Novavax, Inc. (Nasdaq: NVAX), a global leader in protein-based vaccines, has attained a significant milestone as its updated COVID-19 vaccine, Nuvaxovid™ XBB.1.5 dispersion for injection, received Emergency Use Authorization (EUA) from the Taiwan Food and Drug Administration. This approval marks a pivotal step forward in combating the ongoing pandemic and extends the preventive measure to individuals aged 12 and older.

The Authorization

The authorization follows rigorous evaluations of non-clinical data, demonstrating that Novavax's updated vaccine induces robust immune responses against several variants, including XBB.1.5, XBB.1.16, and XBB.2.3. Notably, the vaccine exhibits compelling neutralizing antibody responses against subvariants BA.2.86, EG.5.1, FL.1.5.1, and XBB.1.16.6, along with eliciting CD4+ polyfunctional cellular (T-cell) responses against EG.5.1 and XBB.1.16.6.

"Receiving Emergency Use Authorization in Taiwan underscores the efficacy of our protein-based non-mRNA vaccine against diverse COVID-19 variants," affirmed John C. Jacobs, President and CEO of Novavax. "The authorization reflects our commitment to supporting global vaccination efforts."

Despite this achievement, concerns surrounding potential revenue risks have prompted a downgrade in the company's stock rating. MoffettNathanson, in a recent report, downgraded Novavax's shares from Neutral to Sell, citing an overvaluation concern. Analysts raised apprehensions about the sustainability of revenue streams amid steep stock price hikes.

"In light of the limited financial disclosures by the company, investors may not fully comprehend the formidable revenue challenges facing Novavax in fiscal year 2024," noted analysts at MoffettNathanson.

The decline in stock recommendation primarily stems from concerns about revenue sources, with recent growth primarily driven by content distribution payments linked to a new significant client and substantial price hikes for subscription-based video-on-demand (SVOD) services. However, reports from Antenna revealed a slowdown in the growth rate of premium SVOD subscriptions in the U.S., signaling potential market constraints.

It is important to note that the trade name Nuvaxovid™ has not yet been approved by the U.S. Food and Drug Administration (FDA). The Novavax COVID-19 Vaccine, Adjuvanted (2023-2024 Formula) has not been licensed by the FDA but has been authorized for emergency use to prevent COVID-19 in individuals aged 12 and older.

While Novavax's updated COVID-19 vaccine garners increased global acceptance, concerns about revenue sustainability continue to impact market sentiment, urging investors to reevaluate the long-term financial outlook for the company.
