(Adnkronos) - GAITHERSBURG, Md., Aug. 22, 2023 /PRNewswire/ -- Novavax, Inc. (Nasdaq: NVAX), a global company advancing protein-based vaccines with its novel Matrix-M™ adjuvant, today announced that its updated protein-based XBB COVID vaccine candidate induced neutralizing antibody responses to the EG.5.1 and XBB.1.16.6 subvariants in small animal and non-human primate studies. XBB sublineage variants are overwhelmingly responsible for the majority of current COVID cases in the U.S. and European Union.1, 2
"Our data have shown that Novavax's protein-based COVID vaccine induces broadly neutralizing responses against XBB subvariants, including EG.5.1 and XBB.1.16.6," said Filip Dubovsky, President of Research and Development, Novavax. "We have a lot of confidence in our updated COVID vaccine and are working diligently with global regulatory bodies to ensure our protein-based vaccine is available this fall."
Non-clinical data previously showed that Novavax's 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.3 Novavax is in the process of submitting applications for its XBB.1.5 COVID vaccine candidate to regulatory authorities globally.
