Well, I had ET long before COVID vaccines were even thought about. I have had five, both Pfizer and Moderna, all of those in my eighties! I did not need COVID messing up my life.
The lucky ones who got the vaccine, when suggested, have likely saved many from COVID. I think with any disease, there are always possible odd side effects or unusual and largely unknown reasons for other complications. Vaccines have been around to protect from many, many illnesses. Polio, measles, and so on that have maimed and killed people in the past. Unfortunately, the ‘squeaky people’ against vaccines seem to get all the media coverage.
