Mexico City is intensifying its efforts to combat a recent surge in measles cases, with officials aiming to achieve community immunity by March. More than one million residents have already received the measles vaccine as part of an expansive public health campaign, spearheaded by Mexico City’s Head of Government, Clara Brugada. This push comes as the country grapples with a national outbreak, currently reporting 8,899 confirmed cases and 28 deaths between 2025 and 2026, according to the General Directorate of Epidemiology.
The urgency stems from the potential for rapid transmission of the highly contagious virus, particularly among unvaccinated populations. Brugada emphasized the importance of widespread vaccination to protect vulnerable individuals and prevent further complications from the disease. The city’s strategy focuses on reaching a 95% immunity threshold, a level considered crucial for halting the spread of measles. Achieving community immunity is a key goal for public health officials.
Mass Vaccination Campaign Underway
The vaccination campaign, which began in August 2025, has already inoculated over 1.6 million people in Mexico City as of February 13, 2026. In the past six days alone, more than 40,000 individuals have received the vaccine, with vaccination sites operating both during the day and at night to maximize accessibility. Brugada recently held a virtual meeting with Mexican President Claudia Sheinbaum to coordinate national vaccination efforts and express gratitude for the public’s patience during the rollout. Sheinbaum has also called for calm amidst the outbreak, reinforcing the importance of relying on information from health authorities and prioritizing vaccination, especially for children.
“Remember that the vaccine is the best tool, the most effective for reducing the chain of transmission of measles. And it also avoids serious complications, of course, prevents avoidable deaths,” Brugada stated during a press conference from the Zócalo capitalino.
Areas of Concern and Targeted Efforts
While the overall vaccination rate is encouraging, certain areas of Mexico City have experienced higher concentrations of measles cases. As of February 2026, the boroughs of Gustavo A. Madero (44 cases), Álvaro Obregón (39 cases), Cuauhtémoc (23 cases), and Miguel Hidalgo and Iztapalapa (14 cases each) have reported the most active infections. Notably, 77% of the 217 active cases in Mexico City between 2025 and 2026 involved individuals who had not previously been vaccinated. A tragic case involving a three-month-traditional infant who died on December 30th due to measles has further underscored the severity of the situation.
In response to concerns about potential stigmatization, Brugada has urged media outlets to exercise caution when reporting on case numbers by borough, emphasizing the demand to avoid creating negative perceptions of specific communities. Brugada’s call for responsible reporting aims to prevent discrimination and encourage residents to seek vaccination regardless of their location.
National Response and Continued Vigilance
The Mexican government is reinforcing vaccination efforts nationwide, with a particular focus on immunizing children. President Sheinbaum has emphasized that the majority of the population is already vaccinated, providing a crucial layer of protection. Though, authorities are urging those who are not vaccinated to do so promptly, as they are at higher risk of severe illness. The ongoing campaign represents a significant logistical undertaking, with 1,500 vaccination personnel deployed across 500 brigades throughout the capital city, as reported by the Mexico City government.
Looking ahead, health officials will continue to monitor the spread of measles and assess the effectiveness of the vaccination campaign. The success of the initiative will depend on maintaining high vaccination rates and ensuring equitable access to the vaccine for all residents. Continued public awareness and adherence to health guidelines will be essential in preventing further outbreaks and protecting the health of the community.
