You know that the flu shot isn't 100% effective right? You also know that others don't get the flu shot.
But, what about other viruses that we don't have vaccines for? Rhinovirus? Other coronaviruses? All of them can kill.
Why weren't you wearing a mask in years past to protect from other infectious diseases since masks are so effective and you care SO MUCH?
I can wait
Absolutely nothing is 100 percent. That is not a fair level to demand. Millions get flu shots because they do not want to get the flu or pass it along. Those flus were nowhere as transmissible as Corona is. Nor were they are virulent.
