President Trump has taken action once more to change how children in the U.S. are vaccinated against infectious diseases. On Monday afternoon, he signed a new executive order in the Oval Office.

This order recommends reducing the number of childhood vaccines suggested by federal guidelines. It also proposes splitting the MMR vaccine, which combines protection against measles, mumps, rubella, and chickenpox, into separate vaccinations.

Additionally, the order instructs the Department of Justice to encourage states to decrease the number of vaccines required for school attendance. These latest moves are expected to face legal challenges, similar to past efforts aiming for changes in the vaccine schedule for children.

During the signing ceremony, President Trump addressed the need for further studies on vaccines in connection with autism rates. This theory has been thoroughly researched and debunked by scientific experts.

The announcement was met with approval from vaccine skeptics and criticism from numerous public health specialists.
