Thanks to various unjustified vaccine phobias and skepticism, only one in three kindergarten classes in Arizona’s public and private schools have sufficient “herd immunity” to fend off the spread of measles through the student populations if a student gets infected with the virus, the Arizona Republic reports.
Nearly 33% of private schools reported sufficient populations of students being inoculated, while public school rates surpassed 35%. Just 17% of charter schools in the state reported having a high enough percentage of kindergarteners vaccinated against measles.
