What's Next for California's Contentious Vaccine Law

17 01.07.2015 Инфо

Gov. Jerry Brown on Tuesday signed a hotly contested California bill to impose one of the strictest school vaccination laws in the country in the wake of an outbreak of measles at Disneyland late last year. 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. According to the U.S. Centers for Disease Control and Prevention, herd immunity for measles is between 92 and 94 percent. California now joins West Virginia and Mississippi as the only states without a personal-belief exemption for vaccines.
