Do You Need to Check Your Family’s Measles Shots Before Summer Travel?

If your family is traveling this summer, checking measles vaccine records now can prevent last-minute stress. That is especially true if anyone in your household will travel internationally, has an unclear vaccine history, or may be due for a routine MMR shot.

CDC’s national measles page, updated June 18, 2026, reported 2,104 confirmed U.S. cases this year, with 93% linked to outbreaks. CDC also notes that measles often spreads during heavy travel periods such as spring break, summer, and holidays. Its measles travel guidance was updated April 29, 2026.

Who should check records now

Three groups deserve special attention before summer trips: children who may be due for routine shots, infants who will travel internationally, and teens or adults who are not sure whether they ever received measles vaccine.

For most children, the usual protection comes through the MMR vaccine series. The American Academy of Pediatrics says the routine schedule is one dose at 12 to 15 months and a second dose at 4 to 6 years. If your child already had one dose and an international trip is coming up, check records early and ask the child’s clinician whether the second dose should be given before travel.

Infants are a separate case. CDC and the AAP say babies ages 6 through 11 months should get an early MMR dose before international travel, ideally at least two weeks before departure. That early dose does not replace the regular childhood series, so those children still need another dose at 12 to 15 months and a final dose at 4 to 6 years. Infants younger than 6 months are too young for MMR, so families with very young babies should discuss travel risk and exposure precautions with their pediatrician.

Teens and adults should check too, especially if they do not know their vaccine history. CDC says people with no evidence of immunity should be vaccinated before international travel. Acceptable evidence can include written vaccine records, lab evidence of immunity, lab confirmation of past measles, or birth before 1957. If your records are unclear, a doctor’s office, pharmacy, clinic, or local health department may be able to help you sort out what documentation you have and what to do next.

Routine advice is not the same as travel or outbreak advice

The routine U.S. childhood schedule has not changed. What changes during travel season or during outbreaks is the urgency of checking whether you are protected.

CDC’s current measles travel page is mainly about international travel. It says people who are not already vaccinated or who do not know their status should try to get vaccinated at least two weeks before departure. If a trip is less than two weeks away, CDC still says getting a dose can help.

For children older than 12 months and for teens or adults with no evidence of immunity, CDC says to get a first dose right away and a second dose 28 days later. If someone already received one MMR dose, CDC advises getting the second dose before an international trip.

For families staying within the United States, the practical step is still to make sure routine MMR vaccination is up to date, especially if you are heading to an area with active spread, camps, or other crowded settings. The special early-dose guidance for infants and the two-weeks-before-you-go timing come from CDC’s international travel recommendations.

Why families are hearing more about measles this summer

Part of the reason is simple: there is a lot of measles activity right now. CDC says national kindergarten MMR coverage fell from 95.2% in the 2019 to 2020 school year to 92.5% in 2024 to 2025, leaving about 286,000 kindergartners at risk. CDC also notes that measles is not a seasonal virus, but it often spreads during high-travel periods and in close-quarter settings.

A recent CDC report in MMWR adds context about how serious measles can become. The report examined the first three months of the 2025 West Texas outbreak and found that 60 of 325 confirmed cases, or 18.5%, were hospitalized. Among 54 hospitalized patients whose records were available for review, all were unvaccinated or had unknown vaccination status, about 70% had pneumonia, many needed oxygen, and one patient died.

That report has important limits. It covered one outbreak area, likely missed some mild cases, and CDC said that may have made the hospitalization rate look higher than it would in a more complete count. It also relied on incomplete medical records and an opt-in state vaccine registry, so some vaccination histories may not have been verifiable. Even so, it is a useful reminder that measles is not always a mild illness.

What to do after exposure or if symptoms start

If you think you or your child were exposed to measles, call a healthcare provider right away. CDC says to call immediately if you think there has been an exposure and to mention recent travel and vaccination history.

If symptoms begin, especially fever with cough, runny nose, red watery eyes, or a rash, do not just walk into a waiting room without warning. Call ahead so a clinic or hospital can tell you how to come in safely and reduce the chance of exposing other patients. CDC says people with measles can spread the virus from four days before the rash appears through four days after it starts.

After international travel, CDC says to watch your health for three weeks after you return. Babies and young children, pregnant people, adults older than 20, and people with weakened immune systems are at higher risk of complications. If someone seems seriously ill, seek urgent medical care and call ahead before arrival.

What readers can do this week

Find your family’s vaccine records now, before travel gets close.
Check whether children are up to date on the routine MMR schedule.
If an infant age 6 through 11 months will travel internationally, ask the child’s clinician promptly about the early travel dose.
If a baby younger than 6 months will travel, ask the pediatrician about risk reduction because MMR is not recommended at that age.
If a teen or adult is unsure about measles immunity, contact a clinician, pharmacy, or local health department to review records and next steps.
If fever and rash develop after travel or a known exposure, call ahead for medical advice the same day.

The bottom line is simple: summer plans are easier when vaccine questions are settled early. Checking MMR records now can help your family avoid delays, confusion, and preventable exposure later.
