I've heard that but then why do people say we need to get vaccinated to protect the most vulnerable members of society if the vaccine isn't actually slowing the spread and doesn't prevent infection?

EDIT:

To be clear I already had COVID and didn't have any serious symptoms so the argument about a hospital bed doesn't necessarily apply to me. Beyond that I actually got vaccinated, my question centers around the disparity of treatment we are giving individuals who are vaxxed and those who are not if both are capable of spreading. Further it brings in the question of vaccine mandates if they are much less effective then we were led to believe.
