Exclusive: NIH to dismiss dozens of grant reviewers to align with Trump priorities The move would undo years of work, leaving advisory councils understaffed, and without the full expertise needed for reviews.

NEW: In an unprecedented move, the NIH will soon disinvite dozens of scientists about to take positions on advisory councils that make final decisions on grant funding.

NIH staff were told to select others aligned with the Trump administration and told to expect placements by political appointees.

"No vaccine was tested more extensively than the RNA vaccines, and no vaccine was given to more people than the mRNA vaccines, & they were found to be incredibly safe...and effective. They saved 20 million lives, & they stopped a pandemic that was shutting down the world."

The problem with believing vaccines are dangerous is that by the time you realize you’re wrong, it’s too late and someone you love dies of a preventable disease.

Florida is about to find this out the hard way.

RFK Jr. rolled out that old chestnut again about how healthy Americans were in the 60’s, so here’s a fact check.

In 1965:

-42% of American adults smoked; it’s 11% now.

-The infant morality rate was 24.7/1000; it’s 5.6/1000 now.

-Overall life expectancy was 70 years; it's about 77 years now.

To have this paper appear the same day that RFK Jr is canceling all mRNA vaccine funding is further indication that irony is not dead, even though we might all be soon.

Senate appropriators approve Labor-HHS bill with NIH bump The vote and lawmaker comments show that most senators aren't going along with the White House's proposed 40% budget cut to NIH.

BIG NEWS:

“Senate appropriators on Thursday approved an FY26 Labor-HHS bill that included a slight bump in funding for the NIH, with a strong 26–3 bipartisan vote.”

Thank you to members of the Senate Appropriations Committee on both sides of the aisle!

The NIH budget will INCREASE by $400 million — not slashed by 40%, as Trump proposed — according to a proposal by Senate appropriators, says Sen Murray.

"Some have asked if there will even be an NIH by [2029]. The commmittee's resounding message is yes—Congress has your back", she says.

Extra kudos and thanks to all the staff at NIH and NSF and other federal funding agencies for working extra hard in very small windows of opportunity to get grants reviewed and funds released before the attention-addled federal policies change again (on an hourly basis).
