Science isn't truth, it's the pursuit of truth. As public health comes under increasing attack, we must stay rooted in evidence, whether we're talking about vaccines, acetaminophen, or COVID-19. Our communities' health depends on it.

As critical as I am of the CDC right now, I know many dedicated experts are still there. If we could hear their voices—not just political appointees—I’d feel differently. But the current messaging isn’t science-based, so I can’t trust the CDC or FDA at this time.

Broad access to vaccines of all sorts is in jeopardy, former CDC director Rochelle Walensky warns in an Op Ed in @statnews.com. www.statnews.com/2025/09/16/r...

I’m a former CDC director. I’m deeply concerned about the future of vaccines in the U.S.

“I am deeply saddened for the agency I was honored to lead, for colleagues put in harm’s way, and for the quiet heroism of public health workers who are derided for political gain,” Rochelle Walensky ...

“Allowing [access to vaccines] to be limited based on anecdote, whim, or flawed research is reckless and irresponsible.”

That’s exactly what the CDC's ACIP risks doing. This isn’t just policy—it’s people’s lives.

Fear in public service doesn't always come as bullets—it can be threats, smears, or silence. I've felt it, and so have many of you. But courage means showing up anyway. You’re not alone. Take care of yourself. The work we do matters so keep going.
