COVID: Natural vs. Vaccine Immunity. Some people who haven’t gotten vaccinated against COVID-19 worry about the safety of the vaccines and say they’d prefer to get natural immunity.
These data further indicate that COVID-19 vaccines offer better protection than natural immunity alone and that vaccines, even after prior infection, help prevent reinfections. “If you have had COVID-19 before, please still get vaccinated,” said CDC Director Dr. Rochelle Walensky.
