He's attempting to educate, here. He has to address a measles outbreak or he'll not be listened to by the vaxx lovers.

"While there is no approved antiviral for those who may be infected, CDC has recently updated their recommendation supporting administration of vitamin A under the supervision of a physician for those with mild, moderate, and severe infection. Studies have found that vitamin A can dramatically reduce measles mortality."

I read, "no approved antiviral" as a signal flare. And he's directing the public, specifically those who don't want the vaxxes, to vitamin A.

This opinion piece is a FANTASTIC start to MAHA.
