We can't believe we have to say this, but POLIO IS REALLY BAD. RFK Jr.'s "independent" "expert" ACIP is destroying the foundations of our public health system. It cannot be clearer: if we want to save lives, we have to #RemoveRFKJr. Take action now: standupforscience.net/impeach-rfkjr
ACIP CHAIR’S COMMENTS — The head of Robert F. Kennedy Jr.’s panel of independent vaccine advisers recently questioned the necessity of the polio vaccine — spurring a sharp backlash from Democrats and public health experts.

“As you look at polio, we need to not be afraid to consider that we are in a different time now than we were then,” said Kirk Milhoan, chair of the CDC’s Advisory Committee on Immunization Practices, on the podcast “Why Should I Trust You?”

“Our sanitation is different, our risk of disease is different, and so those all play into the evaluation of whether this is worthwhile of taking a risk for a vaccine or not,” Milhoan, a pediatric cardiologist and a senior fellow at the anti-mRNA Independent Medical Alliance, added.

Milhoan also said that “we have to take into account” whether the U.S. is enjoying herd immunity, and whether the disease burden could go up “if we take away all of the herd immunity.”

Key context: Before the polio vaccine became available in 1955, roughly 16,000 polio cases occurred each year in the U.S., often paralyzing children. If polio vaccination rates dip, the U.S. could see the return of a disease that once caused widespread fear in America, critics of Kennedy’s advisory panel warn.
