Industry Context

The exclusive licensing agreement for Vaxart's oral COVID-19 vaccine candidate positions Dynavax to potentially innovate within the multi-billion-dollar COVID-19 vaccine market by offering an easily administered, novel delivery method. This move aligns with a broader industry trend towards more convenient and accessible vaccine options. The positive Phase 1/2 data for the shingles vaccine candidate (Z-1018), particularly its favorable tolerability profile compared to Shingrix, suggests potential for a differentiated product in a competitive and growing market for adult vaccines. Dynavax's continued market share gains for HEPLISAV-B in the U.S. adult hepatitis B vaccine market reflect ongoing public health vaccination efforts and the product's strong competitive positioning.

Comparison to Industry Standards

• HEPLISAV-B is the first and only adult hepatitis B vaccine approved in the U.S. that enables series completion with only two doses in one month, offering a differentiated dosing schedule compared to other available vaccines.
• The shingles vaccine candidate Z-1018 demonstrated a favorable tolerability profile, including lower solicited local and systemic post-injection reactions, versus Shingrix, a leading competitor.
• Z-1018 also showed robust immune responses with comparable immunogenicity to Shingrix at the dose selected for advancement.
• Vaxart's oral COVID-19 vaccine candidate, now licensed by Dynavax, has a novel mechanism of action and delivery method relative to commercially available COVID-19 vaccines, potentially transforming the market.
• Dynavax's investigational Lyme disease vaccine candidate, adjuvanted with CpG 1018, is being developed with the potential for a differentiated and best-in-class profile, contrasting with current vaccine candidates in clinical development that require three-dose primary series and annual boosters.
