Novavax (NVAX) Surges 20.1%: Is This an Indication of Further Gains?

Novavax stock jumped 20.1% following renewed investor interest in vaccine stocks, triggered by pneumonia-related concerns in Russia and positive results from Vaxcyte's pneumococcal vaccine. The company benefits from COVID-19 vaccine approvals and a Sanofi partnership. However, Novavax faces declining revenues and continued quarterly losses, though earnings estimate revisions have improved significantly.
