Summer travel and measles: What Michigan families need to know
Print
EmailAs you make your summer travel plans, be sure to check your immunization status before heading out.
On March 11, Michigan reported its first case of measles in 2026. As of July 1, that number has risen to 14 cases. Measles is a highly contagious infection that can lead to serious health complications, including long-term health problems and, in some cases death.
Measles cases have also been increasing across the country. In 2025, the United States reported 2,285 cases, the highest number of confirmed measles cases since the disease was declared eliminated in 2000. As of July 1, 2026, there have already been 2,122 reported cases nationwide.
Declining vaccination rates are contributing to the increased spread of measles. A 95% vaccination rate within a community is needed to provide optimal protection. In Michigan, the current measles, mumps, and rubella (MMR) vaccination rate is 91.6%, which is below the level needed to effectively prevent outbreaks.
Vaccination remains the best way to prevent measles and other infectious diseases. The MMR vaccine is typically given as a two-dose series. Administration of the first dose occurs between 12-15 months of age, and the second dose is administered between 4-5 years old. In certain cases, such as potential exposure to measles or travel to areas where measles is spreading, infants as young as 6 months may receive the vaccine. If you have questions about your child’s eligibility, talk to your healthcare provider about vaccination options.
The MMR vaccine is highly effective at preventing measles infection. One dose is approximately 93% effective, while two doses are about 97% effective. In most cases, two doses provide lifelong protection against measles. As cases around the country and in Michigan continue to rise, vaccination remains to best way to prevent a measles infection.
