Overview
- Following a Pan American Health Organization alert on February 4, federal authorities activated mass operations with more than 23.5 million free doses available nationwide.
- Mexico City launched a large campaign with 500 brigades, 300 health centers, 21 late‑night sites open to 23:00, about 100 modules in transit systems, and an overnight operation at the Central de Abasto.
- CDMX has confirmed 166 cases since 2025, including 122 in 2026, with roughly 81% of infections in people without prior vaccination and many cases in adults aged 20 to 45.
- The State of Mexico is running an intensive campaign from February 7 to 15 with 450 vaccination points across its 125 municipalities and has issued school screening and masking guidance.
- Experts link the surge to multi‑year declines in routine coverage, and current protocols include a 'dose zero' for infants 6–11 months in high‑transmission zones alongside the standard schedule.
