Vaccinations have been touted as being 95% effective, but ISTM that by all indications actually having had covid is a lot more effective than that. I would venture at least 99% effective, based on people I know (and know of) who have gotten or not gotten covid over the past 10 months or so.
My parents are getting vaccinated today. Personally, if I were them I wouldn’t do it, because they have both had covid before and have tested positive for antibodies pretty recently. But I didn’t say anything to them because they were both pretty miserable when they got it and want to do everything possible to avoid suffering a similar fate or worse again.
But I have a young relative who is concerned about this in her own case. She also had covid, but she is training to become a nurse, and as part of her program needs to work in a hospital, and needs to be vaccinated. But she is pregnant, and is unsure of the effects of vaccination on her baby, and while it’s probably low risk it may not be zero risk, and she feels if she already had covid there’s no reason for her to get vaccinated now. But some big shot in the program she’s in said there would be no exceptions for people who already had covid, because they don’t recognize having had covid as being a valid protection against covid.
The sense I got from what that guy said - as it was relayed to me - was that it was one of these overly rigid scientific standard things. There had been published peer reviewed scientific studies on the effects of vaccines and there had not been comparable published studies on the protective effects of having had it, so we recognize one and not the other, despite what appears to be overwhelming empirical evidence. (But I might have gotten it wrong.)
There was an article in the WaPo this morning about the topic. I only read whatever they send me in an email, and did not read the actual article, but the general gist is that you never know how long immunity lasts and also from a public health standpoint it’s difficult to verify who did or did not have it. So they say public health experts are recommending that everyone get the shots but that people who have had it could voluntarily hold back while there are other people on line for it.
