• Novavax has developed a protein-based monovalent XBB.1.5 COVID vaccine candidate and is manufacturing at commercial scale with the intent to be in market during the fall vaccination campaign
• Novavax shared data demonstrating that its XBB.1.5 COVID vaccine candidate induces functional immune responses to XBB subvariants including XBB.1.5, XBB.1.16 and XBB.2.3
• If authorized, Novavax's protein-based vaccine candidate would be the only non-mRNA XBB.1.5 vaccine available in the U.S.
• Novavax intends to supply vaccine globally, consistent with FDA, WHO and EMA recommendations

"Novavax expects to be ready for the commercial delivery of a protein-based monovalent XBB COVID vaccine this fall in line with today's VRBPAC recommendation," said John C. Jacobs, President and Chief Executive Officer, Novavax. "In partnership with regulators and public health authorities, Novavax has been developing and manufacturing this vaccine candidate, and now that we are nearing harmonization on guidance from the FDA, the World Health Organization and European Medicines Agency, we believe we are in a better position to offer an alternative vaccine choice for individuals worldwide."

Novavax presented data at the VRBPAC meeting that supports the recommendation to vaccinate this fall with a monovalent XBB strain. Novavax data showed that its XBB.1.5 COVID vaccine candidate induced functional immune responses for XBB.1.5, XBB.1.16 and XBB.2.3 variants, indicating a broad response that could potentially be applicable for forward-drift variants.

Novavax will seek updated FDA labeling for its XBB COVID vaccine candidate with the goal of it being available and accessible on par with other COVID vaccines.
