A group of people in a room all vaccinated is safer than a group of people half vaccinated.
The vaccine is not a boolean on off switch, it's a percentage wise improvement over nothing, and it compounds when those around are also vaccinated.
Please provide some citation for this outrageous claim that the point of a vaccine is to NOT provide immunity from infection.
"Vaccines can be prophylactic (to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogen), or therapeutic (to fight a disease that has already occurred, such as cancer)."
