But the analogy to cars is flawed. A more equitable one would be to obey traffic laws and not do things like speed or lane jump. I.e driving in a responsible manner that is considerate of others safety. It doesn’t reduce traffic accidents to zero, it minimizes them. Your analogy would be like continuing the lockdown for vaccinated people because even vaccinated people can in rare cases spread the disease. That is as wacky as forbidden people to drive. Having people vaccinated to partake in large gatherings is like requiring people to obey speed limits or face a penalty. Sure some people will get around it.
At the same time employers now seemingly want to be on the hook for any communicable diseases spread on company property or function. People are being coerced into disclosing medical information or risk being treated like pariahs. It cannot be understated that people are being pressured into getting an unapproved (EUA is not approval) gene therapy (FDAs classification, not mine) that has never been widely tested in humans and has non-trivial side effects. This is unprecedented, at least in the US.
This is on top of being constantly mislead by media and government officials. NPR recently gave a stat, something to the effect of “young people under 40 make up half the positive COVID cases”. Sounds alarming, except that demographic makes up half the population _and_ that demographic had disproportionately mild symptoms from the disease.
If you want to be vaccinated, please go right ahead. But then stop. Allow others that you are not the guardian of to make their own health choices based on their personal research or decision making process.
It's now becoming obvious that vaccinated individuals can still be infected and can spread the infection as well. At the same time, mortality is greatly diminished. At that point, we have a vague and unspecific reduction of an already modest risk. This is insufficient to make a "civic responsibility" argument. By the same token, I could argue people should not drive cars as a matter of civic responsibility, because that carries a non-zero risk of killing a pedestrian.
