The initial tetanus does are much closer though. It's eventually every 10 years, but there's more than 1 before the first 10 year gap.The tetanus vaccine is the most similar I can think of to these vaccines but it needs a booster only every 10 years. As somebody (I think maybe you) said, this isn't like the flu shot because the flu shot is a different vaccine every year.
Maybe COVID ends up like that. Maybe it doesn't. Maybe we do end up needing boosters yearly or more often. But, nobody knows that today. We're at most what, 18 or 24 months since the initial doses in the initial study participants? And, more like 12 months for the first general use.
If we were looking at every 6 months forever being the end state, those initial study participants would already be on dose 4. Have we seen any studies about that?
When we start to see studies following the initial participants getting dose 5 or more, I'll start to worry about it being more frequent. They'll all need to get dose 4 before that, so we'll see it coming for months and not be a surprise.
We're obviously seeing lots of studies about getting dose 3.
Or, dose 2 if you're team J&J. Rest of you, bunch of pin cushions.
