Too many people were looking forward to enjoying the day maskless; it would have been demoralizing and infuriating after 150 million vaccinations for the feds to suddenly turn around at the last minute and ask them to cover up at the barbecue. It’s after July 4 now. Cases, hospitalizations, and deaths are rising in the U.S. again thanks to the B.1.617 Delta variant. And so the era of precautions has officially resumed in America’s biggest county.

Which makes sense. A germ that’s very transmissible will need to have nearly every vector of transmission blocked to keep it from eventually reaching an unvaccinated person. For a super-contagious virus like the one that causes measles, upwards of 95 percent of a group needs to be vaccinated to give the other five percent a reasonable shot at avoiding infection. Initially we were told that immunizing 60-70 of the population from SARS-CoV-2 might be expected to provide herd immunity. Then Fauci admitted that he had told one of his little white lies about that, that the true threshold was probably more like 75-85 percent.
