ST. LOUIS A data analysis by St. Louis University researchers shows just how much COVID-19 vaccines have prevented infections: The researchers found that, on average, for each additional percent of a county s population that received a first dose of vaccine, there were four fewer weekly infections.
The data was released Monday on the website medRxiv, where researchers post study results of urgent interest, prior to peer review.
Enbal Shacham, a professor at St. Louis University s College for Public Health and Social Justice, and the lead author, said the analysis has been submitted to an academic journal to be considered for publication.
