"Perhaps in San Mateo county we will soon find out if 100% (except for me) vaccinated will stop Covid"

Greetings, Robackrman; I'm down the road in Santa Clara county. I just went to the county website to see what percentage here are vaccinated. As of August 2nd, 78.2 percent of the population of the county (age 12 and over) have been fully vaccinated (84.3 percent with one shot). So - how do they know who has had it, and who hasn't? I guess I'm in a database for this. I wonder when there will be a knock on the door.

So - assuming these stats are real - about 15 percent of the adults I see are not vaccinated at all, and another 7 percent may have buyer's remorse. We need a secret handshake.
