While cVDPVs are rare, they have been increasing in recent years due to low immunization rates within communities.

Is the Covid vaccine live?
The mRNA vaccines do not contain any live virus. Instead, they work by teaching our cells to make a harmless piece of a “spike protein,” which is found on the surface of the virus that causes COVID-19. After making the protein piece, cells display it on their surface.
