April is early enough to fix a missing vaccination record before summer travel becomes urgent. It is also late enough in the year that California’s 2026 measles activity was no longer an isolated January event. The safest planning step is to review documented MMR doses first, then ask a healthcare provider what the traveler needs based on age, destination, prior vaccination, pregnancy or immune considerations, and any known exposure.
Quick Answer
CDPH reported 35 confirmed measles cases in California as of April 6, 2026; 33 of those 35 cases were in people who were unvaccinated or whose vaccination status was unknown. Later 2026 state data recorded 12 cases with April rash onset in Orange, Riverside, Sacramento, and San Francisco counties. Before summer travel, check documented MMR doses rather than relying on memory. California’s Digital Vaccine Record can show vaccinations reported to the California Immunization Registry, although older doses may be missing if they were never reported. CDPH says it takes about two to three weeks to get the most protection against measles after vaccination. For international travel, CDPH recommends an early MMR dose for infants 6–11 months and says people 12 months and older should be up to date with two doses; the timing and whether an early dose applies should be confirmed with a healthcare provider. If a traveler may have been exposed to measles or develops fever with rash, cough, runny nose, or red eyes, contact a healthcare provider or local public health department for guidance before going to a pharmacy, clinic, or other public setting.
What California Was Reporting in April
CDPH’s April 6 snapshot listed 35 confirmed measles cases reported in California during 2026. At that point, 33 cases, or 94%, were in people who were unvaccinated or whose vaccination status was unknown.
As the year progressed and surveillance data were updated, CDPH’s 2026 table recorded 12 cases with April rash onset across Orange, Riverside, Sacramento, and San Francisco counties. The state labels these case data provisional and subject to change.
- 35 cases by April 6
- California entered April with measles activity already documented across multiple counties in 2026.
- 94% unvaccinated or unknown
- At the April 6 snapshot, 33 of 35 reported cases fell into this vaccination-status group.
- April-onset cases followed
- Later state data attributed 12 cases to April rash onset in four California counties.
- Travel remained relevant
- CDPH continued to emphasize immunization review for people planning domestic or international travel.
Case Counts Are a Reason to Review Records, Not to Guess Immunity
Start With the Vaccine Record, Not With Memory
California’s Digital Vaccine Record is an official electronic immunization record from the California Immunization Registry, or CAIR. It can include vaccination dates and vaccines reported by healthcare providers and pharmacies.
CDPH also cautions that not every historical vaccination may appear in CAIR. If a record is missing or incomplete, contact the healthcare provider or pharmacy that administered the vaccine and use the My DVR Assistant when appropriate.
What does your travel record situation look like?
01. Can I find the traveler’s documented MMR doses in the California Digital Vaccine Record, provider portal, pharmacy record, or paper record?
02. Are the vaccination dates complete enough to show how many MMR doses were actually received?
03. If a dose is missing from CAIR, can the administering provider or pharmacy verify it?
04. Is the traveler an infant, child, adolescent, adult, pregnant person, or someone with immune-system considerations?
05. Is the trip international or to a domestic area with an active measles outbreak?
06. Is there enough time before departure to ask a healthcare provider about any needed vaccination?
A Missing Digital Record Does Not Prove a Vaccine Was Never Given
Review MMR Status Before Summer Travel Gets Close
CDPH says the body takes about two to three weeks to get the most protection against measles after vaccination. That makes April a practical time to review records for summer trips instead of waiting until the departure week.
For international travel, CDPH recommends one MMR dose for babies 6–11 months and says everyone 12 months and older should be up to date with two doses. CDPH also advises people traveling to domestic measles outbreak areas to consult a healthcare provider about following international-travel immunization recommendations.
- International trip
- Review the traveler’s age and MMR record with a healthcare provider early enough to address the travel recommendation.
- Domestic outbreak area
- Ask a healthcare provider whether the international-travel MMR recommendations should be followed for that destination.
- Infant 6–11 months
- International travel can involve an early MMR dose; confirm the timing and later routine doses with the child’s healthcare provider.
- 12 months and older
- CDPH says travelers should be up to date with two doses before international travel.
Travel Timing Does Not Create a Do-It-Yourself Vaccine Schedule
Where Californians Can Check Records and Find Vaccination
California’s Digital Vaccine Record portal can provide a copy of vaccinations reported to CAIR. My Turn can help people locate vaccination sites, appointments, and walk-in options.
Pharmacies may also offer routine vaccination, but inventory, age policies, appointment rules, insurance participation, and vaccine availability can differ by location. Call ahead instead of assuming a specific pharmacy has MMR vaccine available for the traveler.
- Digital Vaccine Record
- Use California’s DVR to review immunizations reported to the state registry.
- Healthcare provider
- Ask the provider to review age, prior doses, health history, travel destination, and timing.
- My Turn
- Use California’s vaccine site to look for participating vaccination locations and appointment options.
- Local pharmacy
- Call to confirm MMR availability, age policy, appointment requirements, insurance, and record reporting before visiting.
Finding a Vaccine Location and Deciding What the Traveler Needs Are Different Steps
Exposure or Symptoms Need a Different Next Step
A routine pre-travel record check is different from a possible measles exposure or illness. CDPH has advised people with possible measles to contact healthcare providers before entering a healthcare setting so staff can plan testing and reduce exposure to others.
Possible symptoms can include fever and rash along with cough, runny nose, or red eyes. A pharmacy is not the place to arrive unannounced for measles evaluation.
- Known exposure
- Contact a healthcare provider or local public health department promptly for exposure-specific guidance.
- Fever plus rash
- Call a healthcare provider before arriving at a clinic, pharmacy, urgent care, or other public healthcare location.
- Routine record question
- Use DVR, the healthcare provider, or prior pharmacy records to verify documented vaccination.
- Routine vaccine access
- Call ahead to confirm location, appointment, age policy, inventory, and insurance details.

A Pre-Travel Measles Record Checklist
Use this list several weeks before a summer trip.
01. Open the California Digital Vaccine Record or another reliable immunization record and locate documented MMR doses.
02. If the record is incomplete, contact prior healthcare providers or pharmacies that may have administered the missing dose.
03. Tell the healthcare provider whether the trip is international or to a domestic area with active measles transmission.
04. Ask early enough to account for the two-to-three-week period CDPH says is needed to get the most protection after vaccination.
05. For pharmacy vaccination, call ahead to confirm MMR availability, age policy, appointment requirements, and insurance participation.
06. If there is a known exposure or possible measles illness, contact a healthcare provider or public health department before going to a pharmacy or clinic.
Frequently Asked Questions
How many measles cases had California reported by early April 2026?
CDPH’s April 6 snapshot reported 35 confirmed measles cases in California during 2026. The data were provisional and were updated as the year continued.
Where can I check my California vaccination record?
California’s Digital Vaccine Record portal provides an official electronic immunization record using vaccinations reported to the California Immunization Registry.
What if my MMR dose is missing from the Digital Vaccine Record?
A missing entry does not prove the dose was never given. Contact the healthcare provider or pharmacy that administered it and use California’s record-correction process when appropriate.
How early should I review measles vaccination before summer travel?
Start several weeks before departure. CDPH says it takes about two to three weeks to get the most protection against measles after vaccination, and some travelers may need more than one step.
Should I go to a pharmacy if I think I was exposed to measles?
For a known exposure or possible symptoms, contact a healthcare provider or local public health department first. Do not arrive unannounced at a pharmacy or healthcare setting for measles evaluation.
