Rural-Urban Disparities in Vaccine Hesitancy among Adults in South Tyrol, Italy

Anti-HBs Seroprevalence in Blood Donors from Tyrol, Austria

Background/Objectives: Antibodies against the hepatitis B surface antigen (anti-HBs) are a marker of immunity against hepatitis B virus (HBV) infections. There is uncertainty about the anti-HBs seroprevalence in the general population of Austria. Methods: We conducted a cross-sectional analysis in blood donors from the Federal State of Tyrol in Austria (August-September 2023) to estimate anti-HBs seroprevalence and median antibody levels. Results: We enrolled 3935 blood donors (median age 47.6 years [25th-75th percentile: 33.3-56.6]; 40.7% female), who were hepatitis B surface antigen negative and had no detectable HBV-DNA. Overall seroprevalence was 51.4% (95% CI: 49.8-52.9%). Anti-HBs seropositivity decreased with higher age (p < 0.001), with 70.3% (66.1-74.3%) being seropositive among participants < 25 years of age and 30.2% (24.2-36.9%) in those aged ≥ 65 years. More females than males were seropositive (54.3% [51.8-56.7%] vs. 49.4% [47.4-51.4%]; p = 0.003). Seroprevalence was significantly higher in urban than in rural areas in participants aged 40 to <55 (p = 0.045) and ≥55 years (p = 0.001). Among 2022 seropositive participants, the overall median anti-HBs antibody level was 539.3 IU/L (25th-75th percentile: 116.3-5417.0). Furthermore, 5% of the participants had an anti-HBs antibody level between 10 and <20 IU/L, 18% between 20 and <100 IU/L, and 77% ≥100 IU/L. Conclusions: Anti-HBs seroprevalence in blood donors from Tyrol, Austria, was 51.4% between August and September 2023 and differed across age, sex, and residence area. Catch-up vaccination programs, especially targeting the elderly living in rural areas, are needed to close HBV immunity gaps.

Exploring Parental Attitudes and Perceptions Regarding Childhood Vaccinations in Greece: A Study Within the Framework of the National Health Examination Survey (EMENO)

AIM

Vaccinations have reduced illnesses and mortality rates globally, yet negative attitudes and uncertainty about them hinder their acceptability and efficacy. The study aims to document Greek parents' immunization perceptions and risk factors.

METHODS

Spanning 2014-2017, 447 parents (68% mothers) who participated in the Greek Health Examination Survey EMENO (National Survey of Morbidity and Risk Factors) completed an interview-delivered questionnaire. Attitudes were categorized into three groups: absolutely positive, positive, and negative. Absolutely positive attitudes included positive responses to all five statements in favor of vaccination and negative responses to the two statements against vaccination. Negative attitudes included positive responses to either one or both statements against vaccination and negative responses to all five statements in favor of vaccination.. All other participants were categorized as having a positive attitude. Skepticism towards vaccinations was classified into skeptical and non-skeptical groups based on responses to five statements implying uncertainty or skepticism. Participants were considered skeptical if they provided positive responses to at least three of these statements, and non-skeptical if they had none or up to two positive responses. The statistical analysis accounted for the study design whereas inverse probability weighting was used to adjust for non-response and multiple imputations were employed to impute missing values. The components of parental attitude and vaccine skepticism were identified using weighted multinomial logistic regression and logistic regression, respectively.

RESULTS

In total, 16.6% were classified as having absolutely positive attitudes towards vaccinations whereas 42.1% were skeptical of vaccines. Of all participants, 96.0% agreed that vaccinations are essential for their child's well-being and adhere to scientific recommendations. However, concerns were also mentioned, with 26.2% worrying about potential adverse effects, and 21.6% believing it is better to acquire immunity through illness rather than vaccination. Positive participants, compared to absolutely positive ones, were more likely to be of Greek origin (adjusted relative rate ratio (aRRR): 3.35; 95% CI: 1.53-7.30) and living in semi-urban areas (aRRR: 4.84; 95% CI: 1.77-13.29). Negative participants, in contrast, were more likely to have higher education (aRRR: 2.98; 95% CI: 1.05-8.44) but also to live in semi-urban areas (aRRR: 6.43; 95% CI: 1.69-24.56). Furthermore, parents of Greek origin had significantly higher odds of being skeptical towards vaccination (adjusted Odds Ratio (aOR): 2.86; 95% CI: 1.36-5.98), while married or cohabiting parents had lower odds of being skeptical compared to single parents (aOR: 0.60; 95% CI: 0.35-1.06).

CONCLUSIONS

While parents in this study recognize the importance of childhood immunizations, there is a widespread presence of negative attitudes and skepticism that can have a detrimental impact on vaccination rates.

Evolving Altruistic Attitudes towards Vaccination Post COVID-19 Pandemic: A Comparative Analysis across Age Groups

Altruism plays an essential role in promoting vaccine uptake, an issue that came to the fore during the COVID-19 pandemic through discussions of herd immunity and altruistic motivations. In response, the primary objective of this cross-sectional survey was to explore how altruistic attitudes have evolved in the post-pandemic era and to assess their effectiveness in motivating vaccination behavior in different age groups. The study aimed to elucidate changes in altruistic motivations for vaccination and their implications for public health strategies. Using a representative sample of the adult population of South Tyrol, Italy, including 1388 participants, altruism was assessed in 2023 with the scales of the Elderly Care Research Center (ECRC) and the International Personality Item Pool (IPIP) subscale of the version 5F30F-R1. Its association with demographic variables, vaccination attitudes and personal beliefs in two age groups (18-69 years, 70+ years) was analyzed. The results reveal distinct predictors of altruism across these scales and age groups, suggesting a shift in altruistic attitudes towards vaccination when comparing data from a similar survey conducted in 2021 with the 2023 results. Consequently, the use of altruism scales for different age groups is warranted. This study highlights the need for further research in this field. It concludes that while promoting altruistic behavior to increase vaccine uptake appears to be effective primarily among the younger population, emphasizing personal safety is more appropriate for encouraging vaccination among older individuals.

Vaccine Hesitancy and Public Mistrust during Pandemic Decline: Findings from 2021 and 2023 Cross-Sectional Surveys in Northern Italy

This study examines vaccine agreements in South Tyrol, Italy, within distinct socio-cultural and linguistic contexts. Using data from the 2021 and 2023 "COVID-19 Snapshot Monitoring" extended surveys, we assessed changes in attitudes towards COVID-19 and other vaccinations during the second and final years of the pandemic. Multivariate logistic regression analysis was used to examine factors such as trust in institutions, language groups, and the use of complementary and alternative medicine. The representativeness of the study is supported by good participation rates, ensuring a comprehensive view of attitudes towards vaccination in the region. The results show a shift in public agreement with the national vaccination plan to 64% by 2023, from a rate of about 73% agreement in 2021 (p < 0.001). A significant decrease in trust in health authorities and a negative correlation with complementary and alternative medicine consultations were observed. The results highlight the complex nature of vaccine hesitancy in diverse regions such as South Tyrol and underline the need for targeted communication strategies and trust-building initiatives to effectively reduce hesitancy. This study provides critical insights for the formulation of public health strategies in diverse sociocultural settings.

Parental intention to vaccinate children against seasonal influenza in the Eastern Mediterranean region: A cross-sectional study using the health belief model

Seasonal influenza vaccine is the most effective strategy for reducing influenza incidence and severity. Parental decision-making regarding childhood vaccination is influenced by one's vaccine-related beliefs. A cross-sectional study was conducted to determine the role of the Health Belief Model (HBM) in predicting parental intention to vaccinate their children against influenza in the Eastern Mediterranean Region (EMR). An anonymous online survey was distributed to parents of children aged 6 months to 18 years in 14 EMR countries. Out of the 5964 participants, 28.2% intended to vaccinate their children against influenza. Urban residents (OR = 0.55, 95%CI: 0.35-0.85), decision-making regarding child's health by the father alone (OR = 0.43, 95%CI: 0.34-0.55) or the mother alone (OR = 0.78, 95%CI: 0.65-0.93), having a child with a chronic illness (OR = 0.45, 95%CI: 0.38-0.53), reporting high perceived severity, susceptibility, and benefits (OR = 0.35, 95%CI: 0.30-0.40), and cues to action (OR = 0.45, 95%CI: 0.39-0.51) were inversely associated with parental unwillingness to vaccinate their children against influenza. While parents with a higher number of children in the household (OR = 1.08, 95%CI:1.03-1.12) and higher perceived barriers (OR = 2.92, 95%CI: 2.56-3.34) showed an increased likelihood of unwillingness to vaccinate their children. Interventions targeting parental beliefs and perceptions are necessary to improve influenza vaccination acceptance and coverage among children.

Socioeconomic Inequalities in COVID-19 Vaccine Hesitancy and Uptake in Greece and Cyprus during the Pandemic

Despite the rigorous investigation of the phenomenon of vaccine hesitancy and refusal during the COVID-19 pandemic, the socioeconomic determinants of this phenomenon remain poorly investigated on a global scale. Following proportional quota sampling, we conducted a population-based cross-sectional study. We recruited participants on-site and online from different settings, regions, and socioeconomic strata in two Eastern Mediterranean populations, Greece and Cyprus. Our approach provided a nationwide sample (n = 576) approaching the adult population structure of the two countries, with a slight underrepresentation of men and older people. Our results indicate clear socioeconomic differences in vaccine hesitancy and vaccination coverage, consistent with wider social inequalities in health. In particular, we reveal a clear socioeconomic gradient characterized by lower vaccine hesitancy and higher vaccination coverage, with increasing educational attainment and income. Additionally, participants residing in semi-urban areas show higher vaccine hesitancy and have lower vaccination coverage than those residing in urban and rural areas. Our results could inform Public Health approaches aiming to tackle the alarming phenomenon of vaccine hesitancy by enabling the targeting of population groups who are particularly vaccine-hesitant, rendering such approaches more targeted and effective while at the same time reducing inequalities in the control and prevention of infectious diseases.

Unravelling Vaccine Scepticism in South Tyrol, Italy: A Qualitative Analysis of Personal, Relational, and Structural Factors Influencing Vaccination Decisions

Low vaccine uptake in South Tyrol, particularly for non-coronavirus and SARS-CoV-2 vaccines, poses a significant public health challenge in the northernmost province of Italy. This qualitative study conducted in-depth interviews with a purposive sample of vaccine-sceptical parents to examine the factors that contribute to their vaccination decisions. The ten participants' children had varied vaccination statuses, ranging from unvaccinated to partially vaccinated or vaccinated as late as possible. Only one adult participant received the SARS-CoV-2 vaccine. Using Grounded Theory analysis, the emergent meta-category of 'self-relatedness' was identified, highlighting the importance of individual experiences and the social context. The study found that participants' social circles consisted of individuals with similar vaccination attitudes, often characterized by a shared affinity for nature. Although they accepted individuals with different views, they remained uninfluenced. Participants perceived healthcare professionals as one-sided and uncritical, expressing distrust toward state orders. They believed that parents should be responsible for their children's well-being rather than the state. Distrust in the state and healthcare system, exacerbated by the SARS-CoV-2 pandemic, was rooted in negative experiences. In contrast, the participants had positive experiences with natural healing, homeopathy, and trusting the natural course of events. They perceived themselves as tolerant, non-radical, curious, health-conscious, yet critical and questioning. Participants resisted coercion, fear-mongering, and state sanctions and sought alternatives to mandatory vaccination. To address the complex social and behavioural factors underlying vaccination refusal, this study suggests that vaccination advocates, policymakers, and information providers should engage in appreciative, personal, and well-founded information exchanges with vaccine-hesitant individuals. Broad and comprehensible information dissemination, flexibility, and freedom of decision are essential for increasing informed decision making. Further research is required to better understand the epistemic basis of vaccine hesitancy.

Epidemiology of the Acceptance of Anti COVID-19 Vaccine in Urban and Rural Settings in Cameroon

The COVID-19 pandemic rapidly evolved in December 2019 and to prevent its spread, effective vaccines were produced and made available to the population. Despite their availability so far in Cameroon, the vaccination coverage remains low. This study aimed at describing the epidemiology of the acceptance of vaccines against COVID-19 in some urban and rural areas of Cameroon. A cross-sectional, descriptive and analytical survey was conducted from March 2021 to August 2021 targeting unvaccinated individuals from urban and rural area. After receiving appropriate administrative authorizations and an ethical clearance from the Institutional Review Board (or Ethics Committee) of Douala University (N° 3070CEI-Udo/05/2022/M), a cluster sampling at many degrees was performed and a language-adapted questionnaire was completed by each consenting participant. Data were analyzed using Epi info version 7.2.2.6 software and for p-values < 0.05, the difference was considered as statistically significant. Out of 1053 individuals, 58.02% (611/1053) participants were residing in urban and 41.98% (442/1053) in rural areas. Good knowledge relative to COVID-19 was significantly higher in urban areas as compared to rural areas (97.55% vs. 85.07, p < 0.000). The proportion of respondents who intended to accept the anti COVID-19 vaccine was significantly higher in urban areas than rural areas (42.55% vs. 33.26, p = 0.0047). Conversely, the proportion of anti COVID-19 reluctant respondents thinking that the vaccine can induce a disease was significantly higher in rural areas than urban areas (54 (35.07 vs. 8.84, p < 0.0001). The significant determinants of anti-COVID-19 acceptance were the level of education (p = 0.0001) and profession in the rural areas (p ≤ 0.0001), and only the profession (p = 0.0046) in the urban areas. This study globally showed that anti-COVID-19 vaccination remains a major challenge in urban as well as rural areas in Cameroon. We should continue sensitizing and educating the population about vaccine importance in preventing the COVID-19 spread.

Age-Related Associations of Altruism with Attitudes towards COVID-19 and Vaccination: A Representative Survey in the North of Italy

BACKGROUND

During the coronavirus pandemic, altruism has been linked to personal protective behavior, vaccine development, and vaccination intention. Studies of the moderating effects of age on altruism in pandemic preparedness have not yet been conducted.

METHODS

A representative cross-sectional survey of residents of South Tyrol, Italy, was conducted in March 2021. Among the participants, 1169 were aged 18-69 years, and 257 were aged ≥ 70 years. The questionnaire collected information on sociodemographic and individual characteristics, including comorbidities, COVID-19-related experiences, trust in information, the likelihood of accepting the national vaccination plan, and altruism. A linear regression analysis was performed.

RESULTS

Among 1426 participants, the median altruism sum score was 24 (interquartile range, 20-26). In the participant group aged ≥ 70 years, the median altruism score was significantly higher than that in the younger group. Participants living in a single household were significantly less altruistic than other participants, while participants working in the health sector, living in a household at risk from coronavirus disease 2019, or suffering from a chronic disease were found to be more altruistic. Altruism showed significant positive correlations with age and agreement with the national vaccination plan and was negatively correlated with well-being. Trust in institutions was positively correlated with altruism only in the younger age group but not in the elderly. Linear regression models confirmed female gender and identified trust in institutions as a positive predictor of altruism. In the younger age group, increased well-being and restricted individual sports activities were associated with reduced altruism, whereas support of compulsory self-isolation after contact with a SARS-CoV-2-positive person and handwashing as a personal protective measure were positively associated.

CONCLUSION

Altruism is associated with various predictors of pandemic behavior and traits. The strengths of the identified positive and negative correlations support the modifying role of age in the effects of altruism on pandemic attitudes. Interventions that are likely to enhance altruism to improve pandemic preparedness in certain age groups require further study.
