Some if us weirdos are fighting back.

Their beliefs and their goals were right out in the open. We should have known that they would attack all aspects of public health.

You are not alone. And this is just the start. Is it wrong to be a conspiracy theorist when the conspiracy has been out in the open? MAHA, Project 2025 - it’s all out there. Thank you!

It may not have achieved our worst fears, but the erosion can still be effective if done incrementally. Great (but sad you had to do it) post.

🦠What happens when you say you will only protect babies of infected moms, but you are bad at detecting infected moms❓

🚫You miss a lot of babies who needed protection.

This is exactly why in 1991 we went from only vaccinating babies of Hepatitis B positive moms to vaccinating all babies.

“Am I muted, can you hear me?” I led a kickoff meeting while being hit by a norovirus once.

And who will be left out when the New Rules are put in place into place? But let’s talk about how these policies are race neutral.

RFK’s Anti-Vax Team Readies Its Next Moves “Their game is, let’s really destabilize trust in the vaccine, and make people really anxious about it.”

To be very clear, Kennedy's team is messing with a vaccine which has led to a 99 percent drop in the incidence of hepatitis B, which kills, early and painfully, 25 percent of the people who get it as children. lnk.thebulwark.com/3Xt957M

Look, I know that optimism isn't popular right now, but one way or another, by Trump breaking this system... he will strengthen it.

There's a long road of reform ahead of us & the collaborators who enabled him to break democracy must be expelled for that reform to occur.

But a reckoning IS coming.

A lot of us in the public health field are envisioning what accountability looks like while collecting receipts. It’s worth it to fight back.

Great, but depressing, piece by you and Dan. The plan to sow doubt in all vaccines by nibbling at the edges is in motion. I hate to be a conspiracy theorist, but the anti-vax people are following the path blazed by tobacco and fossil fuel companies. “Doubt is their product.”

Walking and moderate-weight dumbbells here. Warding off injuries from reaching for a piece of paper the wrong way and excess grandchildren lifting.
