Donald Trump signs a decree with new recommendations regarding vaccination, which calls for the vaccination of children to be reduced.

American President Donald Trump signed a decree on Monday with new recommendations regarding vaccination, which calls for the separation of vaccinations for children and made, in several instances, a connection to autism.

The decree recommends that the vaccines against measles, rubella, and mumps be separated, instead of being administered in a single injection, Donald Trump emphasized.

The Department of Health is set to establish Working Groups tasked with proposing these vaccines in individual form "in collaboration with the private sector and other countries, as appropriate."
