Same here. No COVID shots, no flu shots, no shingles shots, no pneumonia shots, and pretty much no any other shots either. I did let them talk me into a tetanus shot about 5 or 6 years ago, because I hadn’t had one in maybe 50 years. When I was a kid, they’d give enormous tetanus shots which were supposed to provide lifelong immunity. Maybe they did; I never got tetanus despite plenty of dirty wounds along the way.
Rule of thumb is “if you can’t remember when you had your last tetanus shot...you need another one”.
It’s a good rule.
And I’m overdue.
