The state's overall vaccination rate appears sufficient to maintain what immunologists call herd immunity, or the percentage at which enough people are vaccinated to protect the community as a whole. But suburban areas have seen a decline in immunizations in the past decade, with some schools having immunization rates near 50 percent. Herd immunity for measles is between 92 and 94 percent, according to the U.S. Centers for Disease Control and Prevention.
Pan, who is a pediatrician, and Allen, whose father has polio, framed the legislation as a crucial public health measure, holding that the Disneyland outbreak is only a hint of what's to come if community immunity continues to drop.
California now joins West Virginia and Mississippi as the only states without a personal-belief exemption for vaccines. Medical exemptions will still be available for children with serious health issues. When considering exemptions, doctors may take family medical history into account.
Effective the 2016-17 school year, children whose parents refuse vaccination and are not granted a medical exemption must be home schooled. School-age children who currently claim a personal-belief exemption will need to get fully vaccinated by kindergarten and seventh grade, the state's two vaccine checkpoints. The law applies to both public and private schools, as well as daycare centers.
The California Assembly's Health Committee also approved legislation Tuesday requiring home daycare providers and daycare center workers to be vaccinated against measles, pertussis and influenza.
In a rare message accompanying his signature, Brown expressed his support for the new law.
"The science is clear that vaccines dramatically protect children against a number of infectious and dangerous diseases," Brown wrote. "While it's true that no medical intervention is without risk, the evidence shows that immunization powerfully benefits and protects the community." Wow, Gov. Brown is really smart, what happened? He didn't used to be this smart, back when he was dating Linda Ronstadt! LOL (ouch, that was kind of a read. hahahaha) Anyway, good logical thinking and good job Gov. Brown. hahahaha (And State Senators Pan and Allen too.)
