i know this anecdotal, here my personal recent family saga…
my elderly mom was in the hospital, she caught covid while there, not severe case, thank God.
so, my sister and i were visiting her daily, before we found out she had covid.
my sister, who is vaxxed and boosted, has come down with fairly severe case of covid, with lung congestion and vomiting.
i am not vaxxed and have not gotten it. i kissed my mom on the forehead and held her hands during my visits.
it's very weird.
