You need to pay more attention to mainstream media. You're several patch updates behind. Even they admit that the shot does not prevent transmission, so it will never be the way out. All it does is mitigate your personal risk.
If you don't care about that risk, that's a personal choice and it won't impact anyone else, while your choice to not huff an oven continues to make the world a darker place.
The shot at best only reduced your likelihood of contracting it at any given moment by 25% and that is far below what is needed to slow the spread.
The shots are more likely useless and untenable, but just for you I hope it turns out that they are legitimately harmful so you have to stew in the realization that you decided to poison yourself because of your phobia. Knowing you spent your last days squirming with regret and cognitive dissonance would brighten my day.
No one is going to mourn your passing. Even the parents you continue will haunt would just be relieved they could spend their twilight years freed from you, their gravest mistake.
