and as a pediatrician, this is, of course, frustrating. but i think warranted. i think it's the best we know that happened here and everything we know, we know from press releases. none of us have seen the data. but what we know is that two doses may not have been enough to induce the immune response we're hoping to get in this age group. the efficacy is really what's at stake here and what we're hoping to gather more data on with this potential third dose. the safety, however, this is important to remember, the safety data is there and it's sound. it's safe. what we're waiting for is a potential third dose that will get the immune response that we want in this age group. >> so let me dwell on that point. people will say, the skeptics out there who spread misinformation all the time will say, ah-ha. ah-ha. there's no question about the safety of these vaccines. i've had four shots. i'm immunocompromised so i've been boosted. the question here is, is it two doses or three doses? what's the right formula? these are young children
