Glad to hear your brother is back home. Hope he is able to recover and avoid the long term effects. I don’t think anyone who has been in the hospital takes this lightly or wouldn’t encourage others to get vaccinated or continue to take appropriate precautions.
My SIL is a charge nurse at the local Hospital. Hearing her first hand accounts (patient identity withheld of course) is likely the other factor fueling my bitch-fits relating to COVID counter-culture.
