"Both our combination and stand-alone flu vaccine candidates induced robust immune responses and were well tolerated," said Ruxandra Draghia-Akli, MD, PhD, Executive Vice President and Head of Research and Development, Novavax. "This data set adds to findings from our Phase 2 trial and will help inform discussions with potential partners."
Both stand-alone flu and CIC vaccine candidates induced robust immune responses to the vaccine strains (2.4-5.7-fold over baseline). Both vaccine candidates were well tolerated and saw reactogenicity comparable to authorized comparators. Nearly all (>
This descriptive trial was designed to evaluate the safety and immunogenicity of the CIC and stand-alone flu vaccine candidates compared to Nuvaxovid and Fluzone HD in approximately 2,000 adults aged 65 and older. This trial was not adequately powered to demonstrate statistical significance. These results build on previous Phase 2 data.
