Logistic and linear regression models explored associations between predictors of interest and vaccine outcomes, with coefficients reported on the risk difference and risk ratio scales.</div></div><div><h3>Findings</h3><div>A total of 5180 respondents were surveyed, one-third of whom had at least one child aged 1–18 years. Having received at least three other preventive health services in the last year was associated with COVID-19 and Flu vaccination in all countries (Risk ratio (RR) 1.04–1.54) and with vaccine confidence in the US (RR 1.10). Having at least three health care visits in the last year and having a regular health provider were also associated with a higher likelihood of vaccine uptake and confidence in some countries. Being confident in one's ability to obtain and afford quality care (i.e. “health security”) had a positive association with at least one outcome in all countries except Mexico (RR 1.07–1.36) and with children COVID vaccination in multi-country regression. Having a regular provider was associated with a higher probability of HPV vaccination for children. Health system engagement and health security showed stronger associations with Flu than COVID-19 vaccination and with vaccine uptake compared to vaccine confidence, although these associations varied across countries. Trust in scientists and trusting the national public health agency were also strongly correlated with several vaccine outcomes.</div></div><div><h3>Interpretation</h3><div>Our findings highlight the links between health system engagement, health security, and vaccination rates.

The deployment of these platforms for novel vaccine development is influenced by a wide range of factors that must meet end-user needs for uptake, which includes cost, frequency of delivery and dependency on cold-chain storage. These factors can be identified by constructing a vaccine target product profile (TPP) that helps to direct the research effort towards the desired goal. The COVID-19 pandemic has exemplified how viral vectored and nucleic acid-based platforms can be rapidly deployed for population disease control. While successful for viral vaccines, the applicability of these platforms for bacteria is less well defined. Bacteria present different challenges to vaccine design from viruses due to their diversity and complexity. Other platform technologies are under development to address these challenges. The more we understand about vaccine platforms, the more adaptable they become, particularly for deployment across species with benefits for One Health. A Workshop was held at the 13th International Veterinary Immunology Symposium (IVIS) in South Africa in November 2023 to discuss the opportunities and challenges in deploying novel platform technologies for vaccine development against bacteria, particularly those that are affordable to low-middle income countries (LMICs).
