The effectiveness and safety of COVID-19 vaccines

Despite overwhelming evidence of the effectiveness and safety of COVID-19 vaccines from randomized trials and observation data, a sizable percentage of the eligible population in the United States remains unvaccinated (or partially vaccinated). How might vaccine hesitancy relate to the Grossman model? How does receiving the vaccine fit into this model and what are the tradeoffs (consider heterogeneity in vaccine hesitancy shown here; https://www.kff.org/coronavirus-covid-19/dashboard/kff-covid-19-vaccine-monitor-dashboard/ )? Are there any adaptations to the Grossman model you might suggest to align it more closely with observed hesitancy? Or other economic models you have come across that could explain vaccine hesitancy? For example: the Grossman model doesn’t account for differences in the perception of health benefits from consuming market inputs to the production of health. If an individual perceives the marginal health benefit of a market input to be small or even negative, this could change their perceived optimal allocation of time and money.
