Results from 2 big GLP1 (Semaglutide) trials in early #Alzheimer announced: both failed
Disappointing for study participants, for patients, and for future drug development. Hopefully subgroup / post-hoc analyses can show something helpful in the months to come.

Vaccine preventable diseases literally KILL CHILDREN, there is NO EVIDENCE they cause autism & the fact that we’re even having this conversation in 2025 would be a FUCKING JOKE if it didn’t mean that kids who can’t help the fact that their parents are making BAD DECISIONS are ACTUALLY GOING TO DIE.

About 90,000 people living near larger chemical plants face an unacceptable risk of developing cancer, the EPA says.
New rules adopted last year could’ve cut that number to 3,000 residents — a drop of 97%.
But Trump has halted those efforts.

How awful. This is outright health disinformation, lying to the American people. Not only is there massive evidence showing no link between vaccines & autism, there’s not even a plausible mechanism based on what we’ve learned about the genetics of autism, some environmental exposures in pregnancy
HEADS UP: CDC website now officially asserts that vaccines may cause autism.“Studies supporting a link have been ignored by health authorities.” Also says the “vaccines do not cause autism” header remains b/c of an agreement with Cassidy.

they want to know your secret
