My neighbor’s SIL was anti-vax. Healthy, in his forties, ended up in ICU with COVID.
And my uncle almost died after getting his booster.
20 mins after her second shot, she thought that she was having a heart attack.
She had 16 relatives visit, for Christmas dinner.
Everyone there was vaxxed, some had boosters, except for 2, who were unvaxxed and previously had covid.
All now have tested positive, except the 2 unvaxxed, with natural immunity.
Her symptoms were 1 day of a scratchy throat.
That's it.
Despite many of her relatives being elderly and / or in poor health, no one has gotten very sick.
Of the dozen or so that have contracted covid, in the last year, that I know about, all have been vaxxed.
