H3N2 Influenza Vaccine Available in Mexico, Officials Say

Quintana Roo, Mexico — Following an alert issued by the World Health Organization (WHO) regarding the circulation of influenza AH3N2 subclade K, known in the media as “Super Flu,” Health Secretary David Kershenobich stated that Mexico has sufficient vaccine and treatment to address this variant, which has currently been detected in Europe and the United States.

The federal official reported that only one case has been recorded in the country, corresponding to an 80-year-old patient who received outpatient treatment and progressed favorably without major complications. Therefore, he emphasized that it is a preventable disease through vaccination, which significantly reduces the risk of severe cases and hospitalizations.

Mexican Vaccine Available and Sufficient

David Kershenobich highlighted that the vaccine administered in Mexico, Mexinvac, is 100 percent produced in the country and has been used since the 2024 and 2025 seasons, with sufficient coverage to protect the at-risk population.

“The most important thing is to remember that prevention is the best strategy, beyond focusing solely on treating the disease,” emphasized the head of the Health Secretariat.

The secretary reiterated that permanent epidemiological surveillance is maintained and that, so far, the number of influenza cases in Mexico is similar to that recorded in 2024, a year in which the disease was controlled thanks to vaccination.

Currently, the country is at approximately 50 percent progress in vaccination coverage, so he called on the population to go to health centers to complete their vaccination schedule.

The Secretary of Health of Mexico provided information about this vaccine during the morning conference with President Claudia Sheinbaum.

Priority Groups for Winter Vaccination

The Health Secretariat reminded that the influenza vaccine is primarily aimed at:

• Girls and boys from 6 months to 5 years old
• Adults over 60 years old
• People with chronic diseases such as diabetes, hypertension, obesity, asthma, or kidney disease
• People with compromised immune systems

Health authorities urged the population of Quintana Roo and the rest of the country to go to vaccination centers, medical units, and health centers, as well as to stay informed only through official channels, to avoid misinformation about influenza and the so-called “Super Flu.”
