Abstract
This study investigated racial/ethnic differences in pregnant and postpartum women's intentions to receive the COVID-19 vaccination (maternal COVID-19 vaccination intent) and intentions to vaccinate their children against COVID-19 (child COVID-19 vaccination intent) during the early months of the COVID-19 pandemic (April-June 2020). This study also assessed Health Belief Model constructs to examine their influence on maternal and child COVID-19 vaccination intent by race/ethnicity. This study includes 489 US pregnant and postpartum women (18-49 years) recruited via Prolific Academic to complete a 55-item cross-sectional online survey. Crude and adjusted logistic regression analyses were conducted to determine the associations between race/ethnicity, maternal COVID-19 vaccination intent, and child COVID-19 vaccination intent. Among pregnant women, the odds of maternal COVID-19 vaccination intent (aOR = 2.20, 95% CI: .862, 5.61) and child COVID-19 vaccination intent (aOR = .194, 95% CI: .066, .565) among NH Black women were statistically significantly lower than that of NH White women after adjustment for demographic, health, and health belief model variables. Among postpartum women, although some racial differences in maternal or child COVID-19 vaccination intent were observed, these differences were not statistically significant in unadjusted and adjusted models. The findings have implications for future research and interventions which should adopt a racial health equity lens and identify strategies grounded in institutional trustworthiness and systems perspectives to address racial/ethnic disparities in COVID-19 vaccination intent among pregnant and postpartum women during novel pandemics.

[PMID: 36146600 PMCID: PMC9500877 DOI: 10.3390/vaccines10091524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 09/06/2022] [Accepted: 09/10/2022] [Indexed: 11/16/2022] Open
Abstract
Vaccines are one of the most important achievements of modern medicine in maintaining the health of the population. The prolonged pandemic and subsequent lockdowns meant that the new COVID-19 vaccine was regarded by scientists and society as the way to end the pandemic and return to normal life. The purpose of this study was to analyze the factors responsible for the feeling of fear due to COVID-19 infection and the attitudes of medical students towards vaccination against COVID-19. A cross-sectional study was conducted online among medical students using standardized questionnaires: the Fear of COVID-19 scale and the Vaccination Attitude Examination scale. According to the results obtained, the respondents had a low level of fear of COVID-19 and the majority had positive attitudes towards vaccination against COVID-19. Regression analysis showed that the main predictors of fear of the pandemic and attitudes towards vaccination were age, sex, field of study, and sources of knowledge about vaccines. The analysis of factors related to the discussed issues can be the basis to formulate educational and preventive programs, to shape positive attitudes of future health sector employees toward the issue of preventive vaccination, as well as for the development of strategies to promote vaccination against COVID-19.

Souther A, Chang MH, Tassier T. It's worth a shot: urban density, endogenous vaccination decisions, and dynamics of infectious disease. JOURNAL OF ECONOMIC INTERACTION AND COORDINATION 2022; 18:163-189.

Abstract
We develop an agent-based model of vaccine decisions across a heterogeneous network model with urban and rural regions. In the model, agents make rational decisions to vaccinate or not, based on the relative private costs of vaccinations and infections as well as an estimated probability of infection if not vaccinated. The model is a methodological advance in that it provides an economic rationale for traditional threshold models of vaccine decision-making that are commonly used in agent-based network models of vaccine choice. In the model, more dense urban regions have more connections between agents than less dense rural regions. Higher density leads to higher levels of vaccine usage and lower rates of infection in urban regions within the model. This finding adds to the more commonly discussed socio-economic reasons for higher levels of vaccination usage in urban areas compared to rural areas. In addition to this direct contribution, the paper emphasizes the importance of endogenous decision-making in models of epidemiology. For instance, we find that networks that lead to larger epidemics in exogenous vaccination models lead to smaller epidemics in our model because agents use vaccinations to offset the additional risk introduced by these network structures. Endogenous agent responses to risk need to be incorporated into theoretical and empirical models of economic epidemiology.

Vaccines (Basel) 2022; 10:933. [PMID: 35746539 PMCID: PMC9228411 DOI: 10.3390/vaccines10060933] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 05/24/2022] [Accepted: 06/03/2022] [Indexed: 02/01/2023] Open
Abstract
Even though vaccination is the most effective measure against COVID-19 infections, vaccine rollout efforts have been hampered by growing anti-vaccine attitudes. Based on current knowledge, we identified three domains (beliefs, discrimination, and news) as our correlates of primary interest to examine the association with anti-vaccine attitudes. This is one of the first studies to examine key correlates of anti-vaccine attitudes during the critical early stages of vaccine implementation in the United States. An online survey was administered in May 2021 to a non-representative, nationally based sample of adults (N = 789). Using multivariable logistic regression analysis, we found that individuals who expressed worry about COVID-19 (OR = 0.34, 95% CI 0.21, 0.55) and had greater knowledge of COVID-19 (OR = 0.50, 95% CI 0.25, 0.99) were less likely to hold anti-vaccine attitudes. Conversely, individuals who held stigmatizing views of COVID-19 (OR = 2.47, 95% CI 1.53, 3.99), had experienced racial discrimination (OR = 2.14, 95% CI 1.25, 3.67) and discrimination related to COVID-19 (OR = 2.84, 95% CI 1.54, 5.24), and who had been watching Fox News (OR = 3.95, 95% CI 2.61, 5.97) were more likely to hold anti-vaccine attitudes. These findings suggest COVID-19 beliefs, experiences of discrimination, and news sources should be considered when designing targeted approaches to address the anti-vaccine movement.

Caregivers' Sources of Information About Immunization as Predictors of Delayed Childhood Vaccinations in Saudi Arabia During the COVID-19 Pandemic: A Cross-Sectional Questionnaire Study. Risk Manag Healthc Policy 2021; 14:3541-3550. [PMID: 34466043 PMCID: PMC8403080 DOI: 10.2147/rmhp.s312148] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 08/13/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose This study compared the most used sources of information by caregivers for scheduled childhood vaccination in Saudi Arabia before and during the COVID-19 pandemic and examined the effect of this decision-making. Methods An electronic survey was administered to 577 caregivers of children aged ≤2 years residing in Saudi Arabia during the COVID-19 pandemic curfew. The sources of information on childhood vaccination considered by the caregivers and their influence on the caregivers’ decision to delay scheduled vaccination were assessed and statistically analyzed. Results Most participants (90.8%) were mothers aged 32.6 ± 5.7 years. Before the pandemic, most caregivers sought information about children’s vaccinations personally from the healthcare workers, or trustworthy sources, including the Ministry of Health (MOH), MOH call center 937, and MOH Sehha app. However, during the pandemic, there was a noticeable decrease in the searches for health information through professional consultations (in person and health websites) and a significant increase in the use of social media platforms. Twitter was the most used platform (29.9%) and the use of Snapchat was significantly higher during the lockdown period compared to its use before the pandemic (21.9% vs 17.2%, P < 0.001). The use of social media not only increased the level of fear among the caregivers but also had a negative effect on their decisions about children’s vaccinations. Searches on YouTube and Facebook particularly increased the odds of delaying vaccinations by 2.63 times (P = 0.008) and 3.66 times (P = 0.025), respectively. Conclusion During the pandemic, caregivers’ health-information seeking behavior was directed towards social media networking. In Saudi Arabia, YouTube and Facebook, in particular, played an important role in the caregivers’ decision-making about childhood vaccinations. The results of this survey provide valuable information on how to reach the Saudi population and launch an effective awareness campaign using the most commonly accessed and influential sources of information.

The Model of "Informed Refusal" for Vaccination: How to Fight against Anti-Vaccinationist Misinformation without Disregarding the Principle of Self-Determination. Vaccines (Basel) 2021; 9:vaccines9020110. [PMID: 33535717 PMCID: PMC7912813 DOI: 10.3390/vaccines9020110] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 01/26/2021] [Accepted: 01/27/2021] [Indexed: 12/15/2022] Open
Abstract
Vaccines are arguably a public health success story as well as an incredibly cost-effective medical resource. Despite this, worldwide concerns about their safety are growing, with the risk of increased morbidity and mortality in vaccine-preventable diseases because of vaccine refusal. The global political trend in developed countries is to increasingly reduce mandates and the compulsory nature of vaccination programs. This is due to strong opposition from anti-vaccination movements and groups. While these have existed since the beginnings of vaccinology, they have recently gained a strong foothold through massive exploitation of the media and especially the internet. This has led to widespread misinformation and greater difficulty for governments and health institutions in dealing with parents’ concerns and misconceptions. Common strategies in order to maintain a high degree of public acceptance of vaccines include the enhancement of adverse effect reporting systems, the enrichment of scientific literature, and the dissemination of targeted information to parents and health care providers. Vaccine risk perception, in fact, largely exceeds the evidence and is linked to well-known general population cognitive bias, which must be recognized and corrected. Although there is no doubt about the convenience of universal vaccination, a lively international debate is underway with regard to the legitimacy of mandatory vaccination programs. Most scientists agree that the individual’s right to self-determination should be preserved. The only way to simultaneously protect the right to health is to introduce an informed refusal model, which aims to guarantee the highest coverage rates for vaccination.

Development of an Instrument to Assess Parents' Excessive Web-Based Searches for Information Pertaining to Their Children's Health: The "Children's Health Internet Research, Parental Inventory" (CHIRPI). J Med Internet Res 2020; 22:e16148. [PMID: 32293571 PMCID: PMC7191340 DOI: 10.2196/16148] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 12/29/2019] [Accepted: 01/27/2020] [Indexed: 01/26/2023] Open
Abstract
Background People often search the internet to obtain health-related information not only for themselves but also for family members and, in particular, their children. However, for a minority of parents, such searches may become excessive and distressing. Little is known about excessive web-based searching by parents for information regarding their children’s health. Objective This study aimed to develop and validate an instrument designed to assess parents' web-based health information searching behavior, the Children’s Health Internet Research, Parental Inventory (CHIRPI). Methods A pilot survey was used to establish the instrument (21 items). CHIRPI was validated online in a second sample (372/384, 96.9% mothers; mean age 32.7 years, SD 5.8). Item analyses, an exploratory factor analysis (EFA), and correlations with parents’ perception of their children’s health-related vulnerability (Child Vulnerability Scale, CVS), parental health anxiety (modified short Health Anxiety Inventory, mSHAI), and parental cyberchondria (Cyberchondria Severity Scale, CSS-15) were calculated. A subset of participants (n=73) provided retest data after 4 weeks. CHIRPI scores (total scores and subscale scores) of parents with a chronically ill child and parents who perceived their child to be vulnerable (CVS+; CVS>10) were compared with 2×2 analyses of variances (ANOVAs) with the factors Child’s Health Status (chronically ill vs healthy) and perceived vulnerability (CVS+ vs CVS−). Results CHIRPI’s internal consistency was standardized alpha=.89. The EFA identified three subscales: Symptom Focus (standardized alpha=.87), Implementing Advice (standardized alpha=.74) and Distress (standardized alpha=.89). The retest reliability of CHIRPI was measured as rtt=0.78. CHIRPI correlated strongly with CSS-15 (r=0.66) and mSHAI (r=0.39). The ANOVAs comparing the CHIRPI total score and the subscale scores for parents having a chronically ill child and parents perceiving their child as vulnerable revealed the main effects for perceiving one’s child as vulnerable but not for having a chronically ill child. No interactions were found. This pattern was observed for the CHIRPI total score (η2=0.053) and each subscale (Symptom Focus η2=0.012; Distress η2=0.113; and Implementing Advice η2=0.018). Conclusions The psychometric properties of CHIRPI are excellent. Correlations with mSHAI and CSS-15 indicate its validity. CHIRPI appears to be differentially sensitive to excessive searches owing to parents perceiving their child’s health to be vulnerable rather than to higher informational needs of parents with chronically ill children. Therefore, it may help to identify parents who search excessively for web-based health information. CHIRPI (and, in particular, the Distress subscale) seems to capture a pattern of factors related to anxious health-related cognitions, emotions, and behaviors of parents, which is also applied to their children.

Reconsidering the Moralization of Health: Practices Versus Concepts, and What We Can Learn from Evidence-based Research. Camb Q Healthc Ethics 2020; 28:215-224.

Abstract
This article aims to do two things. First, it argues that moralization of health occurs not only at the practical level of individual healthcare choices and health states, but also at the conceptual level of health itself. This is most evident in cases where the concept of health is presumed to possess the property of "overridingness" when compared to competing values and norms, that is, when it is treated as taking precedence over other values and norms it may come into conflict with. Second, the article makes a case for being critically skeptical of specific deployments of the concept of health when it has been moralized in this way. In such cases, what typically results is that some other personal value/norm, or set of values/norms, held by the individual is treated as intrinsically at odds with the concept of health, which is presumed, uncritically, to be superior, often because it is taken to be free-standing and self-justifying. Yet, a growing body of evidence-based research suggests that the role played by dimensions of personal meaningfulness in the quality of individuals' overall health is quite underappreciated. It is useful to think of these dimensions of personal meaning and significance as representing the individual's values. Thus, taking these data more seriously ought to lead to a reevaluation of the moralization of health at the conceptual level. In the first place, it is not obvious that if the concept of health runs afoul of other values/norms held by an individual, the latter should automatically yield. In the second place, they suggest that other values/norms held by an individual are not necessarily intrinsically opposed to the concept of health, but in fact may go a good distance in support of it.

Abstract
Informed consent matters - so does protecting people from infectious diseases. This paper examines what the appropriate informed consent process for vaccines should look like and how the process is conceptualized by law and health authorities. Drawing on the extensive theoretical and empirical literature on informed consent and vaccination, this article sets out what an ideal informed consent process for vaccination would consist of, highlighting the need for autonomous decisions. To be autonomous, decisions need to be based on full, accessible information and reached without coercion. We suggest that the information provided must address the nature of the procedure - including benefits to the child, benefits to society, and risks. Parents should have their concerns and misconceptions addressed. The information needs to be accessible and include an opportunity to ask questions. Based on this ideal model we examined in detail the legal framework surrounding informed consent to vaccination and the process as conceptualized by health authorities in two countries, Israel and the United States, to assess whether they meet the requirements. These two countries are similar in some of their values, for example, the importance of individual autonomy, and face similar problems related to vaccine hesitancy. At the same time, there are meaningful differences in their vaccine policies and the current structures of their informed consent processes, allowing for a meaningful comparison. We found neither country met our ideal informed consent process, and suggested improvements both to the materials and to the processes used to obtain informed consent.

Abstract
For the past 10 years, influenza vaccination coverage rate in Poland remains at a low 3% threshold. This low rate may be related to the unsatisfactory knowledge of vaccination, influenza, and misperception of health risks in the general population. To examine these issues, we used an online questionnaire consisting of 12 closed questions. The basic knowledge on influenza and vaccination was examined. The questionnaire was completed by 1669 persons, mostly young women. Generally, 73% of respondents passed the threshold of 70% correct answers, but important gaps in their knowledge were identified concerning the persons at risk of developing the infection (7.9% of correct answers) and the timing of vaccination (8.4% of correct answers). Although most respondents did identify the etiologic agent correctly (91.1% knew influenza is caused by a virus), only 12.3% knew that the vaccines registered in Poland contain fragments of viruses or its antigens, while 63.1% thought the vaccines contain live bacteria. In conclusion, the knowledge on influenza vaccination is deficient in the general population. Education on immunization should be prioritized to increase vaccination coverage rate in Poland.

Abstract
Measles is a highly infectious viral disease that continues to be a challenge for many countries worldwide. Although significant improvements have been observed since the introduction of vaccines, measles remains endemic in Romania. Contributing factors include vaccine hesitancy, difficulties in delivering doses to the population, and even the lack of sufficient vaccine supplies. These problems are further exacerbated by an inadequate implementation of public health measures, ranging from inefficient communication programs to the absence of a legislative framework concerning immunization. Moreover, many of the recent outbreaks were associated with chains of transmission in other countries, thus making the control of measles in Romania relevant at an international level. As many difficulties exist, understanding the key factors that limit the success of public health programs may provide guidance in shaping future strategies. Because similar issues are being faced in various other countries, the management of measles in Romania offers valuable lessons for researchers and policy-makers alike.

Abstract
Vaccination has become an integral part of public health, since an increase in overall vaccination in a given population contributes to a decline in infectious diseases and mortality. Vaccination also contributes to a lower rate of infection even for nonvaccinators due to herd immunity ((Brisson and Edmunds, 2002)). In this work we model human decision-making (with respect to a vaccination program in a single-payer health care provider country) using a leader-follower game framework. We then extend our model to a discrete dynamic game, where time passing is modelled by risk perception changes among population groups considering whether or not to vaccinate. The risk perception changes are encapsulated by probability transition matrices. We assume that the single-payer provider has a given fixed budget which would not be sufficient to cover 100% of a new vaccine for the entire population. To increase the potential coverage, we propose the introduction of a partial vaccine adoption policy, whereby an individual would pay a portion of the vaccine price and the single payer would support the rest for the entire population. We show how this policy, together with changes in risk perceptions regarding vaccination, impact the strategic decisions of individuals in each group, the policy cost under budgetary constraints and, ultimately, how it impacts the overall uptake of the vaccine in the entire population.

Abstract
A growing tendency to refuse child vaccination is commonly regarded as a reason for concern. Attempts to promote vaccination by authorities often prove to be unsuccessful or even counter-productive. The aim of this study was to explore how parents perceived four messages used to promote vaccination. In eight focus groups ( N = 73), we presented participants with messages and asked them to assess them. Using thematic analysis, we identified themes that our participants considered the most important. Messages that promote vaccination should be unambiguous, more balanced, not focus on repeating the negative effects of vaccine-preventable diseases and provide links to the evidence.

Abstract
School nurses work in a unique environment with key opportunities to address parental concerns and questions regarding their child's health. A common concern for parents during school enrollment is childhood vaccination safety and efficacy. As public health leaders, school nurses are well respected among parents, therefore school nurses are in a prime position to educate parents and promote childhood vaccinations while also dispelling common vaccination myths. The purpose of this integrative literature review is to synthesize evidence-based answers to common parental questions regarding childhood vaccinations.

Abstract
Thousands of U.S. parents choose to refuse or delay the administration of selected vaccines to their children each year, and some choose not to vaccinate their children at all. While most physicians continue to provide care to these families over time, using each visit as an opportunity to educate and encourage vaccination, an increasing number of physicians are choosing to dismiss these families from their practice unless they agree to vaccinate their children. This paper will examine this emerging trend along with the reasons given by those who advocate such an approach. I will argue that the strategy of refusing to allow families into a clinic unless they agree to vaccinate their children is misguided, and the arguments for doing so fail to stand up to close scrutiny. Such a strategy does not benefit the child or the health of the community, and may have a negative impact on both. Furthermore, some of the arguments in support of dismissal policies ignore the importance of professional obligation and appear to favor self-interest over the interest of the patient.

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.

Abstract
Mathematical models that couple disease dynamics and vaccinating behaviour often assume that the incentive to vaccinate disappears if disease prevalence is zero. Hence, they predict that vaccine refusal should be the rule, and elimination should be difficult or impossible. In reality, countries with non-mandatory vaccination policies have usually been able to maintain elimination or very low incidence of paediatric infectious diseases for long periods of time. Here, we show that including injunctive social norms can reconcile such behaviour-incidence models to observations. Adding social norms to a coupled behaviour-incidence model enables the model to better explain pertussis vaccine uptake and disease dynamics in the UK from 1967 to 2010, in both the vaccine-scare years and the years of high vaccine coverage. The model also illustrates how a vaccine scare can perpetuate suboptimal vaccine coverage long after perceived risk has returned to baseline, pre-vaccine-scare levels. However, at other model parameter values, social norms can perpetuate depressed vaccine coverage during a vaccine scare well beyond the time when the population's baseline vaccine risk perception returns to pre-scare levels. Social norms can strongly suppress vaccine uptake despite frequent outbreaks, as observed in some small communities. Significant portions of the parameter space also exhibit bistability, meaning long-term outcomes depend on the initial conditions. Depending on the context, social norms can either support or hinder immunization goals.
