Measles Cases Climb Past 1,790 — Why MMR Matters Right Now

What this spring's outbreaks mean for your family

The CDC has confirmed nearly 1,800 measles cases across the U.S.

so far in 2026, with most patients being children who were unvaccinated or whose vaccine status was unknown.

The good news: two doses of the MMR vaccine are about 97% effective and remain the strongest protection.

Now is a good time to check your child's records and call your pediatrician with any questions.

Clinic Takeaway

With outbreak-associated cases making up the vast majority of 2026 measles infections, proactive recall is high-yield. Run a registry query for patients overdue on MMR (especially 12-15 months, 4-6 years, and unvaccinated travelers) and send a short, reassuring message inviting them in. Post visible 'call before arriving' signage and refresh staff on the AAP 'Think Measles' triage workflow to protect waiting rooms.
