A new UConn study finds that COVID-19 vaccines provided better protection in people who experienced side effects. In addition, those who had COVID-19 before vaccines were available had better and more durable COVID-neutralizing antibodies.
The study tracked roughly 300 healthcare workers for about a year beginning just after vaccines became available in 2021. The healthcare workers were vaccinated and reported symptoms and prior infections. Researchers collected blood from the workers and checked the levels of protective antibodies.
