Who Should Test & What to Do Next
In recent weeks, a significant measles outbreak has emerged in Texas, marking the state's largest in nearly 30 years. As of March 21, 2025, 309 cases have been confirmed, primarily affecting children aged 5 to 17. Tragically, this outbreak has resulted in the first measles-related death in the U.S. since 2015. Notably, while the majority of cases involve unvaccinated individuals, there have been instances where vaccinated individuals have contracted the virus, underscoring the importance of verifying immunity.
Measles (Rubeola Virus): What You Need To Know
Why Are Vaccinated Individuals Still Contracting Measles?
With measles cases increasing in some areas, many adults are wondering:
Am I still protected? Your immunity depends on your age, vaccination history, and risk of exposure. The MMR vaccine is very good at preferring immunity but you need 2 doses to have full coverage.
Did you have 2 doses of MMR? Some patients may not have had two doses, depending on their age, or missed well child visits. Others, even healthy individuals occasionally do not "seroconvert" ,that is, make antibodies to the vaccine.. That is particularly true for immunosuppressed individuals.
Measles Vaccine Timeline 1959-1989
One of my favorite science bloggers, Katelyn Jetelina, of Your Local Epidemiologist, posted this helpful infographic recently:
Should I Consider Getting an MMR Booster?
If any of the following categories apply to you - then YES!:
Born before 1957? Likely immune due to natural infection, but testing is an option if you're unsure.
Vaccinated in the 1960s? If you received a killed-virus vaccine (used from 1963–1967), you may need revaccination. A blood test can confirm immunity.
Uncertain of vaccination status? If you don’t have records, received only one dose of MMR or were vaccinated outside the U.S., testing can clarify your protection.
Healthcare workers & frequent travelers? Those at higher risk of exposure should ensure full immunity.
Immunocompromised individuals? If you have conditions affecting immunity, checking your protection is important.

Please note that you DO NOT HAVE TO CHECK. An MMR booster is safe and effective. However if you would prefer to check first, we can do provide that option
