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.

“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.
