trial looked like, as you said, jim, for the parents out there. there were more than 2,000 participants, all 5 to 11-ye11 years old. two-shot regimen like adults, except it is 10 any crow grams. 30 micrograms is for anyone over 16. this is a small dose. the trial showing robust neutralizing antibody response and another piece of good information that we heard from pfizer here that we re going to be keeping a close eye on, that they are expecting more data on infancy, on vaccines in infancy as early as the fourth quarter. all this positive of getting shots into the arms of children. kristen holmes, thank you. dr. jonathan reiner from georgia washington university. dr. reiner, always good to see
