RFK Jr. went on national TV and spouted egregious, dangerous falsehoods about vaccines. As a parent and infectious diseases doctor, I couldn't stay silent. @FoxNews might not fact-check him, but I will. I've reviewed the trials. I've catalogued them. I have receipts. 🧵

Seattle-based researchers identified 4F11, a potent monoclonal antibody that neutralizes all major strains of human metapneumovirus, blocks infection in animals, and resists mutation better than existing options—making it a strong therapy candidate. biorxiv.org/content/10.110…
