Andrew Badley, M.D., COVID-19 Research Task Force Chair, Mayo Clinic: What we know the vaccine does is it prevents symptomatic disease. What we don't know if it does or not is to prevent infection. And if you are infected, but you don't get sick because of the vaccine, you can still replicate the virus and transmit the virus.
Currently, our recommendations are that if you've received the vaccine you still wear a mask, maintain social distancing, frequent hand washing, and avoid gathering in large social circumstances.
A generous benefactor has pledged $1 million and challenged us to raise an additional $250,000. Help us reach our goal!
