Why This Matters
As of July 16, the CDC confirmed 2,260 measles cases in 2026, spread across 44 jurisdictions and 34 outbreaks. The Johns Hopkins tracker showed 2,295 cases as of July 22. The November PAHO review of U.S. measles elimination status is approaching. August and September are historically peak travel months when transmission risk is highest.
The MMR vaccine is the only reliable protection against measles. Two doses provide approximately 97% protection. One dose provides approximately 93% protection. The vaccine is safe, effective, and widely available, often for free, at locations most Americans can reach this week without an appointment.
The most important thing many readers can do today has nothing to do with tracking case counts or monitoring outbreak maps. It is simply confirming that they and every member of their household have received two documented MMR doses, and getting vaccinated if they have not.
What We Know So Far
The CDC's measles case data are confirmed, laboratory-verified infections, not estimates. The 2,260 cases as of July 16represent a national emergency by the historical standards of a disease that was declared eliminated in 2000. Ninety-three percent of cases are outbreak-associated, and nearly all involve unvaccinated or under-vaccinated individuals.
South Carolina leads all states with 670 confirmed cases, followed by Utah with 518 and Texas with 182. Michigan, Ohio, and Florida also appear among the more significantly affected jurisdictions. Cases have been reported in 44 of the 50 states plus Washington, D.C.
Summer travel is a documented accelerant for measles spread. Unvaccinated travelers who encounter measles in one location carry it to communities in other states and countries. The CDC, in its travel guidance, continues to recommend that all travelers be up to date on MMR before departing.
Where Vaccination Is Available Right Now
County and state health departments are the most consistent, lowest-cost source of MMR vaccination. In every state with active measles outbreaks, health departments have expanded vaccination access. Most offer walk-in or same-day appointments.
In Utah, the Utah County Health Department has run drive-up MMR clinics offering the vaccine free while supplies last. The Southwest Utah Public Health Department offers MMR vaccination on a walk-in basis. The Utah Department of Health and Human Services has issued guidance encouraging clinicians throughout the state to offer MMR to all individuals over one year of age given the current active outbreak.
In Texas, Austin Public Health offers MMR vaccination at its Shots for Tots and Big Shots clinics and at additional locations across the city. HEB pharmacies in Texas are offering MMR with no copay for people 14 and older. Harris County Public Health and the Houston Health Department offer MMR vaccination, with same-day appointments available by calling 832-927-7350.
In South Carolina, CVS Health mobilized more than 200 locations statewide during the outbreak to offer MMR vaccination, according to a December 2025 press release, and pharmacy vaccination access remains active.
National Access: Pharmacies and Federally Qualified Health Centers
CVS MinuteClinic and CVS Pharmacy: MMR vaccination is available at select MinuteClinic locations. Walk-ins are accepted at most locations; appointments can be scheduled at cvs.com. Patients ages 3 and older can receive the vaccine at CVS Pharmacy locations. MinuteClinic provides the recommended second vaccination to children aged 4 to 6 years.
Walgreens: MMR vaccine is available at Walgreens pharmacy locations. Schedule through the Walgreens vaccine scheduler online or walk in at most locations.
Walmart Pharmacy: MMR vaccination is available at many Walmart pharmacy locations. Call ahead to confirm availability at a specific store.
Costco pharmacy locations: Offer MMR vaccination to both members and non-members. Call ahead to confirm availability.
Federally Qualified Health Centers (FQHCs): These community health centers serve patients on a sliding-fee scale based on income. No one is turned away for inability to pay. Find an FQHC near you at hrsa.gov.
Vaccines for Children (VFC) program: Children 18 and under who are uninsured can receive the MMR vaccine at no cost through this federal program. Any participating doctor or health department can administer VFC vaccines.
Vaccines.gov: The official U.S. government vaccine finder at vaccines.gov allows you to search by ZIP code to find all nearby providers offering the MMR vaccine, with filtering by cost and walk-in availability.
What Doctors and Experts Say
Dr. Natasha Bagdasarian, MDHHS chief medical executive, stated during Michigan's measles response: "The MMR vaccine remains our best defense, and two doses of MMR offer 97% protection against measles."
The CDC and the American Academy of Pediatrics (AAP) recommend two doses of MMR for all children. The first dose is given at 12 to 15 months; the second at 4 to 6 years. Children in outbreak areas may receive an early dose starting at 6 months of age, though that early dose does not count toward the standard two-dose series.
Adults born before 1957 are generally considered immune based on prior infection. Adults born in 1957 or after who have not received two documented doses should receive at least one dose unless they have documented measles immunity by blood test.
What the Evidence Shows and What It Does Not
The two-dose MMR vaccine series is one of the most thoroughly studied and most effective vaccines in clinical history. Two doses provide approximately 97% protection against measles. The vaccine's safety profile is well established across billions of doses administered globally since 1971.
The MMR vaccine does not cause autism. This claim was based on a fraudulent 1998 study by Andrew Wakefield, whose medical license was revoked. Numerous large-scale studies involving millions of children have found no link between the MMR vaccine and autism spectrum disorder.
A small number of people (approximately 3 in 100) who receive both recommended doses may still contract measles if exposed to a highly contagious strain in a low-vaccination community. No vaccine provides absolute protection in all circumstances, but two-dose MMR recipients who do contract measles typically experience milder illness.
MedicalDaily Evidence Check
- Data source: CDC Measles Cases and Outbreaks, July 16, 2026; Johns Hopkins Measles Tracker, July 22, 2026
- What it shows: 2,260 to 2,295 confirmed cases in 44 jurisdictions; summer travel actively driving spread; MMR vaccination widely available at pharmacies, health departments, and FQHCs
- What it does not prove: That any specific clinic will have supply on any given day; readers should confirm availability before visiting
-
What readers should know: Two documented MMR doses provide approximately 97% protection; unvaccinated people should act before the peak transmission period continues
Who Faces the Greatest Risk?
People at highest risk for measles and who should prioritize vaccination include:
- Children who have not received both recommended MMR doses
- Adults born in 1957 or after who cannot document two MMR doses and have no confirmed measles immunity
- Travelers planning international or domestic travel, particularly to areas with active outbreaks
- People in South Carolina, Utah, Texas, Michigan, and other heavily affected jurisdictions
- Anyone who has been in a known measles exposure setting, where post-exposure vaccination within 72 hours may provide some protection
-
Healthcare workers and school personnel who may have high-contact exposure
Symptoms and Warning Signs to Watch For
If you believe you have been exposed to measles or develop these symptoms, call your clinician before visiting a clinic:
- High fever, sometimes above 104°F
- Cough, runny nose, and red watery eyes
- Small white spots inside the mouth (Koplik's spots) appearing one to two days before the rash
- A red, blotchy rash beginning at the hairline and spreading downward
Measles is contagious from four days before the rash appears through four days after. Calling ahead allows clinics to prepare appropriate isolation measures. Arriving unannounced at an emergency room with measles symptoms can expose other waiting patients.
What You Can Do Now
- Check your immunization records. If you have a MyChart account, your vaccination history may be accessible online through your health system. Many state immunization registries also allow patients to view their records online.
- Check your children's school health records to confirm two documented MMR doses.
- Visit vaccines.gov and enter your ZIP code to find MMR vaccination locations near you, with information on cost and appointment requirements.
- If you are uninsured, call 2-1-1 or visit hrsa.gov to find the nearest federally qualified health center for free or sliding-scale vaccination.
- If you are insured, MMR vaccination is covered at no cost under the Affordable Care Act's preventive care provisions for all ages.
-
If you are traveling this summer, verify your vaccination status before your trip. The CDC recommends that all travelers be current on MMR.
Cost and Access: What Patients Should Know
Under the Affordable Care Act, MMR vaccination is covered at no cost for children and adults through most private insurance plans, including Marketplace plans, when administered at an in-network provider. Medicare Part B covers MMR vaccination for beneficiaries at risk.
For uninsured or underinsured adults, local health department clinics in most jurisdictions offer MMR vaccination at reduced or no cost. FQHCs serve patients on a sliding fee scale; no one is turned away for inability to pay.
Pharmacy-based MMR vaccination without insurance typically costs between $100 and $150 per dose, with cost-reduction options available through GoodRx coupons, which can significantly lower the out-of-pocket price at CVS, Walgreens, and Walmart pharmacies. GoodRx can be searched for the most current reduced pricing at specific pharmacy locations.
Children 18 and under who are uninsured qualify for free MMR vaccination through the Vaccines for Children (VFC) program at any participating provider.
What Happens Next
The CDC updates its measles case count weekly, typically on Thursdays. The next update is expected late July 2026. The Johns Hopkins U.S. Measles Tracker updates more frequently, drawing from state and local data.
The PAHO Regional Verification Commission will meet in November 2026 to formally assess U.S. measles elimination status. That review will evaluate genomic sequencing data alongside case counts and public health response. Vaccination coverage in school districts and communities across the country will be relevant context for that determination.
The Bottom Line
The single most effective action most unvaccinated or under-vaccinated Americans can take in response to the 2026 measles outbreak is to get the MMR vaccine this week. It is available without an appointment at most major pharmacy chains, at county health department clinics, and at federally qualified health centers. For children without insurance, it is free through the VFC program. For insured adults, it is covered at no cost. Two documented doses provide 97% protection against a disease that is currently active in 44 states and may cost the United States its measles-free designation in November. Getting vaccinated takes 15 minutes. Check your records, find a location, and get it done.
