Very interested if you have a source for this claim, as I have been looking for one.

44% reduction after 6 months is not great but that's still significantly better than under 20% for preventing symptomatic cases which you have for a 2 dose vaccinated person facing Omicron half a year later.
However I am not sure if we had started this pandemic with Omicron and a 44% effective vaccine, that we would have put all our eggs in one basket the way we have to date. Hindsight is 20/20, of course.
You aren't crazy. Here's some actual data from the CDC: a child is at least 25 times less likely to be covid hospitalized than an adult under age 50, and 74 times less likely than an someone over age 50. Important caveat that this data is pre-omicron. https://www.cdc.gov/mmwr/volumes/69/wr/mm6915e3.htm
>most people have family or friends who are vulnerable and need to be protected
Couldn't agree more.
