Appearing on NBC’s “Meet the Press,” Marshall, a physician, voiced support for ongoing coronavirus immunizations but appeared to also argue that not everyone needs a booster shot. He said protection offered by natural immunity from having contracted COVID-19 should also be taken into consideration.

“If the CDC could have pivoted sooner, we would have saved thousands of lives. I think being honest with people, the CDC needs to acknowledge natural immunity,” said Marshall. “Look, as a physician, I was never able to talk anybody into stopping smoking by a mandate or by trying to argue with them. It was by being honest and communicating with them.”

“Ninety-two percent of Americans have some level of immunity to this virus based upon the CDC website. So let’s start there. And, really, the messaging coming out of the White House has to acknowledge natural immunity and be honest with America,” he added.
