can i now get a booster with pfizer, if that s what is available near me? if i got pfizer, can i get moderna? if i got johnson & johnson, can i get either of the other two? so the new york times is reporting that it is expected that the new rule is going to be get whatever. boost with whatever. whatever you got originally, you can get any of the three as a booster. now, let s take a look at the study that started this off. this was the study that was announced at an fda vaccine adviser s meeting last week. what it found, it looked at 458 study participants, and they found that fipfizer and moderna recipients did well with any booster. folks who got johnson & johnson months ago, they got a better antibody response if you used a pfizer or moderna booster instead of a johnson & johnson booster. so the results of the study are sort of supplemented with what infectious disease experts tell me that it sort of makes sense.
