Special Issue Information

Dear Colleagues,

This Special Issue is a continuation of our previous Special Issues, entitled "Strategies to Increase Vaccination Coverage and Vaccine Confidence" (https://www.mdpi.com/journal/vaccines/special_issues/Vaccine_Confidence) and "Strategies to Increase Vaccination Coverage and Vaccine Confidence 2.0" (https://www.mdpi.com/journal/vaccines/special_issues/Coverage_Vaccines).

Vaccines are effective and cost-effective preventive interventions against infectious diseases occurring in children and adults. The importance of vaccines is emphasized by economic studies reporting that vaccines for children and adults are associated with low cost–effectiveness ratios and societal savings. Nevertheless, the percentages of vaccination coverage registered in developed and undeveloped countries in the target vaccination populations (children, adults, high-risk individuals, specific population groups) remain below the recommended levels. Vaccine hesitance, defined as a “delay in acceptance or refusal of vaccines despite availability of vaccine services”, is one of the factors explaining the suboptimal percentages of vaccination coverage. Vaccine hesitancy depends on the perceived risk of disease, accessibility of vaccines, and vaccine confidence. High confidence in vaccination programs is necessary to achieve high percentages of vaccination coverage. This Special Issue focuses on the strategies and practical solutions to increase the percentages of vaccination coverage by means of increasing vaccine confidence.

Background: In the last several decades, vaccine hesitancy has become a significant global public health concern. The human papillomavirus (HPV) vaccine has been on the United States of America (USA) market since 2006, with extended approval up to age 45 granted in 2018. To date, there is limited research evaluating barriers and facilitators related to HPV vaccine initiation among adults and the influence of the COVID-19 pandemic on individuals’ vaccine-related behaviors. This study’s main objective was to characterize the contributing factors that could promote or inhibit HPV vaccine uptake for adults. Methods: A qualitative approach consisting of focus group discussions (FGDs) was used for this study. The FGD guide was informed by concepts from the Transtheoretical Model, Health Belief Model, and Social Cognitive Theory. All virtual FGDs were led by two researchers, who recorded audio for data collection. The data were transcribed by a third party, and the transcripts were imported into Dedoose® software and analyzed using the six steps recommended by thematic analysis. Results: A total of 35 individuals participated in 6 focus groups over a 6-month period. Thematic analysis revealed four themes: (1) Intrinsic motivators for HPV vaccination, (2) Extrinsic motivators for HPV vaccination, (3) Vaccine promotion strategies, and (4) Impact of COVID-19 Pandemic on vaccine hesitancy. Conclusion: Both intrinsic and extrinsic factors play a role in influencing HPV vaccine uptake, and such considerations can guide efforts to improve the odds of HPV vaccination in working-age adults.

Background: Coverage rates of routinely recommended vaccines in older adults still fall below the targets established by international and national advisory committees. As a result, related diseases still have a high incidence, morbidity, and mortality. Information and Communication Technologies (ICT) could provide useful tools to improve immunization rates by bringing information directly to the target user at a relatively low cost. The present research aims to systematically review recent literature on interventions applying ICT to improve the uptake of influenza, pneumococcal, COVID-19 and herpes zoster immunization rates among older adults. Methods: Studies published in English between 1 January 2000 and 10 November 2022 were identified by searching electronic medical databases (PubMed, Scopus) and were independently reviewed by two different authors. A total of 22 studies were included in this review. Findings: Interventions applied the following ICT tools: phone calls, text messages, messages sent via personal electronic medical records, automated phone calls, remote patient monitoring in a home telehealth program and emails. In terms of the vaccines promoted, 11 studies prompted the influenza vaccine, four prompted the influenza and pneumococcal vaccines, three the pneumococcal vaccine, two the herpes zoster vaccine, one the COVID-19 vaccine and one both the pneumococcal and herpes zoster vaccines. Overall, more than half of the studies (n = 12) found some level of effectiveness of these ICT strategies in increasing vaccination rates among older adults, while five studies were partially effective (for specific vaccines or population subgroups), and five reported no significant effect. Conclusions: Prevention programs using ICT tools could be effective in promoting immunizations among older adults. Full article

COVID-19 caused significant morbidity and mortality amongst ethnic minority groups, but vaccine uptake remained lower than non-minoritised groups. Interventions to increase vaccine uptake among ethnic minority communities are crucial. This systematic review synthesises and evaluates behaviour change techniques (BCTs) in interventions to increase vaccination uptake in ethnic minority populations. We searched five databases and grey literature sources. From 7637 records identified, 23 studies were included in the review. Interventions were categorised using the Behaviour Change Wheel (BCW) and Behaviour Change Taxonomy v1. Vaccines included influenza, pertussis, tetanus, diphtheria, meningitis and hepatitis. Interventions were primarily delivered in health centres/clinics and community settings. Six BCW intervention functions and policy categories and 26 BCTs were identified. The main intervention functions used were education, persuasion and enablement. Overall, effective interventions had multi-components and were tailored to specific populations. No strong evidence was observed to recommend specific interventions, but raising awareness and involvement of community organisations was associated with positive effects. Several strategies are used to increase vaccine uptake among ethnic minority communities; however, these do not address all issues related to low vaccine acceptance. There is a strong need for an increased understanding of addressing vaccine hesitancy among ethnic minority groups. Full article
