Please learn how vaccines work. No vaccine ever builds a filter in your nose to stop inhaling virus material.
ONLY function of vaccine is to create additional anti-bodies for a particular virus. If you inhale virus material, you will get infected vaccinated or not. But after you are infected, the additional anti-bodies will help kill the virus before it makes you seriously sick.
Changing the definition is meaningless.
Also, please understand that even though the fake vaccine may ease the effects of being infected with Covid, it won’t kill off the entirety of the virus. One could even argue that your body becomes a host that facilitates incubation and mutation - and retransmission.
