My friend is in the hospital due to Covid. Yes had many underlying issues, however, contracting Covid sent him to the hospital. He is not vaccinated. He is one of a few hundred thousand who can’t take the vaccine. I won’t say why, but his Healthcare provider advised against it.
I know many past military veterans who cannot take the vaccine. They have nerve issues and other health concerns that precludes it.
Vaccinated or not, I will wear a mask until further notice. I like them actually, especially in the winter! Yes, nothing like a warm nose!
