Researchers analyzed data on 9060 family physicians to find a correlation between those with the largest share of unvaccinated patients, typically serving marginalized communities, who had less support in their practices. These physicians were more likely to be male, older, and work in fee-for-service models than the remaining 90%.
A new study found that younger people from high-income areas accessed vaccines ahead of schedule, particularly in New York City. This led to lower coverage rates in low-income areas with high proportions of older residents, resulting in higher mortality rates over the year.
