RFK Jr.'s claim that vaccines didn't save lives, sanitation did, is half right—and dangerously wrong.

While sanitation helped in the early 20th century, vaccines saved millions of lives in the later 20th century and reduced severe impairments like brain damage. More in @statnews.com

Now RFK Jr. is claiming vaccines don’t actually save lives. Here’s the math to show what he gets wrong.

Six of the nine Nobel Prize winners this year work in the U.S.
Three of the six were born outside the U.S., which is the pattern most years. No country has benefited more from welcoming immigrants from around the world.

I cannot overstate how remarkable it is that under GOP rule, US federal health regulations have been captured by fringe crackpots who espouse views that the vast majority of the US public—and nearly 100% of health professionals—reject.

Because of Florida's decision to phase out childhood vaccine mandates, many will die of preventable diseases like measles, chickenpox, tetanus, and diphtheria. This is regressive, bringing us back to the early 1950s when parents had to worry that their kids might die from diseases like polio.

Florida will work to eliminate all childhood vaccine mandates in the state, officials say

The study does not randomize birth control method. So I think it’s rather hard to control for selection effects.

Doesn't everyone feel overburdened with mitochondrial challenges at the airport though? Those TSA procedures are tough these days.

it's not for me to say what others should do with their careers, but economists thinking of quitting the Trump admin might want to time their departures to reinforce this collapse narrative.

How do you track what is actually implemented?

This is the reasonable conclusion. But why doesn’t Trump just come out and say so? He’s generally not that shy about declaring his stances.

“Whom does it help?” Should be a core question of government policy. This administration seems more likely to ask “who can I spite? Whose timidity can I exploit?”

I’m sorry to say but the claim that the US under Trump is going to provide Ukraine with militarily enforced security guarantees, is simply the newest version of the Trump will hit Russia hard with sanctions delusion. Neither will ever happen, but if it makes you feel better….

"Kennedy questioned the effectiveness of the vaccines…

'You can't control the amount of energy that everybody is getting," he said. "When you give a vaccine, you want to know exactly how much energy is because some people react very, very badly and can get very, very badly injured.'"
