CDC Studies Suggest Slumping Flu Shot Protection
This season's influenza vaccine effectiveness (VE) rates against outpatient visits and hospitalizations may be lower than last season's, pushed in part by a viral mismatch between the vaccine virus and circulating strains, according to an interim CDC analysis. Based on U.S. surveillance network data from September 2025 to February 2026, estimated VE rates against influenza A- and B-related outpatient visits for adults ranged from 22% to 34%, and 30% to 41% for those ages 65 and older specifically, while rates against hospitalizations reached 30% and 31%, respectively, reported Patrick Maloney, PhD, of the CDC's National Center for Immunization and Respiratory Diseases, and colleagues.

Doctors Warn Of A Deadly Complication From Measles Outbreaks
The first sign came when Deepanwita Dasgupta was 5 and started stumbling more while playing at her home in Bangalore in southern India. The girl was always up to something, so her parents figured extra bumps and bruises were just symptoms of an active childhood. Maybe, they thought, it was ill-fitting shoes. Relatives described the unicorn-loving child as smart, affectionate, and occasionally rascally. Before she learned the alphabet, she had figured out how to find her favorite show, Blippi, on a phone. She was known to sneak butter from the fridge to enjoy a few finger licks. (Bichell, 3/13)
