Vaccines drive the evolution of more virulent covid strains. Vaccinated people infected with delta have measurable viral loads similar to those who are unvaccinated and infected with the variant. They don't get as sick but spread the virus nearly as well as unvaccinated folks. The spreading rate is correlated with the mutation rate.

A good mask, N95 or above, can prevent covid transmission and contraction. Cloth and surgical masks on the other hand are like trying to stop mosquitos with a chain link fence.

People that have the vaccine and walk around indoor spaces without a mask are actually causing their own eventual demise, as they will be giving the virus hosts (themselves included), allowing the virus to mutate to its next more virulent form that vaccines have no chance against.

I know it's painful to wear a good mask as you cannot show off your pretty face. Do it for your country, for Biden and for our hero Fauci. :-)
