No. They used a smaller dose for kids, and it wasn’t good enough for them to even ask for an FDA review. They backtracked, decided that obviously the solution to an ineffective vaccine was more of the same, and continued the trial with very small statistics and came to some plausible numbers after adding a 3rd dose.

Good summary article on the vax for young kids, PFE vs MRNA.
two doses of the Pfizer vaccine, given 21 days apart, didn’t trigger a strong enough immune response in young children, and the company announced in mid-December it was adding a third dose to its regimen.
