Nearly 100 health workers fanned out from Puerto Vallarta this week. They headed into beach towns and mountain communities with one message: check your measles shots. The Costa Norte and Sierra Occidental effort is part of a larger push as Jalisco confronts rising cases statewide. The campaign isn’t only about children. Adults who aren’t sure they were vaccinated are being urged to verify their records and catch up. For expats, that can mean locating old documentation. It can also mean asking a clinic to review your status. Then take a dose at your location.
A regional push from Puerto Vallarta outward
On Monday, January 26, health teams based in Puerto Vallarta moved beyond the city limits and into smaller communities. Nearly 100 brigadistas from Jalisco’s Octava Región Sanitaria deployed across the region. It covers Puerto Vallarta, Cabo Corrientes, Tomatlán, Mascota, Talpa de Allende, and San Sebastián del Oeste. The mission is to bring measles vaccination closer. It targets people who missed doses, never got vaccinated, or lack clear records. Brigades are working in parallel across many localities. That helps remote ranches and mountain towns. Some teams vaccinate house-to-house. Others set up temporary posts in community spaces. Residents can also visit their local health center without waiting for a brigade to arrive. Health officials are urging residents to check their immunization cards. They also want families to complete any missing shots at the nearest clinic. If you are an expat, the same advice applies. If you travel often, confirm your status now. If you have kids in school, check their cards too. A quick check today can prevent a stressful scramble later.
Why officials are moving fast
Measles is one of the most contagious viruses public health teams deal with. It exploits vaccination gaps quickly. It can spread through households, schools, and workplaces before people realize they are carrying it. Severe cases can lead to serious complications. Young children and unprotected adults face the highest risks. Jalisco’s broader response reflects that urgency. In late January, the state health secretary reported 1,275 confirmed cases in 38 municipalities. He said 324 cases were active, mostly in the Guadalajara metro area. Officials say vaccination remains the fastest way to stop the spread. To cut transmission, the state presented an intensive plan. It relies on more than 1,000 brigades and hundreds of fixed vaccination sites. Mobile modules are also being set up in high-traffic public spaces. High mobility between tourist areas, highways, and rural towns raises the stakes. Local health leaders say the coastal-and-sierra region has seen dozens of cases since 2025. Vaccination rounds have expanded in neighborhoods with new detections.
What to check in your vaccine record
Mexico’s routine schedule uses the triple-viral measles vaccine, known locally as SRP. The first dose is at 12 months, and the second is at 18 months. Timing matters. Some children may need a later catch-up dose, depending on when they started. The campaign also targets adults under 50. It focuses on incomplete schedules or missing records. If you are unsure, start with what you can find. Bring any vaccine card, school record, or clinic note. Then take it to a health center and ask the staff to review your status. Vaccines are being offered through state clinics and public health institutions. Mobile modules are also rotating through busy areas. If you were vaccinated outside Mexico and cannot document it, ask a clinician for their recommendation. Some clinics will advise a dose when proof is missing. If you are pregnant or immunocompromised, ask for guidance before vaccination. The fastest win, for locals and expats alike, is to close any gaps now.
