Maybe. Whatever it was, it sure doesn’t come off as a reason to take another clot shot.
I know people who have had 3 and now say they are done with them. No more. It has finally dawned on them that never has there been any vaccine that they had to continually take over and over and still get the virus it was supposed to stop.
I took 3 shots and I was happy to take them. That said, it’s hard for the “experts” to justify that we take another shot. The question is that is the Omicron the last significant variant? In that case the “pandemic” is over. I suspect we’ll find out in 6-12 months because that is how long it’ll take for another variant to emerge to hit the world again.
