My understanding is that is because they are children, so the doses are much lower. DTAP, for example, is one of the vaccines that kids need. It has a 5 dose schedule. But, an adult that was never vaccinated can get one shot of Tdap instead. Notably, the DTAP vaccine is 71% effective after 5 years[1]. Compare to the covid vaccine being 38% after 6 months[2].
