The interrelatedness of social-structural aspects and psychological features with vaccination intention provides the context to explore personal psychological features related to vaccination. Specifically, we focused on general decision making and vaccine-related dispositions, and their contribution to the intention to vaccinate, within post-pandemic circumstances, after the imposed possibility of choosing a vaccine brand. Our study aimed to map the function (promotive, protective, risk, vulnerability) of a set of personal psychological aspects in the intention to vaccinate among people holding different social roles regarding the vaccination. We surveyed three samples of people: healthcare providers (HPs), parents, and laypeople, within the post-pandemic context. Negative vaccine attitudes lower intention to vaccinate in all regression models (all βs ranging from −0.128 to −0.983, all ps < 0.01). The main results indicate that, regardless of the sample/social role, there is a shared attitudinal core for positive vaccination intention. This core consists of [high] trust in large corporations, government, and healthcare systems, as well as perceived consensus on vaccine safety/efficacy and experience of freedom (protective factors), and [low] vaccination conspiracy beliefs, trust in social media, and choice overload (risk and vulnerability factors, respectively). There are no common promotive factors of intention to vaccinate: for parents, perceived consensus on vaccines, and trust in corporations and the healthcare system, play such roles; for HPs, the experience of freedom is obtained as a unique promotive factor. In contrast, for laypeople, no unique promotive factors were found. Our findings provide insights into the function of psychological factors of vaccination intention across different social roles, particularly healthcare providers, parents, and laypeople, and emphasize the need for tailored immunization interventions in the post-pandemic landscape.

Introduction. The COVID-19 pandemic has significantly impacted global health, with Eastern Europe experiencing notable excess morbidity and mortality and vaccine hesitancy. This study utilized the Behavior Integration (BI) framework to identify barriers and motivators for COVID-19 vaccination and develop strategies to increase vaccine demand and confidence in Moldova, North Macedonia, and Serbia. Methods. A mixed-methods approach was employed, including qualitative interviews and quantitative surveys. The BI framework was used to integrate human behaviors with technical and operational considerations throughout the project. Results. A total of 2742 online surveys were collected in Moldova and Serbia, revealing significant barriers such as vaccine safety concerns (OR = 1.839, 95% CI: 1.328–2.547 in urban Moldova; OR = 1.990, 95% CI: 1.351–2.931 in urban Serbia), logistical challenges, and lack of institutional trust. Conversely, motivators included personal health concerns, recommendations from health care providers, and the desire to travel. The proposed social and behavior change strategy included a continuing medical education course that trained 2403 medical providers, with post-test results showing a 99% improvement in knowledge and confidence in applying the information, and collective engagement workshops for 3260 chronic disease patients and 842 pregnant women, of which 7% were vaccinated against COVID-19. Conclusions. The BI approach effectively identified and addressed vaccination barriers and motivators, leading to tailored strategies that increased vaccine uptake. Continuous stakeholder engagement, adaptive learning processes, and local organizations are crucial for refining program implementation, ensuring sustainability, and promoting public health.

The interrelatedness of social-structural aspects and psychological features with the vaccination intention provides the context to explore personal psychological fea-tures related to general decision-making and vaccine-related dispositions, and their contribution to the intention to vaccinate, within post-pandemic circumstances, after the imposed possibility of choosing a vaccine brand. The aim of our study was to map the function (promotive, protective, risk, vulnerability) of a set of psychological aspects in the intention to vaccinate, in people with different social roles regarding the vaccination. We surveyed three samples of people: healthcare providers (HPs), parents, and lay people, within the context of the after-pandemic. Negative vaccine attitudes lower intention to vaccinate in all regression models (all βs ranging from -.128 to -.983, all ps < .01). The main results indicate that, regardless of the sam-ple/social role, there is a shared attitudinal core for positive vaccination intention. This core consists of [high] trust in large corporations, government, and healthcare systems, as well as perceived consensus on vaccine safety/efficacy and experience of freedom (protective factors), and [low] vaccination conspiracy beliefs, trust in social media, and choice overload (risk and vulnerability factors, respectively). There are no common promotive factors of intention to vaccinate; for parents, perceived consensus on vaccines, and trust in corporations and the healthcare system play such roles, for HPs experience of freedom is obtained as a unique promotive factor. In contrast, for laypeople, no unique promotive factors were found. These results and guidelines for the promotion of positive vaccination behavior are further discussed.
