Combo mRNA COVID Flu Vaccine Shows Promise in Moderna Trial

A combined COVID-19 and flu vaccine may be more effective at boosting immunity than two separate shots in some people, according to preliminary results released by Moderna on Monday. The statement comes from Moderna’s ongoing Phase 3 clinical trial, the gold standard test a treatment, including a vaccine, must pass.

The results, although not published or peer-reviewed, suggest that the combination mRNA vaccine works as well or better than comparative vaccines against different strains of both viruses, Moderna said.

Full results of the trial will be published later this year, Moderna added. If federal regulators approve the combination vaccine for use, it could be available to people by the end of 2025.
