Greetings!

Finally, some good news. 

Late yesterday afternoon, a federal judge issued an important ruling in our lawsuit against Secretary Robert F. Kennedy and the federal administration’s dangerous changes to vaccine policy. This is a major victory—not just for MPHA, but for every family, every child, and every community that depends on the decades of rigorous, life-saving science behind vaccines. 

What this means. 

The judge’s order included three stays, meaning three administrative actions are now on pause: 

• The unlawful appointments made to the Advisory Committee on Immunization Practice (ACIP)—the expert body that guides CDC immunization policy—are frozen. 
• Any votes taken by the inappropriately reconstituted and unqualified ACIP members—are paused. 
• The revised childhood vaccination schedule issued in early January—which stripped critical vaccines from the federal recommendations without new evidence—is halted. 

The government may well appeal — but make no mistake, this is a HUGE victory. A statement from our Executive Director, Carlene Pavlos: 

Why this matters. 



When a federal judge issues stays like this, it signals that our case has merit—that we, alongside our co-plaintiffs at the American Public Health Association, the American Academy of Pediatrics, and others, are likely to succeed at trial. It also signals that the court sees real harm behind done to real people by this administration’s reckless actions. 

And beyond vaccines? This ruling asserts something we all need right now: a check on the power and impunity of this federal administration. 

How you can help. 

Please take a moment to read the press release and, if you haven’t already, yesterday’s Boston Globe article quoting MPHA’s Executive Director, Carlene.  We all need to celebrate wins, so share both with your friends and colleagues. 

One more thing, if you are excited about this ruling, join MPHA as a member today and be part of the fight. If you are already a member, consider an additional contribution or becoming a monthly donor to help fuel this work. MPHA can only take on this important work because of the support of our allies.   

In solidarity,

MPHA Staff
