Many parents with babies and young children see the shots as critical to resuming their pre-pandemic lives, without frequent disruptions to day-care schedules or family celebrations. AdvertisementThe Pfizer-BioNTech vaccine, which is for children 6 months through 4 years old, is three shots of 3 micrograms each, one-tenth the adult dose. But some of the FDA advisers said this week they believe three shots will be needed to protect adequately against omicron and its subvariants. The vaccine makers added a third shot to their trial, delaying vaccine availability by months. They said they learned lessons during the pandemic that would help them speed studies next time for young children and also for pregnant and lactating women.
