I admit to not looking at things scientifically. What reasons do you see for avoiding Pfizer?
Sorry, I didn't mean to imply that
I would avoid Pfizer, or Moderna for that matter, and in fact I've put my name on a list to be notified when one of them is available for people like me.
I just meant that I could understand that some other people have said they'd prefer to wait and see what the other vaccines are like, since these first two vaccines require two doses (ouch! and gotta go twice!), induce strong reactions in some people (couple of days of fever, achiness), and a very small number of people have had allergic reactions (thought to be due to the polyethylene glycol in the packaging, not the mRNA).
But I've seen several claims from scientists and doctors that they themselves would take whichever was first available to them. Here's one short explanation of why:
https://khn.org/news/article/when-your-chance-for-a-covid-shot-comes-dont-worry-about-the-numbers/Although the mRNA vaccines have shown higher efficacy, they were tested under conditions of lower prevalence of the virus, and before the newer variants appeared. We have no way of knowing whether the J&J vaccine would have showed higher efficacy in those conditions, too.
Forget efficacy, and look at hospitalization and death. There were none in those vaccinated during the clinical trials of Pfizer, Moderna and J&J, so in that sense they're all equivalent.
