“My hope is that it’s going to be within the next month or so and not much later than that, but I can’t guarantee that.” Fauci said younger children will likely need three doses, because two shots did not induce an adequate immune response in 2 to 4 year olds in Pfizer’s clinical trials.

“Pfizer plans to submit data to the Food and Drug Administration in the first half of 2022 if the three-dose study proves successful, the company announced in December. Pfizer said it did not identify any safety concerns with the 3-microgram vaccine doses in children 6 months to 4 years old. Adults receive two doses of 30 micrograms apiece as part of their primary series of shots.”
