@Pmason74 @Lynxblaine @stilletio1 (1/2) Hello. If you have had COVID-19 already, you may have some protection against reinfection (immunity) for several months, but you may still also carry and transmit the virus to other people. Evidence is now emerging that shows vaccines can reduce transmission.
