All that being said, here’s the very worst-case scenario for what could happen next with measles, according to Steier’s calculations.

It’s unclear what a nationwide outbreak would mean for the vaccinated population, says Steier.

And yet “the only way that we can prevent measles is MMR,” says Steier.

Steier worries about a study that RFK Jr. has ordered to investigate the link between autism and vaccines, which will be headed by David Geier, a man who has been disciplined for practicing medicine without a license, has no advanced science degree, and has suggested for decades that vaccines cause autism.

“The recommendation is, sit pretty,” says Steier.
