I discussed this with my brother in law, who works in this field (and has for over 40 years).
The older you get, the more your body wears out (he says we’ll all die of some form of cancer, if something else doesn’t get us - your body’s repair mechanisms make more and more faulty cells, rather than the good ones).
Because of this, vaccines (and medications) can cause different reactions in older people than in those in younger age groups - this is why older people often need additional medications to counter-act some of the effects of taking medications which those younger than them don’t need.
So, they like to confirm that medications/vaccines won’t cause adverse effects in older people, rather than assume it (which is why the cohort I was in for the Novavax vaccine was mainly 60+).
