Judge blocks HHS immunization policy changes
Change
On March 16, 2026, U.S. District Judge Brian Murphy in Boston blocked major parts of Health and Human Services Secretary Robert F. Kennedy Jr.'s changes to U.S. immunization policies.
Why it matters
U.S. District Judge Brian Murphy issued the decision on March 16, 2026. The court rejected a CDC proposal to reduce the number of shots routinely recommended for children. The court sided with medical groups that argued Kennedy and the agencies unlawfully reshaped federal immunization policies. The order bars the agencies from carrying out the identified policy changes.
Implications
- • CDC cannot implement the proposed reduction in routinely recommended pediatric vaccine doses.
- • HHS is restricted from enacting the blocked elements of its immunization-policy changes.
