The State of US Vaccine Policy — Apr 28, 2026

HHS Secretary Robert F. Kennedy Jr. testified before Congress for nearly 20 hours, acknowledging the MMR vaccine's safety and effectiveness for most people, but refusing to commit to implementing new CDC vaccine guidance. The government has asked a judge to pause a case related to vaccine policy while it decides whether to appeal a preliminary injunction.
HHS Secretary Robert F. Kennedy Jr. recently testified before Congress for nearly 20 hours. He acknowledged that the measles, mumps, and rubella (MMR) vaccine is safe and effective for most people. Kennedy also conceded that vaccination could possibly have saved a child's life during the Texas measles outbreak. However, he refused to commit to implementing vaccine guidance from the new CDC director nominee, Erica Schwartz, without interference. The government has asked Judge Brian Murphy to pause the case American Academy of Pediatrics (AAP) v Kennedy while it decides whether to appeal a March 16th preliminary injunction. The government's move is notable because it didn't signal whether it plans to appeal, and the 10-day window to appeal may have closed.
