COVID-flu combo vaccine from Novavax sparks immune response to both viruses in animals

As Novavax prepares to file for FDA emergency use authorization of its COVID-19 shot, the vaccine developer is already looking ahead to the possibility of combining coronavirus and flu protection.

Novavax combined its investigational flu vaccine, NanoFlu, with the COVID-19 vaccine shot, NVX-CoV2373, and tested it in ferrets and hamsters. The shot produced antibodies against both viruses at levels comparable to what was seen with either component vaccine alone, the company reported on the journal preprint site bioRxiv.
