Several shots – including flu and Covid – lost their CDC recommendations under overhauls from the White HouseSeveral shots lost their recommendation from the US Centers for Disease Control and Prevention (CDC) after a judge’s stay against changes wrought by the Trump administration – which may affect access to the shots in some states. And no new vaccine recommendations may be made as long as the vaccines committee is halted.Access to existing vaccines – and the future development of new vaccines – has been increasingly called into question under the second Trump administration, as the now-halted Advisory Committee on Immunization Practices (ACIP) made controversial recommendations and health officials made unilateral changes to routine vaccines, with long-term and global implications.

Elections seem top-of-mind for the Maha movement as key polling indicates anti-vaccine views are a liabilityUS health officials appear to be shying away from voicing negative views of vaccines in public as November’s midterm elections loom and key polling indicates anti-vaccine views are a liability.Health officials have made unprecedented changes to routine vaccine recommendations in the past year – slashing one-third of the US childhood schedule, including the recommendation for hepatitis B immunization at birth. But even before a federal judge essentially invalidated these moves, officials haven’t championed their dramatic changes after Donald Trump’s pollsters recommended veering away from anti-vaccine ideology ahead of the midterms.

The 2025-2026 flu season is concluding with one of the lowest vaccine effectiveness rates in more than a decade, with the CDC reporting effectiveness of approximately 25-30% in preventing adults from needing medical care, according to data released Friday. A viral mismatch between the vaccine strain and dominant H3N2 variant that emerged early winter caused the poor performance, with vaccination proving more protective in children at around 40% effectiveness against medical visits. Despite low effectiveness, the CDC estimates 27 million illnesses, 350,000 hospitalizations, and 22,000 deaths from flu this season—substantially lower than the prior year's 40 million illnesses and 520,000 hospitalizations at the same point.
CDC interim analysis from September 2025 to February 2026 shows this season's flu vaccine effectiveness at 22-34% against outpatient visits for adults and 30-41% for those 65+, with hospitalization protection at 30-31%, due to H3N2 strain mismatch. The season saw 27 million illnesses, 350,000 hospitalizations, and 22,000 deaths, lower than last year's peaks but with 101 child deaths, 85% unvaccinated. Despite flaws, experts like Dr. William Schaffner stress shots prevent severe outcomes, with adult rates at 46.5%. Vaccination campaigns will target improved strains for next season.
