Boosters are extremely effective to stop the spread. A large percentage of those with at least 2 boosters experience no symptoms when exposed. However it is still important to continue to mask to protect yourself and others as boosters may not stop transmission, even if you never experience symptoms. Again, for most people covid will exhibit mild to no symptoms. It's our most vulnerable who are at risk from the unmasked and unvaccinated. So please, get your boosters and wear a mask.
