Tulom County reports some of the state’s Lower vaccination rates In the 2023-2024 school year, according to data released by the state public health department this week.
Only 89.8% of Tuolumne County kindergarten students are up to date, compared with 93.7% of kindergartens across the state. Only 93.1% of kindergarten students received their measles, mumps and rubella shots, which were significantly below the statewide average of 96.2%. California usually publishes vaccination rates for a few grades, including kindergarten, first and seventh grades.
Public health experts say the vaccination rate is 95%, sometimes called “herd immunity” and is often considered the gold standard for preventing diseases. Even a slip of one or two percentage points can create opportunities for the spread of the disease, which means that even if the vast majority of children are vaccinated, in areas where the immunity rate drops below 95%, it still takes only a few cases to trigger an outbreak.
California Reports declined last year Although strict laws make it difficult for parents to skip their children, there are strict laws in the share of kindergarten students. Among them is 16 counties, where measles immunity is already below the herd immunity threshold.
Richard Pan, a former state senator of Sacramento Democratic, said the increase in vaccine hesitation in recent years, coupled with widespread disinformation online and an increase in political divisions, could make encouraging immunization more difficult.
“We seem to be in the wrong direction,” Pan said. “We’ve always felt comfortable, like, ‘We’re OK.’ But we’re suddenly proving to people that it’s not OK.”
