Mr. Kennedy is wrong. Here’s my analysis of the health impact of the Gavi, the Vaccine Alliance alliance in saving under 5 child deaths, based on newest open access Institute for Health Metrics and Evaluation (IHME) estimates. The numbers = under 5 child deaths since Gavi was launched in 2000 to 2021. % reduction in deaths in parentheses.

The proposed recommendation to stop using the MMRV vaccine for young kids is the opening salvo in an attack on all childhood vaccines. The result will be dead children.

Secretary Kennedy made several claims yesterday in his statement to Gavi, including about the DTPw (diphtheria-tetanus-whole cell pertussis) vaccine. Accusing them of not taking vaccine safety seriously is misinformation, plain and simple.

🩺 While ACIP faces changes, medical evidence remains constant. New ACG guidelines reinforce that IBD patients need vaccines, screenings & preventive care. Trust your healthcare team—preventive health still matters most. ACG AJG - The American Journal of Gastroenterology Crohn's & Colitis Foundation Crohn's and Colitis Young Adults Network.

Pediatricians do not profit off vaccines. In fact, most pediatricians either break even or even lose money when they offer vaccines. Misleading parents about doctors' motivations puts children's health at risk and sows distrust in lifesaving vaccinations. nyti.ms/4lwVbM4
