Why do they keep pushing the COVID vaccines and boosters then we still get multiple COVID virus'?

Even the president had two cases of the COVID-19 virus after getting multiple vaccines and boosters.

I just found out that an entire prison is on lockdown due to so many people sick with COVID.

They tell us we can still get COVID-19 after being vaxed, and that it will keep you from having to go to the hospital and getting a severe case of COVID-19.
How do we know this is true or just a selling point for BIG Pharma?

Actually it isn't a prison, but a rehabilitation center which holds prisoner's in it.
