Mexico Launches Ambitious Winter Vaccination Drive Targeting 50.5 Million

mexico City, Mexico – October 16, 2025 – Mexico has commenced its National Winter Vaccination Campaign, a sweeping public health initiative poised to deliver over 50.5 million doses of vaccines against seasonal influenza, COVID-19, and pneumococcal disease. The program, running from October 2025 to April 2026, prioritizes children under five, senior citizens, expectant mothers, healthcare workers, and individuals managing underlying health conditions.

A Multi-pronged Approach to Winter Health

The nationwide campaign, coordinated by the National Center for Child and Adolescent Health (CENSIA), is designed to alleviate pressure on healthcare systems and prevent severe complications during the colder months. Officials aim for a minimum coverage rate of 95% across the country, utilizing digital monitoring to track progress and ensure widespread access to vaccines.

Vaccine Allocation and Distribution

Secretary of Health David Kershenobich Stalnikowitz announced the allocation of 35.4 million influenza doses, 10.9 million COVID-19 doses, and 4.2 million pneumococcal vaccines. All branches of the National Health System – including IMSS, ISSSTE, PEMEX, SEDENA, SEMAR, and IMSS-Bienestar – will participate in the rollout, operating under the technical guidance of CENSIA.

State Vaccination Councils (COEVAS) are tasked wiht achieving 70% coverage by December 31st and full national coverage by April 2026, with a specific focus on reaching vulnerable communities in both rural and urban settings. The campaign is designed to eliminate missed vaccination opportunities, ensuring every eligible individual receives the appropriate immunizations during healthcare visits.

Updated Formulations and Vaccination Strategies

The seasonal influenza vaccine administered this year is a quadrivalent, inactivated formulation, updated in accordance with the World Health Organization’s (WHO) recommendations for the 2025-2026 Northern Hemisphere season. This updated vaccine provides broader protection against circulating Type A and B influenza viruses, including recent variants prevalent in north America and Europe. It will be given intramuscularly, with a standard dose of 0.5 mL.

Did You Know? The WHO updates influenza vaccine strains annually to match circulating viruses, striving for optimal protection each flu season.

Combating COVID-19 with New Variants in Mind

For the second consecutive year, COVID-19 vaccination is integrated into Mexico’s winter health strategy. This year, the campaign will utilize Spikevax LP.8.1 (Moderna) and Comirnaty LP.8.1 (Pfizer/BioNTech) vaccines, both monovalent and formulated to target the LP.8.1 variant currently dominating in both America and Europe.

A single dose will be administered at least six months after the last booster, with dosage varying by age (0.25 mL for children, 0.3-0.5 mL for adults). Priority groups include individuals over 60, pregnant women, healthcare personnel, and those with chronic illnesses. National genomic surveillance, in collaboration with GISAID and Nextstrain, continues to monitor emerging variants, reinforcing the need for regular booster shots.

Expanding Pneumococcal Protection

Mexico is introducing a 20-valent pneumococcal vaccine as part of the 2025-2026 campaign, replacing the previous 13-valent vaccine. This new vaccine expands protection against strains of Streptococcus pneumoniae, a leading cause of pneumonia, meningitis, and septicemia, particularly affecting young children and the elderly.

The vaccine will be offered in a single 0.5 mL intramuscular dose to older adults, immunocompromised individuals, and those with underlying chronic conditions. studies by the CDC and the European Medicines Agency (EMA) demonstrate over 90% efficacy against invasive strains and a strong safety profile.

Simultaneous Vaccination and Digital Tracking

Technical guidelines authorize simultaneous management of all three vaccines, maintaining a 2.5 to 5 cm distance between injection sites for optimal effectiveness. Federal entities will deploy mobile teams, establish semi-fixed locations, and conduct sessions in hospitals, schools, and community centers to ensure widespread coverage. Progress will be tracked thru the SISCENSIA platform,enabling real-time monitoring and openness in vaccine delivery.

Vaccine Type	Doses Allocated	Target Groups
Influenza	35.4 Million	Children (6 months – 59 months),Seniors,Pregnant Women,Individuals with Chronic Conditions
COVID-19	10.9 Million	Seniors, Pregnant Women, Healthcare Workers, Individuals with Chronic Conditions
Pneumococcus	4.2 Million	Seniors, Immunocompromised Individuals, Individuals with Chronic Conditions
