So glad @joho.bsky.social responded to this article. It's easy to call for scientists to be fair, balanced & ready to engage w/ respect when people are 'just asking questions'. The problem is it's followed by threats, attacks & chaos if they don't agree! sciencebasedmedicine.org/wanqtgambit/

The “We’re Not Allowed to Question This” Gambit
Anyone who truly values open and rational discussions about controversial subjects need to be cleared-eyed about where the threat to such dialogue is coming from.

The Hepatitis B vaccine was expected to prevent 9.5 million infections, 2.4 million chronic cases, and save 600,000 lives in the US by 2050. The federal vaccine committee has blood on their hands.

Sec. Kennedy must appear before the HELP Committee to explain why his vaccine advisory committee, in strong disagreement with the medical & scientific community, voted to end a decades-long recommendation that newborns receive the hepatitis B vaccine. This vaccine saves lives.

“ACIP has recommended a universal birth dose of the hepatitis B vaccine since 1991, after realizing a risk-based strategy wasn’t working. Annual hepatitis B infections among infants and children have dropped 99% from 16,000 to less than 20.”

If you want an idea of what RFK Jr & Jay Bhattacharya will do to the NIH, the chapter of Project 2025 on the NIH gives you a decent idea They will "END WOKE AT NIH"! NO MORE GENDER EQUITY ON SCIENCE PANELS! BRING BACK MANELS! Yes, this is from the actual document (tinyurl.com/2tertwfe)
Quotation from Project 2025:  "Woke Policies. Under Francis Collins, NIH became so focused on the #MeToo movement that it refused to sponsor scientific conferences unless there were a cer- tain number of women panelists, which violates federal civil rights law against sex discrimination. This quota practice should be ended, and the NIH Office of Equity, Diversity, and Inclusion, which pushes such unlawful actions, should be abolished."

COVID vaccine programs cost Ontario around $3 billion Canadian in 2020-2022. They prevented $3.1 billion in ICU-related economic losses alone. This doesn’t include non-ICU hospitalizations. We literally made $100 million by vaccinating people to keep them out of the ICU.
