This study investigates the factors that influence individuals’ willingness to accept a combined COVID-19 and flu vaccine. The primary focus is on examining the impact of trust in health institutions, frequency of flu vaccine uptake, and COVID-19 vaccine uptake. The analysis further delves into racial differences to better understand variations among different racial groups. This study employs t-tests to compare the means of trust in health institutions, frequency of flu vaccine uptake, and COVID-19 vaccine uptake between individuals who are willing and unwilling to accept the combined vaccine. Additionally, a weighted logistic regression analysis is conducted to predict the likelihood of individuals to receive the combined vaccine, considering key independent and control variables. The t-test results reveal that individuals who are willing to accept the combined vaccine exhibit higher levels of trust in health institutions, more frequent flu vaccine uptake, and higher COVID-19 vaccine uptake. This pattern holds true across all racial groups. The logistic regression analysis demonstrates that trust in health institutions, frequency of flu vaccine uptake, and COVID-19 vaccine uptake significantly predict individuals’ willingness to accept the combined vaccine. Partisanship and demographic characteristics also exert influence on vaccine acceptance. Trust in health institutions plays a pivotal role in vaccine acceptance among individuals from all racial groups. Encouraging routine vaccination practices and leveraging existing vaccination campaigns can facilitate the adoption of combined vaccines. It is imperative to address racial disparities and tailor communication strategies to specific demographic groups to enhance vaccine uptake.
