Immunizations Updates: The Return of Measles (S13 Ep.84)

Welcome to our vaccine-focused mini-series, "Immunizations Updates"! Today we will use data from the United States' measles resurgence following the 2025 outbreak to explore what every pediatric provider needs to know as cases continue to climb. We walk through how measles slipped toward losing its elimination status, how today’s clinicians can rapidly rebuild their diagnostic instincts, and what early symptoms are most likely to be missed. We also break down high‑risk groups, key clinical clues, key references, practice tips, and highlights from Lyles & Carson’s recent 2026 reference for prevention and post-exposure prophylaxis for children with inflammatory bowel disease. Along the way, we’ll discuss practical strategies for vaccine advocacy, documentation, differential diagnosis, and post‑exposure management, giving you the tools to protect vulnerable kids and strengthen vaccine confidence in their communities.
