A US senator has criticized President Trump's order on vaccines. Senator Bill Cassidy, a Republican, expressed his disapproval of the president's decision to administer separate vaccines for measles, mumps, and rubella. According to Senator Cassidy, this approach is problematic because it would require children to receive more injections.

He noted that parents would have to take their children to the doctor more times, which could be inconvenient. Further details on Senator Cassidy's comments are available from the source, including his interview on CNN's "State of the Union".
