Proposing a campaign to ask US restaurants to admit only clients who can prove having been vaccinated.

I think we should not start this now. Many people in the US have not had a chance to become fully vaccinated yet — they became eligible for vaccination only recently. We should wait a month or two, until the time when everyone over 16 will have had a chance to be fully vaccinated.

A small fraction of Americans cannot be vaccinated, for medical reasons. Allowing them in will make little difference in public health, so restaurants ought to do so.

People under 16 can't get vaccinated yet, but in fancy restaurants only a few of the clients are so young, and there is no significant risk of transmission between them as long as they are few in number.

With these two exceptions, people who cooperate with public health measures, as much as they can safely do, will not be excluded.

Thus, the only people excluded will be those who intentionally refuse to join in putting an end to Covid-19 in the US.
