There are ways to do things safely.

I'm comfortable enough knowing the efficacy of the vaccines and the biology of transmission with being outside without a mask.

It's preventing serious infections in those staff and players with the New York Yankees, those infections that occurred, the so-called breakthrough infections, importantly were for the most part mild to moderate infections.
