It's my unfortunate experience, when I've had covid its a 6-12 hour affair that happens once every 12-24 months. My 3rd vaccine shot had me in bed for 3 days. Leading to continued vaccination being unsustainable. My wife has a similar experience to yours, and gets moderate to severe covid. She gets the vaccine every year to help avoid it - but still gets moderate COVID roughly once per 6 months.
It's unfortunate that the vaccine has such radically different outcomes within a single household, if it was a flu shot like experience I'd happily get it once per year.
at least the vaccine greatly reduce the severe conditions such as death.
Natural immunity has been proven time and time again to be much more longer lasting and more effective than vaccination. Once you had COVID, there is no reason whatsoever to force people to get vaccinated. That is simply anti-science.
