Howie and Harlan discuss the end of flu season, vaccine effectiveness, and the challenge of rebuilding public confidence in immunization. Also: new cholesterol guidelines that push earlier treatment, measles outbreaks and the erosion of herd immunity, a court ruling pausing changes to vaccine guidelines, signs of stabilization at the NIH, new evidence on football and brain injury, and a MedPAC report suggesting Medicare Advantage plans are overpaid.
