As of January 2023, the Omicron XBB.1.5 and BQ.1.1 subvariants make up most U.S. We don’t have much information about how well the Novavax COVID-19 vaccine works against newer, prevalent subvariants. Even so, the vaccines have been proven to be a valuable tool in preventing serious illness and death from COVID-19. However, as SARS-CoV-2 continues to produce new variants, COVID-19 vaccine effectiveness seems to be a moving target. It was also 100% effective against moderate to severe disease. During this time, the vaccine was about 90% effective against symptomatic COVID-19. The Novavax vaccine clinical trials initially captured information from late January through April 2021.
