and shingles?
I didn't know about a pneumonia shot
Me either, I had to have a presurgical physical and the doc got me the shot, he said every year once you are over 65. He didn't really ask me either. Whatever.
The shingles vaccines (you get 2) are permanent, I hope, that is the one where I had a pretty bad reaction, it was brief fortunately, but not fun.
Shingles is not good to contract though, I should be good now.
As for how long a vaccine will last, we really don't know, we have T cells, as has been discussed, and you could have some level of resistance even with ABs below detection.
And the AB test can read positive because you had a cold recently, it's not as specific.
Pneumonia is of course a frequent killed of older folks, which I now am. I just got my first ever SS payment credited to my account. I was going to wait, but there is so much crap about the SSTF I pulled the trigger.
