BAKERSFIELD, Calif. (KERO) — President Donald Trump signed an executive order Monday overhauling the way childhood vaccines are recommended, including a plan to eventually offer the MMR vaccine as three separate shots. The order directs the federal government to move toward separating the MMR vaccine, which protects against measles, mumps and rubella. The administration says it wants those options developed while also keeping the combined MMR vaccine available. The combined MMR vaccine remains available, and the executive order does not require parents to separate their child's MMR shots. The executive order does not change California's school vaccination requirements, which are set by the state.
