Here are the latest immunization news highlights I can share right now, based on recent public updates:
-
RSV activity persists in parts of the U.S., with several health agencies recommending continued use of RSV preventive antibodies for high-risk infants through the end of the typical season in regions where RSV activity remains elevated. This situation has prompted updates to local vaccination schedules in some jurisdictions.
-
Measles activity remains a concern in multiple states, with thousands of cases reported in the first months of 2026 and ongoing efforts to boost MMR vaccine coverage through school-based clinics, walk-in events, and targeted outreach.
-
Influenza and COVID-19 vaccination campaigns continue to emphasize protection as variant circulation declines in some areas, with health systems advising continued vaccination for eligible groups to maintain population immunity.
-
Public-facing immunization resources and educational materials are being updated to support clinicians and the public in improving vaccination uptake, including new communication strategies and practice checklists.
What you’d like to know next:
- Are you looking for updates specific to a region (e.g., Canada, Ontario) or a particular vaccine (e.g., RSV, measles, influenza, COVID-19)?
- Do you want a quick summary of key dates (season end dates, upcoming vaccine recommendations) or more in-depth analysis with sources?
- If you’d like, I can assemble a region-specific briefing or pull the latest official guidance from health authorities.
