Once most kids can be vaccinated, I'd like to hope we'll be at the end of this and can move on for good. I understand trials in such vulnerable groups is harder to do, hence why it's taking time. Lots of ethical, legal and health challenges to deal with.
They have been working on a phase 3 study since at least the spring for younger children with the Pfizer vaccine. I imagine it's taking longer because young children have not been infected at the same rate as older adults. Course that may change.
Right now Pfizer is planning to submit for FDA emergency authorization for the 5-11 cohort by the end of September, and the 0.5-4 cohort "shortly thereafter". I expect Heath Canada authorization requests would follow fairly quickly after those, so we might be looking October-November approval for 5-11 and maybe December-January for 0.5-4. At a guess!
(And, yes, Moderna is running trials for the same age groups as well.
