so we'll always have more data on safety and the effectiveness if we stick with the same vaccines. i stuck with pfizer. i would probably recommend doing the same with moderna, if you got two moderna doses. stick with moderna. the one gray zone may be those who got a single dose of the j&j vaccine. there's e merging data that a second dose looks really good and always looked that way from the phase one trial and gives robust effectiveness when you give t in two doses. i think the one study that's kind of spooking a lot of people is there was a preprint that suggested those who got the johnson & johnson vaccine when they got that second dose, they did bet were one of the mrna vaccines. i bead a little careful about that because, you know, the kinetics of the immune response with the j&j vaccine is a bit different. the peak in immune response tends to be delayed, and you also see more t-cell responses with the two doses of the j&j that you might see with the
