There is NO FUCKING EXCUSE for this to be happening.
I had a baby die in my arms of pertussis some fifty years ago. It was a HORRIBLE death. But my fellow nurses said to me, "It's almost stamped out now, they're all getting the shots, we won't be seeing this again."
HOW THE FUCK ARE WE HERE. 😡

A third infant has died in Kentucky, KYDPH adds:
“These are Kentucky’s first pertussis deaths since 2018. None of the infants nor their mothers received the recommended pertussis vaccinations during pregnancy or early infancy.”

@davybrenda.bsky.social and I’s UPF RCT is finally published!
We tested the effects of a eucaloric UPF vs no UPF diet on energy intake in young people.
Our age subgroup analysis found adolescents ate more in a buffet meal after the UPF diet. 🧵🧪
