It's a little bit like mixing and matching vaccines to get better protection (which some countries are forced to do because they don't have access to the best single vaccine).
> It doesn't matter in countries like the US where the vaccine is free to anyone who wants it
How about the medical bills for a life-altering adverse event? Are those free for anyone who has to pay them? These considerations matter when we're talking about administering a vaccine which may provide very slim or no additional protection over natural immunity. There has already been one study suggesting the second dose of Pfizer even reduces cellular and humoral immune response.
What they don’t mention is that previous infection alone is at least as good as vaccination alone. According to data from Israel, previous infection is about 6x more effective in fact. https://www.cdc.gov/media/releases/2021/s0806-vaccination-pr...
Given that, I don’t at all agree with the conclusion of that CDC study that you HAVE to get vaccinated if you had a previous infection.
Like when you get seriously ill with Covid and have to be hospitalized in the ICU? That's more likely than an adverse reaction to a vaccine, if we're assuming that everyone will get Covid at some point.
Only as far as we're talking about reinfections from currently known variants. We've seen that current vaccines are still pretty good against Delta despite not being tailored to it. Is it not possible for vaccines to provide immunity against a future variant that's much deadlier upon reinfection?
