaires over a six-month period and divided these into three groups (September-October 2021, November-December 2021, and January-February 2022). MCV for HCWs was the most strongly supported policy (69.8% in favour), followed by MCV for admission to schools and universities (58.3%), and MCV for the general population (54.6%). In a multivariable analysis, the models showed both similarities and differences. There was no association of socio-demographic characteristics with the outcomes, apart from being enrolled in non-healthcare courses, which negatively affected Models 2 and 3. A greater COVID-19 risk perception was generally associated with a more positive attitude towards MCV, although heterogeneously across models. Vaccination status was a predictor of being in favour of MCV for HCWs, whereas being surveyed in November-February 2022 favoured MCV for admission to schools and universities. Attitudes towards MCV were variable across policies; thus, to avoid unintended consequences, these aspects should be carefully considered by policymakers.

Abstract
OBJECTIVES We sought to identify associations between the experience of traumatic life events and vaccination intention to inform whether trauma-affected individuals require targeted interventions when addressing vaccine hesitancy. STUDY DESIGN We conducted an online cross-sectional survey to identify whether direct or indirect exposure to various traumatic life events and the presence of post-traumatic stress disorder (PTSD) symptoms are associated with willingness to receive a COVID-19 vaccine in an Australian sample. METHODS A national online questionnaire was administered to a representative sample of 1050 Australian adults in September 2021. RESULTS Lower willingness to receive a COVID-19 vaccine was associated with direct experience of a fire or explosion (adjusted odds ratio [aOR]: 0.42; 95% confidence interval [CI]: 0.23-0.78; P = 0.006), direct experience of severe human suffering (aOR:0.39; 95% CI: 0.21-0.71; P = 0.002) and screening positive for PTSD symptoms (aOR:0.52; 95% CI: 0.33-0.82; P = 0.005). Conversely, higher willingness to receive a COVID-19 vaccine was associated with indirect exposure to severe human suffering (aOR: 2.0; 95% CI: 1.21-3.22; P = 0.007). CONCLUSIONS Our findings suggest that the experience of traumatic events and the presence of PTSD symptoms can contribute to vaccination decisions. Our work adds to the growing recognition of the need to effectively mediate the influence of traumatic experiences on encounters within the medical setting and supports the importance of addressing the needs of trauma-affected individuals in their vaccination experiences.

Abstract
Vaccination, despite being recognized as one of the most effective primary public health measures, is viewed as unsafe and unnecessary by an increasing number of individuals. Anxiety about vaccines and vaccination programs leading to vaccine hesitancy results from a complex mix of social and political influences, cultural and religious beliefs, the availability of and ability to interpret health and scientific information, and personal and population experiences of health systems and government policies. Vaccine hesitancy is becoming a serious threat to vaccination programs, and was identified as one of the World Health Organization’s top ten global health threats in 2019. The negative impact of anti-vaccination movements is frequently cited as one of the major reasons for rising vaccine hesitancy amongst the general public world-wide. This review discusses the various issues surrounding vaccine hesitancy and the anti-vaccine movement, starting with the definitions of vaccine hesitancy and the anti-vaccine movement in their early history and in the modern era, before discussing the key drivers of vaccine hesitancy, particularly across different regions of the world, with a focus on various countries with low-, middle-, or high-income economies with different socio-economic populations. The review concludes with the impact of vaccine hesitancy on herd immunity and social, psychological, and public health measures to counter vaccine hesitancy.

Abstract
Vaccine hesitancy can hinder the successful roll-out of vaccines. This paper examines COVID-19 vaccine hesitancy in the European Union, drawing from a large-scale cross-national survey covering all 27 EU Member States, carried out between February and March 2021 (n = 29,755). We study the determinants of vaccine hesitancy, focusing on the role of social media use. In multivariate regression models, we find statistically significant (p < 0.05) impacts on vaccine hesitancy of heavy use of social media and using social media as a main source of news. However, the effect of social media and the drivers of vaccine hesitancy vary depending on the reason for hesitancy. Most notably, hesitancy due to health concerns is mainly driven by physical health status and less by social media use, while views that COVID-19 risks are exaggerated (or that COVID-19 does not exist) are more common among men, people in good health, and those using social media as their main source of news.

Abstract
INTRODUCTION Even with the benefits of vaccinations, some parents refuse vaccinations because of the influence of vaccine opponents. The purpose of this article is to identify common vaccine concerns on public forums and address these concerns with scientific evidence, thereby offering pediatric nurse practitioners (PNPs) information on how to respond. METHOD Six electronic databases were searched to identify parental concerns regarding vaccines and provide evidence-based responses to each concern. RESULTS Some parents are concerned that health care providers do not obtain written informed consent before vaccinating their children. Another common concern is that pharmaceutical companies are solely motivated by financial profits when manufacturing vaccines. Parents also share concerns about vaccine manufacturers' exemption from liability for those who suffer a vaccine-related injury. DISCUSSION PNPs are responsible for addressing parents' concerns regarding vaccines and providing the public with correct information. PNPs are in a prime position to influence parental vaccine decision-making positively.

Abstract
International trends currently favour greater use of mandatory immunization. There has been little academic consideration or comparison of the existence and scope of mandatory immunization internationally. In this paper, we examine mandatory immunization in 28 Global NITAG (National Immunization Technical Advisory Group) Network (GNN) countries, including countries from every WHO region and World Bank income level classification. We found that although mandatory immunization programs, or mandatory elements within broader immunization programs, are relatively common, jurisdictions vary significantly with respect to the immunizations required, population groups affected, grounds for exemptions, and penalties for non-compliance. We also observed some loose associations with geography and income level. Based on these data, we categorized policies into a spectrum ranging from Narrow to Broad scope.

Maintaining high vaccination coverage is important in order to protect the individual and the community. Mandatory vaccination is an option in case of declining coverage. Widely used in the USA, it is considered a rather controversial issue in Europe. In Italy, after a decrease of vaccination coverage for the hexavalent and the MPR vaccine under the optimal threshold, a new law, which extended the number of mandatory vaccines from 4 to 10 and reinforced coercive measures, was introduced in July 2017. After 2 years, vaccination coverage increased for all mandatory vaccines and for the other two recommended vaccines (anti-pneumococcal and anti-meningococcal C). Although it is not possible to disentangle the role of other factors contributing to the positive outcome, consistently with the results of studies conducted in the USA, vaccine mandates appeared to be successful in increasing vaccination coverage in Italy. The long-term sustainability of the effect of mandatory vaccination and the potential negative drawbacks of the coercive measures need to be evaluated to generate scientific evidence in public health.

[PMID: 31843271 DOI: 10.1016/j.vaccine.2019.11.073] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2019] [Revised: 11/19/2019] [Accepted: 11/25/2019] [Indexed: 01/17/2023]
Abstract
Vaccines for two viruses which cause cancer, human papillomavirus (HPV) and hepatitis B virus (HBV), are recommended for all children in the United States. Numerous parallels exist between the two vaccines in addition to their roles in cancer prevention, including transmission through sexual contact, multiple doses needed for series completion, and vaccine administration in adolescence for HPV and in the initial phase of the HBV vaccination program. All of these factors were viewed as potential barriers to achieving high rates of coverage, yet the ultimate success of the HBV vaccination program led to predictions that similarly high rates of coverage could be achieved for the HPV vaccine. However, currently, only the recommendation for HBV vaccination is supported by mandates for school entry in most states. Uptake of the HPV vaccine has lagged far behind U.S. goals for public health promotion. The aim of this paper is to examine factors which may account for the divergent pathways of the two vaccines. Four main factors are identified: logistical challenges of vaccine administration, attitudes of parents and healthcare providers, safety concerns, and cost. For each factor examined, recommendations are offered to confront similar barriers likely to arise for future vaccines. The authors conclude that gender-neutral state mandates coupled with school-located vaccination programs, stronger gender-neutral messaging from pharmaceutical companies and healthcare providers, and younger age of vaccine administration, if approved, present the most promising approaches to improving uptake of the HPV vaccine, and similar vaccines down the road.

Abstract
This review reported notable advances in pediatrics that have been published in 2018. We have highlighted progresses in allergy, cardiology, critical care, endocrinology, hereditary metabolic diseases, gastroenterology, infectious diseases, neonatology, nutrition, respiratory tract disorders and surgery. Many studies have informed on epidemiologic observations. Promising outcomes in prevention, diagnosis and treatment have been reported. We think that advances realized in 2018 can now be utilized to ameliorate patient care.

Abstract
BackgroundVaccination policy in France was previously characterised by the coexistence of eight recommended and three mandatory vaccinations for children younger than 2 years old. These 11 vaccines are now mandatory for all children born after 1 January 2018.AimTo study the French population's opinion about this new policy and to assess factors associated with a positive opinion during this changing phase.MethodsA cross-sectional survey about vaccination was conducted from 16 November-19 December 2017 among the GrippeNet.fr cohort. Data were weighted for age, sex and education according to the French population. Univariate and multivariate analyses were performed to identify factors associated with a favourable opinion on mandatory vaccines' extension and defined in the '3Cs' model by the World Health Organization Strategic Advisory Group of Experts working group on vaccine hesitancy.ResultsOf the 3,222 participants (response rate 50.5%) and after adjustment, 64.5% agreed with the extension of mandatory vaccines. It was considered a necessary step by 68.7% of the study population, while 33.8% considered it unsafe for children and 56.9% saw it as authoritarian. Factors associated with a positive opinion about the extension of mandatory vaccines were components of the confidence, complacency and convenience dimensions of the '3Cs' model.ConclusionsIn our sample, two thirds of the French population was in favour of the extension of mandatory vaccines for children. Perception of vaccine safety and benefits were major predictors for positive and negative opinions about this new policy.

Abstract
Immunization rates in Canada are suboptimal. Strategies such as making immunization mandatory for child care or school entry and financial incentives are used in other countries. Additional strategies that could work in the Canadian context include requiring accurate immunization records at school entry, implementing immunization registries at the provincial/territorial level, educating parents and school-aged children about vaccine-preventable diseases and making it more convenient for parents to ensure their children are fully immunized.

Abstract
Live attenuated vaccines elicit stronger protective immunity than dead vaccines. Distinct PAMPs designated as vita-PAMPs signify microbial viability to innate immune cells. Two vita-PAMPs have been characterized: cyclic-di-adenosine-monophosphate (c-di-AMP) and prokaryotic messenger RNA (mRNA). c-di-AMP produced by live Gram-positive bacteria elicits augmented production of STING-dependent type-I interferon, whereas prokaryotic mRNA from live bacteria is detected by TLR8 enabling discrimination of live from dead bacteria. Bacterial mRNA from live Gram-negative bacteria triggers a heightened type-I interferon and NLRP3 inflammasome response. By mobilizing unique viability-associated innate responses, vita-PAMPs mobilize adaptive immunity that best elicits protection, including follicular T helper cell and antibody responses. Here, we review the molecular mechanisms that confer the unique adjuvanticity of vita-PAMPs and discuss their applications in vaccine design.

Abstract
Background The detection of wild poliovirus in Israeli sewage in May 2013 led the health authorities to decide that children who had been vaccinated with IPV would also be vaccinated with OPV. The decision sought to protect vulnerable Israeli individuals who were either not vaccinated with IPV or who suffered from an immune deficiency, to preserve Israel’s status as a polio-free country, to prevent the virus’ “exportation” into vulnerable polio-free countries, and to participate in the global efforts toward the eradication of polio. After a massive public persuasion campaign, 79% of the children born after 2004 were vaccinated as well as 69% of the children residing in central Israel. A 2014 State Comptroller Report stated that the Ministry of Health should draw conclusions from the low compliance rates in certain Israeli regions. Goals The article seeks to examine the legal legitimacy of mandatory vaccination in the service of eradicating a contagious disease (as opposed to preventing a pandemic outbreak), which was one of the objectives in the 2013 Polio case. It more specifically relates to current Israeli law as well as to a hypothetical new public health law which would authorize health officials to oblige vaccination and enforce this through the use of criminal sanctions. Method Qualitative content analysis through the interpretation of court judgements, laws, legislative protocols, health ministry guidelines and documented discussions of the Advisory Committee on Infectious Diseases and Immunization. Main findings and conclusion A mandatory vaccination backed by criminal sanctions in the service of the eradication of contagious diseases would probably be perceived as infringing on the constitutional right to autonomy to a greater extent than necessary according to Israeli law and case law precedents. There may be some added value inherent in a new public health law which would authorize health officials to oblige vaccination where nonrestrictive measures have been ineffective. However, the law should also specify a variety of sanctions to accompany the enforcement of mandatory vaccinations which would be formulated from least to most restrictive according to the “intervention ladder” concept. The law should also describe the circumstances which would justify the implementation of each and every sanction as well as the procedural safeguards designed for established decisions and fairness toward the individual(s) whose rights are infringed by the application of these sanctions.

Abstract
School-based compulsory vaccination laws have provoked debates over the legitimacy of government coercion versus the scope of parental rights. A key point of contention in these school vaccination laws are provisions known as exemption clauses that allow some parents to enroll their children in school unimmunized for reasons other than medical conditions. For more than three decades Mississippi and West Virginia stood apart as the only two US states that did not offer nonmedical exemptions to school vaccination laws. But other states seem to be moving in this direction, such as California, which in 2015 eliminated nonmedical exemptions following the Disneyland measles outbreak. The apparent shift creates an opportune moment to look at the experiences of Mississippi and West Virginia. Through a review of legislative histories, legal rulings, media accounts, and interviews with health officials in the two states, we consider the reasons for and consequences of their allowing only medical exemptions and the prospects their approach holds out for other states that may wish to emulate it. The experiences of these two states suggest that contrary to conventional wisdom, it may be politically tenable to limit exemptions to only medical reasons without damaging either the stature of public health or the immunization system.

Abstract
"Vaccine hesitancy" is a concept now frequently used in vaccination discourse. The increased popularity of this concept in both academic and public health circles is challenging previously held perspectives that individual vaccination attitudes and behaviours are a simple dichotomy of accept or reject. A consultation study was designed to assess the opinions of experts and health professionals concerning the definition, scope, and causes of vaccine hesitancy in Canada. We sent online surveys to two panels (1- vaccination experts and 2- front-line vaccine providers). Two questionnaires were completed by each panel, with data from the first questionnaire informing the development of questions for the second. Our participants defined vaccine hesitancy as an attitude (doubts, concerns) as well as a behaviour (refusing some / many vaccines, delaying vaccination). Our findings also indicate that both vaccine experts and front-line vaccine providers have the perception that vaccine rates have been declining and consider vaccine hesitancy an important issue to address in Canada. Diffusion of negative information online and lack of knowledge about vaccines were identified as the key causes of vaccine hesitancy by the participants. A common understanding of vaccine hesitancy among researchers, public health experts, policymakers and health care providers will better guide interventions that can more effectively address vaccine hesitancy within Canada.

Abstract
PURPOSE The efficacy of immunization mandates for childcare or school entry is a long-standing controversy. The United States (US) adopted school entry immunization mandates in the 1800s, while most countries still do not have mandates. The objective of this systematic review was to analyze the evidence that immunization uptake increases with mandates. METHODS A search was conducted for studies that compared immunization uptake in a population prior to and after mandates, or in similar populations with one group having and the other not having mandates. Data were extracted and synthesized qualitatively due to the heterogeneity of study design. RESULTS Eleven before-and-after studies and ten studies comparing uptake in similar populations with and without mandates were included. Studies were from the US (n = 18), France (n = 1) and Canada (n = 2). Eleven of the 21 studies looked at middle school mandates. All but two studies showed at least a trend towards increased uptake with mandates. Higher uptake was associated with a more long-standing mandate. CONCLUSIONS Immunization mandates have generally led to increased short-term and long-term uptake in the group to whom the mandate applies. Many studies have centered around middle school mandates in the US and there is a paucity of studies of childcare mandates or of studies of mandates in other countries or in settings with relatively high baseline immunization uptake.

Abstract
Vaccine hesitancy is an emerging term in the socio-medical literature which describes an approach to vaccine decision making. It recognizes that there is a continuum between full acceptance and outright refusal of some or all vaccines and challenges the previous understanding of individuals or groups, as being either anti-vaccine or pro-vaccine. The behaviours responsible for vaccine hesitancy can be related to confidence, convenience and complacency. The causes of vaccine hesitancy can be described by the epidemiological triad i.e. the complex interaction of environmental- (i.e. external), agent- (i.e. vaccine) and host (or parent)- specific factors. Vaccine hesitancy is a complex and dynamic issue; future vaccination programs need to reflect and address these context-specific factors in both their design and evaluation. Many experts are of the view that it is best to counter vaccine hesitancy at the population level. They believe that it can be done by introducing more transparency into policy decision-making before immunization programs, providing up-to-date information to the public and health providers about the rigorous procedures undertaken before introduction of new vaccines, and through diversified post-marketing surveillance of vaccine-related events.

Abstract
Despite being recognized as one of the most successful public health measures, vaccination is perceived as unsafe and unnecessary by a growing number of parents. Anti-vaccination movements have been implicated in lowered vaccine acceptance rates and in the increase in vaccine-preventable disease outbreaks and epidemics. In this review, we will look at determinants of parental decision-making about vaccination and provide an overview of the history of anti-vaccination movements and its clinical impact.

(1) Innovation to develop the evidence base for action; (2) a technical package of a limited number of high-priority, evidence-based interventions that together will have a major impact; (3) effective performance management, especially through rigorous, real-time monitoring, evaluation, and program improvement; (4) partnerships and coalitions with public- and private-sector organizations; (5) communication of accurate and timely information to the health care community, decision makers, and the public to effect behavior change and engage civil society; and (6) political commitment to obtain resources and support for effective action. Programs including smallpox eradication, tuberculosis control, tobacco control, polio eradication, and others have made progress by addressing these 6 areas.

Abstract
Despite being recognized as one of the most successful public health measures, vaccination is perceived as unsafe and unnecessary by a growing number of individuals. Lack of confidence in vaccines is now considered a threat to the success of vaccination programs. Vaccine hesitancy is believed to be responsible for decreasing vaccine coverage and an increasing risk of vaccine-preventable disease outbreaks and epidemics. This review provides an overview of the phenomenon of vaccine hesitancy. First, we will characterize vaccine hesitancy and suggest the possible causes of the apparent increase in vaccine hesitancy in the developed world. Then we will look at determinants of individual decision-making about vaccination.

Abstract
Vaccination provides many health and economic benefits to individuals and society, and public support for immunization programs is generally high. However, the benefits of vaccines are often not fully valued when public discussions on vaccine safety, quality or efficacy arise, and the spread of misinformation via the internet and other media has the potential to undermine immunization programs. Factors associated with improved public confidence in vaccines include evidence-based decision-making procedures and recommendations, controlled processes for licensing and monitoring vaccine safety and effectiveness and disease surveillance. Community engagement with appropriate communication approaches for each audience is a key factor in building trust in vaccines. Vaccine safety/quality issues should be handled rapidly and transparently by informing and involving those most affected and those concerned with public health in effective ways. Openness and transparency in the exchange of information between industry and other stakeholders is also important. To maximize the safety of vaccines, and thus sustain trust in vaccines, partnerships are needed between public health sector stakeholders. Vaccine confidence can be improved through collaborations that ensure high vaccine uptake rates and that inform the public and other stakeholders of the benefits of vaccines and how vaccine safety is constantly assessed, assured and communicated.

Abstract
Parental vaccine hesitancy is a growing problem affecting the health of children and the larger population. This article describes the evolution of the vaccine hesitancy movement and the individual, vaccine-specific and societal factors contributing to this phenomenon. In addition, potential strategies to mitigate the rising tide of parent vaccine reluctance and refusal are discussed.

Abstract
OBJECTIVE To characterize the attitudes of low-income and minority parents/guardians toward vaccinating sons against human papillomavirus (HPV). METHODS In 2010-2011, we conducted qualitative interviews with 68 black, 24 white, and 28 Latino parents/guardians of sons. We identified attitudes related to HPV vaccination, vaccine mandates for males and females, and adolescent male sexuality using constructs from the Health Belief Model and methods based in grounded theory. RESULTS Most participants were concerned that their sons could be exposed to HPV through sexual experimentation and believed that the consequences of HPV infection could be severe; thus, 75% would accept HPV vaccine for their sons. Yet the lack of efficacy and safety information specifically pertaining to males posed barriers. More black (73%) and Latino (86%) than white (44%) participants supported school-entry requirements for HPV vaccination. CONCLUSIONS Low-income and minority parents/guardians were generally receptive toward vaccinating their sons against HPV; racial/ethnic differences emerged regarding school-entry mandates.

Abstract
The results of Slovenian surveillance system of AEFI which was in place for the early detection and investigation of rare adverse events were analysed. The reports about AEFI obtained from physicians, and self-assessment questionnaires from vaccinated persons showed predominantly non-serious and expected side effects. Nine reports (3%) included serious AEFI. No deaths consequent to vaccination were reported. A total of 1170 AEFI were reported by physicians and 1030 by self-assessment. Overall, the most commonly reported AEFI either by physicians or persons were local site reactions (37.3% and 50.5%), tiredness (11.9% and 6.8%) and fever or malaise (10.8% and 6.3%). More than 100,000 people were vaccinated with pandemic vaccines in Slovenia. The type and the frequency of AEFI detected through Slovenian AEFI surveillance system are comparable to the results from other surveillance systems. The benefit-risk balance for the pandemic vaccines used in Slovenia remains positive.
