In response to a concerning increase in measles cases, which have reached over 10,000 confirmed cases since January 2025, the Mexican health authorities are intensifying their vaccination campaign. The Secretary of Health, in collaboration with the Epidemiological Surveillance System for Exanthematous Fever Diseases, has reported a surge in measles cases, necessitating immediate action to safeguard public health. Clara Brugada, the Head of Government in Mexico City, has established 300 vaccination centers and employed 1,500 health workers to enhance outreach across the city.

Initially, vaccination modules were only available during morning hours at strategic points, particularly at heavily trafficked public transport stations; however, the need for greater community involvement led to the advent of nighttime locations. This decision allows those who work during the day to access vaccination services more conveniently, thereby aiming to raise the overall immunization rate within the city and protect against the outbreak, which poses significant health risks.

The city's move to activate nighttime vaccination modules reflects a proactive stance in addressing public health issues and ensuring that the population is adequately protected against measles. By extending vaccination options and engaging a larger segment of the community, health officials hope to reduce transmission rates and avert further escalation of the outbreak. Ensuring widespread access to vaccines will be crucial in managing the current health emergency and restoring public confidence in health services.
