> * Covid could mutate into a super deadly virus if it stays around

If the virus mutates so drastically as to become super deadly to children, how likely is it that current vaccines will make a difference?

They might not make a difference. The point is to stop it spreading now, so it hopefully never gets a chance to mutate into something much much worse.

That sounds like a calculation by poetic metaphors. There's always been a concern that mutations that cause greater virulence could shift death to younger people via a metabolism paradox like swine flu seemed to have. Death sounding drastic doesn't mean a more drastic genetic difference than the mutations so far.
