I'll be at home in bed, infecting nobody. And yes, I do wear a mask in public. I doubt their efficacy, but's not such an imposition that I will give it the benefit of the doubt. Injecting something of unproven safety into my body is an entirely different matter.
If that were possible, the flu would be eradicated already. You only develop symptoms for most transmissible respiratory infections after you've already been contagious for a day or so.
Maybe, if you're unlucky. In all likelihood, you'll be asymptomatic and spreading it to a bunch of other people without realizing it (which is most of the reason we're in this mess). Then those people do the same, get sick, and/or die.
You'd have probably infected people, including high-risk people, before you experienced symptoms. If you're vaccinated, you ~won't be infecting people.
