No, since vaccinated people are much, much less likely to be infected. That matters. Just as a sober driver is much, much less likely to kill someone in an auto accident. That matters, too.
Then why do sober drivers need to wear a seat belt? You really don't know? Seriously?
Because the virus is much, much less likely to even exist in vaccinated people. Doesn't seem like a difficult thing to understand, does it?
You're less likely to get in an auto accident if the driver is sober. Less likely but not impossible.
Again... for the same reason sober drivers still have to wear seat belts. Think.
"A traffic safety engineer just stated, on the news radio, that sober drivers don't have to worry about drunk drivers."
No, I don't think so. There's still a small but significant risk that a vaccinated person can be infected. And if this guy is a doctor, he's a remarkably stupid one, since unvaccinated people are much, much more likely to be infected. And thereby are a hazard even if a small hazard to vaccinated people.
Yeah, that was more than a little stupid, wasn't it?
