Mexico Flags Patria Vaccine for Possible Yellow Fever Use as Cofepris Review Continues

Mexico is pursuing mRNA technology transfer from Pfizer and Moderna to build domestic capacity for future vaccines.

Overview

  • Health Secretary David Kershenobich said the domestically developed Patria shot could be adapted to address diseases such as yellow fever.
  • The vaccine is currently undergoing required testing with Cofepris as it seeks sanitary registration for COVID-19 use.
  • Officials highlighted that Patria uses a viral‑vector platform distinct from mRNA vaccines, which they view as offering repurposing potential.
  • Mexico continues to administer Moderna and Pfizer RNA vaccines for COVID-19 while training personnel and seeking RNA technology transfer.
  • For the current season, authorities reported a little over 10 million COVID-19 doses for high‑risk groups and 40 million influenza doses in stock.
