Trump’s vaccine plan would require millions of individual shots last used decades ago

President Trump issued an executive order this week calling for immunizations for measles, mumps and rubella, a mainstay of vaccination programs worldwide, to be offered as three individual jabs given at separate times, instead of in one combination shot.

His Health Secretary Robert F. Kennedy Jnr founded an anti-vaccine group and has long promoted a disproved link between the MMR shot and autism.

Recommendations from the US Centers for Disease Control and Prevention (CDC), the federal agency that sets vaccine guidance, remain the same.

The head of the World Health Organization (WHO) criticized changes to the U.S.’s vaccine policy for children on Wednesday.
