California is taking a stance against potential changes to the childhood vaccination schedule. This move comes in response to an executive order from President Trump. The order suggests altering the way certain vaccines are administered.

The president's order recommends separating the measles, mumps, and rubella vaccine into three individual vaccines. It also proposes giving all childhood immunizations at separate visits. California is defending its current vaccination schedule against these proposed changes.

Further details on California's defense and the potential impact of the executive order are available from the Los Angeles Times.
