Mexico is in the midst of an escalating measles outbreak response that is expected to intensify significantly in the coming weeks. President Claudia Sheinbaum Pardo has announced an ambitious National Measles Response Strategy aimed at dramatically increasing vaccination coverage across the country, with local governments at all levels mobilizing resources to contain what has become a multi-state public health emergency.
As of mid-February 2026, Mexico has administered over 16 million measles vaccine doses since the beginning of 2025, according to Articles 1, 4, and 5. The vaccination campaign has shown remarkable momentum, with nearly 1.7 million doses administered during the week of February 7-13 alone—almost double the previous week's rate following the government's national announcement. The outbreak has confirmed cases in multiple states, with Hermosillo, Sonora reporting 11 confirmed cases as of February 17 (Articles 2 and 3). President Sheinbaum has identified 11 high-incidence states: Jalisco, Colima, Chiapas, Sinaloa, Durango, Mexico City, and others not fully named in the coverage (Article 4). The government has secured 27 million vaccine doses currently in distribution and has committed to purchasing an additional 15 million doses from the Pan American Health Organization (PAHO) to ensure sufficient supply through 2026 and 2027 (Articles 1, 4, and 5).
**Accelerating Government Response**: The near-doubling of weekly vaccination rates between early and mid-February demonstrates both government capacity and public responsiveness. The establishment of vaccination centers beyond traditional health facilities—including municipal buildings like Hermosillo's Palacio Municipal—signals an all-hands-on-deck approach (Articles 2 and 3). **Multi-Level Government Coordination**: The Third Session of Hermosillo's Municipal Health Council brought together authorities from three levels of government, medical institutions, universities, and civil society organizations (Article 2). This pattern of coordination is likely being replicated across affected states. **Prioritized Demographics**: The campaign explicitly targets children aged 6 months to 12 years as the most vulnerable population, along with individuals aged 13-49 with incomplete vaccination records (Articles 1, 4, and 5). This age stratification suggests health authorities are concerned about immunity gaps in multiple generational cohorts. **Proactive Supply Management**: The purchase of 15 million additional doses before current supplies are exhausted indicates the government is planning for sustained high-volume vaccination over an extended period (Articles 4 and 5).
### Short-Term (2-4 Weeks) Mexico will likely reach its target of 2.5 million weekly vaccinations within the next two to three weeks. The trajectory from previous weeks—jumping from approximately 850,000 to 1.7 million doses—suggests the infrastructure and public awareness are scaling rapidly. Once this target is achieved, the government will maintain this pace for at least 6-8 weeks to reach critical coverage thresholds. Additional measles cases will be confirmed in the currently affected states and potentially in new regions. The incubation period for measles (10-14 days) and the lag in testing and reporting mean that cases from mid-February exposures will appear through early March. However, the case growth rate should begin to decelerate by late March as vaccination coverage increases. ### Medium-Term (1-3 Months) Vaccination centers will proliferate beyond health facilities to schools, community centers, shopping areas, and mobile units, particularly in the 11 high-incidence states identified by President Sheinbaum. The model demonstrated in Hermosillo—where municipal government provided space and coordination support—will be replicated nationwide (Articles 2 and 3). The government will likely launch targeted communication campaigns emphasizing the vulnerability of children and the safety of the vaccine, addressing any vaccine hesitancy that may exist in certain communities. The repeated emphasis by President Sheinbaum on vaccinating children (Article 5) suggests this will be a central messaging priority. By April 2026, Mexico should begin seeing measurable declines in new measles cases as vaccination coverage reaches critical thresholds in the most affected regions. The aggressive response—if the 2.5 million weekly target is sustained—could deliver 30-35 million doses by early May, significantly improving population immunity. ### Potential Challenges Logistical challenges may emerge in rural and remote areas where healthcare infrastructure is limited. While the government asserts there is no vaccine shortage (Articles 1, 4, and 5), distribution efficiency will be tested as the campaign scales. States with lower administrative capacity may struggle to match the vaccination rates of more developed regions. Border regions may experience continued vulnerability due to cross-border movement with the United States and Guatemala, potentially requiring enhanced coordination with international health authorities.
Mexico's measles response represents one of the most ambitious rapid vaccination campaigns in recent Latin American history. The government's commitment of resources, multi-level coordination, and clear communication strategy position the country well to contain this outbreak. However, success depends on sustaining the momentum through March and April 2026, when vaccination fatigue typically sets in. The next 60-90 days will be critical in determining whether Mexico can prevent this outbreak from becoming a sustained epidemic. All indicators suggest the government is treating this as a priority crisis, which bodes well for containment outcomes by mid-2026.
Vaccination rates nearly doubled from one week to the next in mid-February, showing strong scaling capacity and infrastructure. The trajectory suggests the 2.5 million target is achievable with continued momentum.
Measles has a 10-14 day incubation period, and cases from mid-February exposures will continue to appear. However, growth rate should decelerate as vaccination coverage increases.
Hermosillo has already established this model at Palacio Municipal. The government's ambitious 2.5 million weekly target requires distributing vaccination beyond conventional health facilities.
President Sheinbaum's repeated emphasis on vaccinating children and the government's urgent tone suggest a coordinated messaging campaign is being prepared to drive uptake.
If 2.5 million weekly doses are sustained, critical vaccination coverage thresholds should be reached by early-to-mid April 2026, leading to reduced transmission rates.
While the government asserts sufficient vaccine supply, distributing 2.5 million doses weekly across Mexico's diverse geography will stress distribution systems, particularly in underserved areas.
If the outbreak spreads more widely or vaccination uptake exceeds projections, the government may need to secure additional supplies, though current procurement appears adequate for stated goals.
