Exposing Antivaccine Rhetoric Masquerading as Real Science

Patent‑Free COVID Vaccine Reaches 100 Million at $2‑3

Anti‑parasitic Drugs Aren’t Cancer Cures, Just Profit Scheme

The congresswoman is wrong. These anti-parasitic drugs do not treat cancer, they’re pedaled by wellness influencers because they are cheap to purchase in bulk, re-package and sell with expensive telehealth visits. It’s for their expensive homes and yachts. Most Americans...

Reassembling ACIP Is Wasteful Under Anti‑vaccine HHS

Look, reconvening ACIP in any form when you have incurious antivaccine activists/ideologues in charge at HHS = waste of U.S. taxpayer dollars. Until there are changes at HHS, there’s no point. For RFK Jr ACIP is meant to legitimize dangerous...
