Declined significantly in childhood measles Vaccination rates come from the common-19 pandemic ahead of the United States, a study published on Monday found that coverage may vary widely within a state.
Looking at county-level data from 33 states, Johns Hopkins University researchers found that the MMR (measles, mumps, and rubella) vaccination rate dropped from 93.92% in the 2017-2018 academic year to 91.26% in the 2023-2024 academic year. The authors of the study said other states were included because they lacked vaccination data.
Of the 2,066 counties studied, vaccination rates fell in 78%. The study found that in only four of the 33 states (California, Connecticut, Maine, and New York) had an increase in average county vaccination rates.
The data show significant diversity across state-wide vaccination levels, which the study’s authors say could “help targeted vaccination strategies.”
This study is the largest Measles outbreak Since the 2019 wave, in the United States. According to the May 30 Centers for Disease Control and Prevention, there are 1,088 diseases nationwide.
Texas is an example of a state where vaccination rates vary from county to county.
"If the vaccination rate is just above 80%, it's the shock of the measles outbreak in West Texas, which shows how fragile the vulnerability in some of these areas may be," CBBS News Health News Public Health News said.
According to the Centers for Disease Control and Prevention (CDC), 96% of reported cases in the U.S. are unvaccinated or unknown vaccination status. measles, Highly contagious diseaseswhich may lead to serious health complications or death. Government agencies say the MMR vaccine is very effective and safe.
The CDC also reported that vaccination coverage in kindergartens decreased by school year, saying the rate of kindergartens in the U.S. has dropped from 95.2% in the 2019-2020 academic year to 92.7% in the 2023-2024 academic year.
The Centers for Disease Control and Prevention (CDC) says it can reach the cluster vaccine when more than 95% of the vaccines in the community are vaccinated, making the disease difficult to spread.
"There are a lot of counties that are well below 95% of counties, so in some pockets in the country, especially in the country, we are very susceptible to measles outbreaks," Goldell said.
