The fear is that the USPSTF will go the same way as the CDC’s vaccine advisory panel.

Health and medical groups around the country are bracing for another grievous blow to America’s infrastructure of evidence-based health, this time targeting preventive medicine.

Earlier this week, health secretary and ardent anti-vaccine activist Robert F. Kennedy Jr. abruptly canceled a meeting of the United States Preventive Services Task Force (USPSTF), a scientifically independent panel of up to 16 volunteer experts that issues rigorous, evidence-based recommendations on preventive care—on everything from colonoscopies to folic acid supplements in pregnancy. The panel uses a highly transparent and rigorous framework, grading recommendations on an A to D scale. Recommendations with an A or B grade are adopted nationwide, and health insurance plans are required to cover them at no cost to patients.
