The COVID-19 pandemic posed severe challenges for governments, presenting unknown situations and requiring decisions to be made under unprecedented uncertainty. Scientists responded fast, developing vaccines to mitigate the effects of the disease and improve pandemic management. This study...

Background: Socio-economic inequality and vaccination inequity have long been critical issues. However, no studies have explored the gap in influenza vaccination uptake between public and private schools. Importantly, the extent to which socio-economic inequality translates into vaccination...

Background: Immunobiologicals are thermolabile products that require strict storage and transportation conditions to maintain their immunogenic efficacy, particularly in countries where logistical and operational challenges are evident, such as Brazil. Methods: A holistic multiple case study,...

We develop a population game with heterogeneous infection-loss types and social-circle mediated prosociality, where altruists internalize expected infection losses within a setting-specific circle. Equilibrium admits closed-form cutoff rules and an aggregate non-vaccination rate that reduces to...

he authors use county-level data to test whether an array of socioeconomic, demographic, political and religious variables explain COVID-19 vaccination rates. Results presented here build upon previous investigations of COVID-19 vaccine hesitancy in different contexts and are largely consistent...

Vaccines and seeds are the most significant resources in the poultry industry, particularly for chicken as a global staple. However, designing a resilient network for the poultry vaccine supply chain to create a viable poultry industry has been neglected. Hence, this paper contributes to the...

Childhood immunisation coverage in New Zealand has fallen since 2016, with the decline accelerating during the COVID-19 pandemic. Using administrative data from Stats NZ's Integrated Data Infrastructure, we examine determinants of immunisation uptake and how these have changed over time. We find...
