HOW THE rIGHT BECAME EVEN SILLIER THAN THE lEFT...:

For more than a decade, few places in the nation were associated with anti-vaccine movements as much as Marin County, the bluff-lined peninsula of coastal redwoods and stunning views just north of San Francisco.

This corner of the Bay Area had become a prime example of a highly educated, affluent community with low childhood vaccination rates, driven by a contingent of liberal parents skeptical of traditional medicine. Marin was something of a paradox to mainstream Democrats, and often a punching bag. In 2015, during a measles outbreak in California, the comedian Jon Stewart blamed Marin parents for being guilty of a "mindful stupidity."

But Marin is the anti-vaccine capital no more.

In the pandemic age, getting a Covid-19 shot has become the defining "vax" or "anti-vax" litmus test, and on that account, Marin County has embraced vaccines at rates that surpass the vast majority of communities in the nation. It comes after public health efforts to change parents' opinions, as well as a strict state mandate that students get vaccinated for childhood diseases.

And as the nation has grown more polarized, Marin residents are less comfortable wearing the "anti-vax" label increasingly associated with conservatives. Americans who identify as Democrats are more than twice as likely to be vaccinated and boosted against Covid -- and Marin County is one of the bluest enclaves in America.

"It kind of became the cool thing to do to get vaccinated," said Naveen Kumar, physician-in-chief for Kaiser Permanente San Rafael Medical Center.

Dr. Kumar said some Marin parents who were hesitant about the vaccines have been persuaded by their children's enthusiasm, which he has witnessed among his teenage son and his friends. "I could hear him talking about, 'Can you believe there's this kid in my class and he's not vaccinated?' he said. "You almost become a little bit of an outcast if you're not vaccinated."

.

Among children 5 to 11, 80 percent in Marin County have both of their Covid shots, more than double the statewide or national rates. The rate among those under 5 is more than five times the nation's.

Given that a fifth of elementary-school-age children here still have not gotten the vaccines, it is not clear that Marin holdouts have changed their minds. But anti-vaccine parents no longer feel as empowered to voice their opinions. The mood shift was pointedly captured by a local columnist, who declared in January, "Unvaccinated? You're not welcome in Marin."
