What boosters would you recommend for someone who has had the J&J vaccine? A J&J booster? One additional mRNA booster? Two?
I think J&J is basically over.
Now, I admit we do not KNOW that the size of the antibody response translates into a better outcome - but that’s how to bet.
So - the responses to a single dose of mRNA (either one) following J&J is much higher than a J&J booster.
J&J was supposed to release their two shot data in March or April. But they fell in love with “one and done”. Their two shot study wound up looking really good - but six months too late, the world has moved on.
