Health Information Sources, Perceived Vaccination Benefits, and Maintenance of Childhood Vaccination Schedules

The multi-dimensional impact of different sources of information on influenza vaccination of college students in China

Objective: To explore whether/how the willingness of Chinese college students to receive the influenza vaccines in the sample is affected by different information channels. Participants: Two hundred and four volunteers were recruited to participate in an anonymous online survey. All participants were college students, mainly undergraduates (81.86%), with a higher proportion of women (56.86%). Methods: Participants answered anonymous questionnaires through the website, including demographic data (age, gender, education, etc.), media exposure channels and frequency, views and attitudes toward influenza vaccines, etc. An ordered logistic regression analysis was conducted to explore the effects of different information sources on influenza vaccination among college students. Results: Exposure to traditional media, digital media, and interpersonal communication promotes college students' understanding of influenza vaccines. Exposure to digital media alleviates college students' hesitation to vaccinate, while interpersonal interaction and digital media exposure promote college students' willingness to vaccinate. Conclusions: Digital media is increasingly important in the lives of Chinese college students to promote healthy behaviors such as influenza vaccinations.

Knowledge and trust of mothers regarding childhood vaccination in Rwanda

INTRODUCTION

Knowledge and trust are some of the contributing factors to vaccine acceptance(VA) and Vaccine hesitancy (VH) is one of the top threats to global health. A significant drop in childhood vaccination has been observed in recent years. One important reason that influences mothers' choice to either postpone or avoid children's vaccinations is knowledge and trust in childhood vaccines. This study aimed to assess mothers' knowledge and trust on vaccination of their children, and to examine the association between vaccination knowledge and selected socio-demographic factors.

METHODS

A cross-sectional survey was conducted from January 2022 to March 2022 to assess the knowledge and trust of mothers regarding childhood vaccination. Data was collected with self-administered questionnaires. Multivariable logistic regression analysis was employed to assess factors associated with childhood vaccine knowledge and trust.

RESULTS

Of the 2,126 Rwandan parents who participated in the study, the proportions with good knowledge of - and good trust in childhood vaccination were 95.5% and 91.4%, respectively. The popular sources of information about childhood vaccination were health care professionals (91.8%) and mass media (28.9%). Multinomial logistic regression analysis showed that good knowledge of - and trust in childhood vaccination were associated with the relationship with child(ren), education, occupation, and monthly income. The Multinomial logistic regression also revealed that the determinants of good knowledge of - and trust in childhood vaccination were; caregiver (p = 4.0 × 10-4, adjusted Odds Ratio (aOR); 1.7, 95%C.I; 1.3 - 2.3), no formal educational status (p = 3.3 × 10-2, aOR; 1.7, 95%C.I; 1.0 - 3.0), the unemployed occupational status (p = 2.4 × 10-2, aOR; 1.2, 95%C.I; 1.0 - 1.4), and persons on more than $401 per month (p = 2.0 × 10-4, aOR; 3.5, 95%C.I; 1.8 - 6.8).

CONCLUSION

The majority of parents in Rwanda had both good knowledge of-and good trust regarding childhood vaccination. Public health strategies to promote vaccination, education programmes as well as improved communication tools between health care professionals/traditional leaders/religious leaders and parents need to be considered to achieve favourable vaccination attitudes and practices for all parents in Rwanda.

Temporal Distance, Message Framing, and Consideration of Future Consequences: Parents' Willingness to Vaccinate Children Aged 5-11 Against COVID-19

Based on the construal level theory (CLT), this experiment employed a 2 (message framing: gain vs. loss) × 2 (temporal framing: proximal vs. distal) × 2 (consideration of future consequences: low vs. high) between-subjects factorial design. Parents (N = 409) of 5- to 11-year-old children in the United States from a pool of candidates pre-screened by Qualtrics participated in this study. Results indicated that parents with high CFC-Future were more receptive to messages advocating getting their children vaccinated against COVID-19. Parents with high CFC-Future reported higher risk perception in response to the proximal messages compared to the distal messages. For parents focusing on more distant outcomes, proximal messages generated more positive attitude and greater intention compared to distal messages in the loss-framed condition. The difference was not significant in the gain-framed condition. Theoretical and practical implications were discussed. Limitations and directions for future research were outlined.

"A Victim of Our Own Success:" Testing Jenny's First Sleepover's Dark Satire to Improve Attitudes Toward Childhood Vaccination

The COVID-19 pandemic resulted in substantially lower uptake of childhood vaccinations in the U.S. As vaccination rates struggle to rebound, childhood vaccine hesitancy continues to grow. Addressing vaccine disinformation and increasing catch-up vaccination is an urgent public health priority. The purpose of this study was to evaluate the effectiveness of "Jenny's First Sleepover," a darkly humorous satirical book about childhood vaccinations, to influence attitudes of vaccine hesitant parents. This study implemented a randomized pretest - posttest experimental design using a web-based survey with one intervention and one control. "Jenny's First Sleepover" improved attitudes toward vaccination among vaccine hesitant parents. Negative emotions were an important mediator of attitudes toward vaccinations. Findings identify mechanisms that increase effectiveness of satirical approaches, including the presentation of novel information about serious vaccine-preventable diseases with a dark narrative twist. Health communicators may consider a darkly humorous satirical approach to improve attitudes toward childhood vaccination among vaccine hesitant parents.

The Effects of the Culturally Tailored Narratives on COVID-19 Vaccine Confidence Among Hispanics: A Randomized Online Experiment

Guided by the health belief model (HBM), cultural sensitivity approach, and the theory of situated cognition, this study compares the effects of culturally tailored narratives and generic narratives on the COVID-19 vaccine confidence among Hispanics. It also examines an array of cognitive responses (perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and perceived side effects) associated with the COVID-19 vaccine confidence, and the interaction of these cognitive responses with the two narrative types of messaging. The findings suggest that Hispanics exposed to culturally tailored narratives are more confident in the COVID-19 vaccine compared to Hispanics exposed to generic narratives. The study provides support for the HBM, as the perceived benefit was positively related to vaccine confidence, and the perceived barrier was negatively associated with vaccine confidence. Finally, vaccine confidence was the strongest among Hispanics who had high perceived susceptibility and were exposed to culturally tailored narratives.

Understanding self-protective behaviors during COVID-19 Pandemic: Integrating the theory of planned behavior and O-S-O-R model

Adopting health preventive actions is one of the most effective ways to combat the COVID-19 pandemic. Based on the theory of planned behavior and the orientation-stimulus-orientation-response model, this study investigated the mechanisms by which health information exposure influenced individuals to adopt self-protective behaviors in the context of infectious disease. In this research, a convenience sampling was used and 2265 valid samples (Male = 843, 68.9% of participants aged range from 18 to 24) were collected in China. Structural equation modeling analysis was performed, and the analysis showed that health consciousness positively influenced the subsequent variables through interpersonal discussions and social media exposure to COVID-19-related information. The interaction between interpersonal discussion and social media exposure was found to be positively associated with the elements of the theory of planned behavior and risk perception. The findings also revealed that self-protective behavior was positively predicted by the components of the theory of planned behavior and risk perceptions, with subjective norms serving as the main predictor, followed by attitudes and self-efficacy.

Trust in Doctors, Positive Attitudes, and Vaccination Behavior: The Role of Doctor-Patient Communication in H1N1 Vaccination

Although there is a wide variety of scientific evidence that demonstrates the benefits of vaccination on a multitude of diseases, vaccination rates remain low while misperceptions about vaccines are on the rise. The primary objective of the present study is to examine the role of doctor-patient communication and vaccination. We test the impact of doctor-patient communication on trust in doctors' vaccine recommendations as a mediator, to understand the mechanisms leading to positive vaccination attitudes, and ultimately leading to actual H1N1 vaccination behavior. We use data from a nationally representative U.S. sample from one of the Multimedia Audience Research Systems (MARS) data sets collected by Kantar Media. Our results demonstrate the crucial role of doctor-patient communication in building patients' trust in doctors, which in turn positively impact vaccination attitudes and H1N1 vaccination behavior. Unlike other preventive health measures, getting vaccines after a pandemic is a critical decision because these vaccines are previously unknown. Our finding implies that verified communication from the physician's office may be one of the effective strategies during or after a pandemic. Our findings have implications for public health organizations to incorporate effective vaccination communication and could have critical implications for the COVID-19 vaccination.

Understanding CDC's Vaccine Communication during the COVID-19 Pandemic and Its Effectiveness in Promoting Positive Attitudes toward the COVID-19 Vaccine

The COVID-19 pandemic has imposed many communication challenges for public health authorities, especially communicating the safety, effectiveness, and importance of the COVID-19 vaccine. This study takes an integrative approach that includes a content analysis of COVID-19 vaccine-related messages from the CDC Facebook page and an experimental test of the effectiveness of the same types of vaccine-related messages on participants' attitudes toward the COVID-19 vaccine. Our findings from the content analysis show that gain-frame was used significantly more than loss-frame, and statistical evidence was more prevalent than narrative evidence in the CDC's COVID-19 vaccine-related messaging. Results from the experiment indicated that loss-framed, and messages with statistical evidence, may be more successful in promoting positive attitudes toward the COVID-19 vaccine.

Vaccine discourse during the onset of the COVID-19 pandemic: Topical structure and source patterns informing efforts to combat vaccine hesitancy

Background

Understanding public discourse about a COVID-19 vaccine in the early phase of the COVID-19 pandemic may provide key insights concerning vaccine hesitancy. However, few studies have investigated the communicative patterns in which Twitter users participate discursively in vaccine discussions.

Objectives

This study aims to investigate 1) the major topics that emerged from public conversation on Twitter concerning vaccines for COVID-19, 2) the topics that were emphasized in tweets with either positive or negative sentiment toward a COVID-19 vaccine, and 3) the type of online accounts in which tweets with either positive or negative sentiment were more likely to circulate.

Methods

We randomly extracted a total of 349,979 COVID-19 vaccine-related tweets from the initial period of the pandemic. Out of 64,216 unique tweets, a total of 23,133 (36.03%) tweets were classified as positive and 14,051 (21.88%) as negative toward a COVID-19 vaccine. We conducted Structural Topic Modeling and Network Analysis to reveal the distinct topical structure and connection patterns that characterize positive and negative discourse toward a COVID-19 vaccine.

Results

Our STM analysis revealed the most prominent topic emerged on Twitter of a COVID-19 vaccine was “other infectious diseases”, followed by “vaccine safety concerns”, and “conspiracy theory.” While the positive discourse demonstrated a broad range of topics such as “vaccine development”, “vaccine effectiveness”, and “safety test”, negative discourse was more narrowly focused on topics such as “conspiracy theory” and “safety concerns.” Beyond topical differences, positive discourse was more likely to interact with verified sources such as scientists/medical sources and the media/journalists, whereas negative discourse tended to interact with politicians and online influencers.

Conclusions

Positive and negative discourse was not only structured around distinct topics but also circulated within different networks. Public health communicators need to address specific topics of public concern in varying information hubs based on audience segmentation, potentially increasing COVID-19 vaccine uptake.

HPV and COVID-19 vaccines: Social media use, confidence, and intentions among parents living in different community types in the United States

Our study measured parental confidence and intention/uptake of two adolescent vaccines (HPV and COVID-19), focusing on differences among community types including urban, suburban, and rural. Although social media provides a way for misinformation to spread, it remains a viable forum for countering misinformation and engaging parents with positive vaccine information across community types. Yet, little is understood about differences in social media use and vaccine attitudes and behaviors for parents living in rural, suburban and urban areas. We sought to determine how to better reach parents living in different community types with targeted social media channels and messaging. In August 2021, we used a cross-sectional survey programmed in Qualtrics to collect data from 452 parents of children ages 9 to 14 living in different community types across the United States. Participants came from a survey panel maintained by CloudResearch. Survey questions asked about demographics, political affiliation, community type, social media use, health and vaccine information sources, and attitudes and behaviors regarding the HPV and COVID-19 vaccines. Our sample of parents (n = 452) most frequently used Facebook (76%), followed by YouTube (55%), and Instagram (43%). When comparing social media use by community type, parents used the top platforms at similar rates. Social media use was associated with vaccine confidence and intention/uptake in unadjusted models but not in adjusted models. Further, there were no significant differences in HPV vaccine confidence or intention/uptake by community type (i.e., rural, suburban, urban). For the COVID-19 vaccine, parents in rural communities were less likely to have vaccine confidence and intention/uptake in the unadjusted model. For both HPV and COVID-19 vaccines, political affiliation was the only common factor associated with both vaccine confidence and intention/uptake. Parents who identified as Democrat compared to Republican had greater confidence in the vaccines and had higher odds of vaccine intention/uptake for their children. Although rurality has been associated with vaccine confidence in the past we did not find that in our study. Instead, political affiliation appeared to explain most of the variation in vaccine confidence and intention/uptake, suggesting that more research is needed to identify best practices for using social media to reach parents with different political beliefs.

Parents' Use of Social Media as a Health Information Source for Their Children: A Scoping Review

BACKGROUND

Parents are increasingly using social media to inform health decisions for their children.

OBJECTIVE

This scoping review examines 1) How do parents use social media to find health information for their children? 2) What motivates parents to engage with social media to seek health information for their children? 3) How do parents seek to understand and evaluate the health information they find on social media, and how does social media impact parental health information-seeking?

METHODS

Scopus, CINAHL, Medline, PubMed, and Embase databases were searched, with open date parameters. Peer-reviewed studies that examined parents' and responsible caregivers' use of social media as a source of health information for their children (aged <18 years) were included.

RESULTS

The 42 included studies spanned 2011 to 2020. More than half (n = 24, 57%) were published in 2019 and 2020. Parents use social media for information about specific health concerns both before and after a medical diagnosis for their child. Parents are motivated to engage with social media as they seek out extensive information based on lived experience from other parents, as well as social support and community.

CONCLUSION

This scoping review reveals parents' motivation to use social media for health information, and how that can interact with, and impose on, clinical practice. It is important for those who provide pediatric health care to both understand and accommodate this permanent shift facilitated by social media, when working with parents who are seeking health information when making health decisions for their children.

Intención de vacunarse contra COVID-19 en la población de 40 años en adelante en México

Objetivo Evaluar el efecto de las fuentes de información sobre COVID-19, los beneficios y las barreras percibidas de la vacunación, y la actitud hacia la vacunación sobre la intención de vacunarse contra COVID-19 en la población de 40 años en adelante en México. Métodos Se desarrolló una investigación cuantitativa, transversal y explicativa. Se aplicó una encuesta electrónica a 703 personas de 40 años en adelante que residen en México. El análisis de resultados se realizó a través de la técnica de ecuaciones estructurales por medio del método de mínimos cuadrados parciales. Resultados Las fuentes de información sobre COVID-19 influyen positivamente sobre los beneficios percibidos de la vacuna y disminuyen las barreras percibidas. Además, los beneficios percibidos influyen positivamente sobre la actitud hacia la vacunación de COVID-19; sin embargo, las barreras no afectan la actitud. Adicionalmente, esta última influye en la intención a vacunarse contra COVID-19 e indirectamente las fuentes de información y los beneficios percibidos influyen sobre la intención a vacunarse mediados por la actitud.  

The prevalence and determinants of COVID-19 vaccine hesitancy in the age of infodemic

Background

Addressing COVID-19 vaccine hesitancy is key to ending the COVID-19 pandemic. Communication and media environments are potential drivers of vaccine hesitancy. It is worthwhile to examine the relationship between social media use and COVID-19 vaccine hesitancy.

Objective

This study aims to understand the prevalence and determinants of COVID-19 vaccine hesitancy.

Methods

Questionnaires were administered to 463 participants in mainland China. Factor analysis, correlation analysis, and linear regression models were utilized to examine the prevalence and influencing factors of COVID-19 vaccine hesitancy in China, as well as the relationship between social media use, media trust, health information literacy, and COVID-19 vaccine hesitancy.

Results

Lack of confidence and risk were identified as factors of COVID-19 vaccine hesitancy. Age, occupation status and income levels were significantly associated with COVID-19 vaccine hesitancy. In addition, we observed that frequency of social media use, diversity of social media use, media trust and health information literacy were significantly correlated with COVID-19 vaccine hesitancy.

Conclusion

Increased frequency and diversity of social media use, media trust and health information literacy can mitigate COVID-19 vaccine hesitancy and promote COVID-19 vaccination.

Behavioral Intention to Receive a COVID-19 Vaccination Among Chinese Factory Workers: Cross-sectional Online Survey

BACKGROUND

COVID-19 vaccines will become available in China soon. Understanding communities' responses to the forthcoming COVID-19 vaccines is important. We applied the theory of planned behavior as the theoretical framework.

OBJECTIVE

This study investigates the prevalence of and factors associated with behavioral intention to receive self-financed or free COVID-19 vaccinations among Chinese factory workers who resumed work during the pandemic. We examined the effects of factors including sociodemographics, perceptions related to COVID-19 vaccination, exposure to information about COVID-19 vaccination through social media, and COVID-19 preventive measures implemented by individuals and factories.

METHODS

Participants were full-time employees 18 years or older who worked in factories in Shenzhen. Factory workers in Shenzhen are required to receive a physical examination annually. Eligible workers attending six physical examination sites were invited to complete a survey on September 1-7, 2020. Out of 2653 eligible factory workers, 2053 (77.4%) completed the online survey. Multivariate two-level logistic regression models and ordinal logistic regression models were fitted.

RESULTS

The prevalence of behavioral intention to receive a COVID-19 vaccination was 66.6% (n=1368, conditional on 80% vaccine efficacy and market rate) and 80.6% (n=1655, conditional on 80% vaccine efficacy and free vaccines). After adjusting for significant background characteristics, positive attitudes toward COVID-19 vaccination (adjusted odds ratio [AOR] 1.20, 95% CI 1.15-1.25 and AOR 1.24, 95% CI 1.19-1.30), perceived support from significant others for getting a COVID-19 vaccination (AOR 1.43, 95% CI 1.32-1.55 and AOR 1.37, 95% CI 1.25-1.50), and perceived behavioral control to get a COVID-19 vaccination (AOR 1.51, 95% CI 1.32-1.73 and AOR 1.28, 95% CI 1.09-1.51) were positively associated with both dependent variables (conditional on 80% vaccine efficacy and market rate or free vaccines, respectively). Regarding social media influence, higher frequency of exposure to positive information related to COVID-19 vaccination was associated with a higher intention to receive a COVID-19 vaccination at market rate (AOR 1.53, 95% CI 1.39-1.70) or a free vaccination (AOR 1.52, 95% CI 1.35-1.71). Higher self-reported compliance with wearing a face mask in the workplace (AOR 1.27, 95% CI 1.02-1.58 and AOR 1.67, 95% CI 1.24-2.27) and other public spaces (AOR 1.80, 95% CI 1.42-2.29 and AOR 1.34, 95% CI 1.01-1.77), hand hygiene (AOR 1.21, 95% CI 1.00-1.47 and AOR 1.52, 95% CI 1.19-1.93), and avoiding social gatherings (AOR 1.22, 95% CI 1.01-1.47 and AOR 1.55, 95% CI 1.23-1.95) and crowded places (AOR 1.24, 95% CI 1.02-1.51 and AOR 1.73, 95% CI 1.37-2.18) were also positively associated with both dependent variables. The number of COVID-19 preventive measures implemented by the factory was positively associated with the intention to receive a COVID-19 vaccination under both scenarios (AOR 1.08, 95% CI 1.04-1.12 and AOR 1.06, 95% CI 1.01-1.11).

CONCLUSIONS

Factory workers in China reported a high behavioral intention to receive a COVID-19 vaccination. The theory of planned behavior is a useful framework to guide the development of future campaigns promoting COVID-19 vaccination.

Access to Vaccination Information and Confidence/Hesitancy Towards Childhood Vaccination: A Cross-Sectional Survey in China

Access to vaccination information could influence public attitudes towards vaccination. This study investigated the number and types of vaccination-related information sources, and estimated their associations with vaccine confidence and hesitancy in China. In January 2019, we conducted a cross-sectional survey in China, and 2122 caregivers with children <6 years completed self-administered questionnaires. Logistic regressions were used to assess associations between caregivers’ primary information sources and vaccine confidence/hesitancy. A majority (72%) of caregivers had multiple sources of vaccination-related information. The proportions of caregivers reporting professional sources, media, and peers as primary information sources were 81%, 63%, and 26%. Internal migrants were less likely to get information from professional sources; more educated and wealthier caregivers reported more information sources and were more likely to get information from media and peers. Caregivers who reported professional information sources had significantly higher odds of being confident about the safety of vaccines and lower odds of being hesitant toward vaccination than those who did not. Caregivers who reported the media as a primary information source had significantly higher odds of being hesitant toward vaccination than those who did not. To address vaccine hesitancy, it is essential to promote universal access to professional vaccination-related information sources, and to use the media to disseminate evidence-based information and clarify misinformation. Health communication should target internal migrants, and more educated and wealthier caregivers.

Parental Online Information Access and Childhood Vaccination Decisions in North America: Scoping Review

Background

Immunizing children throughout their early years prevents the spread of communicable disease and decreases the morbidity and mortality associated with many vaccine-preventable diseases. Searching online allows individuals rapid access to health information.

Objective

The purpose of this review was to develop an understanding of the existing literature of parents’ online health information-seeking behaviors to inform their vaccination choices for their children and to identify gaps in the literature around parents’ use of online health information and their vaccination choices.

Methods

A scoping review of peer-reviewed literature from Canada and the United States was performed. The following databases were utilized to perform the search: PubMed, CINAHL, Nursing & Allied Health Database, Scopus, and PsycINFO. The purpose of this review was to examine parents’ use of online information seeking related to vaccine information and to understand how parents utilize this information to inform decisions about vaccinating their children. Of the 34 papers included in the review, 4 relevant themes and subthemes were identified: information seeking, online information resources, online vaccine content, and trust in health care providers.

Results

Examination of the literature revealed conflicting information regarding parents’ use of social media and online resources to inform decisions around vaccinating their children. There is evidence of significant misinformation regarding vaccine risks online. Parents’ digital health literacy levels are unknown and may affect their ability to appraise online vaccination information.

Conclusions

Parents are seeking vaccine information from online sources. However, the influence of online vaccine information on parental vaccine practices remains uncertain.

Health Information Sources and the Influenza Vaccination: The Mediating Roles of Perceived Vaccine Efficacy and Safety

Although the influenza vaccine is widely recognized as an effective preventive measure, influenza vaccination rates among U.S. adults remain low. Moreover, influenza-related respiratory illnesses may increase the risk of adverse outcomes of COVID-19. Thus, this study examines the mechanisms involved in influenza vaccination uptake. Specifically, this study investigates how health information sources are associated with perceived vaccine efficacy and safety, which, in turn, associated with influenza vaccine uptake. Analyzing cross-sectional survey data from a national U.S. adult sample (N = 19,420), mediation analyses were conducted. Results revealed that considering vaccine efficacy, health information seekers who assigned more value to medical professionals, medical journals, and newspaper articles were more likely to perceive a vaccine as effective, thus being more likely to receive the influenza vaccine. By contrast, individuals who placed more value in social media were less likely to perceive vaccine efficacy, and, in turn, were less likely to get the influenza vaccine. Turning to vaccine safety, the value ascribed to medical professionals was positively associated with vaccine safety, which, in turn, related to influenza vaccine uptake. By contrast, social media, family or friends, and promotions were negatively associated with vaccine safety, and then influenza vaccine uptake.

Public health strategies adopted to manage the increase of accesses to vaccination services, as a result of the application of the law 119/2017

Background and aim of the work:

In response to the alarming reduction of vaccination coverage rates, Italian Ministry of Health approved the law number 119/2017, which has extended the number of mandatory vaccinations, for school attendance, from four to ten. The present study aims to evaluate accesses to the vaccination services of the Palermo Local Health Unit (LHU) and the variation of the vaccination coverage rates for hexavalent and measles, mumps, rubella and varicella (MMRV) vaccines, after the implementation of the law 119/2017.

Methods:

An extent of opening hours and an involvement of other health-care professionals in the vaccination services of the Palermo LHU have been adopted to manage the excess of accesses after the introduction of 119/2017 law and to limit the discomfort of general population. Vaccination accesses and coverage rates were calculated from the electronic immunization registers.

Results:

An overall increase of about 15% of single vaccination accesses was observed in the three semester after the introduction of the law in the LHU of Palermo. A peak of 35,516 accesses was observed during the second semester of 2017 (+ 30% compared to the same semesters of 2016 and 2018). From 2016 to 2018, coverage rates for full hexavalent cycle and first dose of MMRV, at 24 and 36 months, and for full MMRV cycle and fourth dose of diphtheria, tetanus, pertussis, poliomyelitis (DTPa+IPV), among 6 years old children, showed considerable increases.

Conclusions:

Law 199/2017 demonstrated a high efficacy in increase vaccination coverage rates also in Sicily. The synergy established between the LHU and the University of Palermo allowed an excellent management of the accesses to vaccination services, making it possible to respond to the public health needs of the general population.

Determinants of vaccine hesitancy and effectiveness of vaccination counseling interventions among a sample of the general population in Palermo, Italy

Counteract vaccine hesitancy is a public health priority. Main objectives of the cross-sectional study conducted were to evaluate knowledge, attitudes, and behaviors regarding vaccination issues, to estimate the prevalence of vaccine hesitancy and to estimate the effectiveness of vaccination counseling on community advocacy in a sample of general population. An anonymous validated questionnaire was administered in April 2017 at the main shopping center of Palermo and was followed by tailored vaccination counseling interventions. To estimate the effectiveness of the interventions four main connection parameters to the vaccinarsi.org website were evaluated, in the two months before and after the intervention and in the two months before the intervention compared with the same period of previous and following years. Among the 299 subject enrolled 12.7% were hesitant about vaccinations, and 4.7% declared being against vaccinations. General practitioners (GPs) and pediatricians were the most affordable source of information about vaccinations. A higher probability of vaccination hesitancy/refusal was reported among subjects who considered "alternative strategies" the best way for the prevention of infectious diseases (adj-OR = 7.01, IC95% 2.88-17.09, p-value < 0.001). A considerable increase of all the vaccinarsi.org website indicators analyzed was observed, from the area in which survey participants lived. Prevalence of vaccine hesitancy among population surveyed is consistent with the literature data. HCWs, such as GPs and pediatricians, should play a key role in modifying personal convictions and choices about vaccinations. A proper vaccination counseling could improve attitudes regarding vaccination issues, such as quality of web-based research.
