Shares of Novavax Inc (NASDAQ:NVAX) are trading higher Tuesday. The stock is up over 30% over the trailing month as traders weigh updated autumn vaccine authorizations against the company’s broader strategic pivot toward licensing and cost-structure optimization.

FDA Clearance For Updated 2026–2027 Nuvaxovid Formula

Providing fundamental support heading into September, Novavax secured U.S. FDA emergency use authorization in late August for its updated protein-based 2026–2027 COVID-19 vaccine (Nuvaxovid).

The approval positions Novavax as the primary non-mRNA alternative for the fall vaccination season alongside mRNA offerings from Pfizer/BioNTech and Moderna. Investors are monitoring early pharmacy shipments as Novavax targets commercial delivery through established retail distribution networks across North America and Europe.

Q2 Guidance Upgrade And Strategic Pivot

Support for the stock is further reinforced by Novavax’s second-quarter financial update delivered in early August, where management raised its full-year revenue guidance following a top-line earnings beat. CEO John C. Jacobs highlighted the structural shift during the call:

"Our Q2 performance demonstrates the execution of our corporate transformation. Through our strategic partnership with Sanofi, we have extended our runway, reduced our operating expense profile, and positioned Novavax to capture recurring value from our Matrix-M platform while maintaining lean commercial operations for the upcoming vaccination season."

The combination therapy significantly improved recurrence-free survival and distant metastasis-free survival in patients with high-risk stage III/IV melanoma post-resection.
