Dynavax Technolo Stock Price, News & Analysis
Company Description
Dynavax Technologies Corporation (Nasdaq: DVAX) is a commercial-stage biopharmaceutical company focused on developing and commercializing vaccines to help protect against infectious diseases. The company is classified in pharmaceutical preparation manufacturing within the broader manufacturing sector and is a publicly traded vaccines company. According to company disclosures, Dynavax has built its business around vaccines that incorporate its proprietary CpG 1018® adjuvant, which is designed to enhance immune responses.
Dynavax operates as a vaccines-focused biopharmaceutical business. Its activities span the discovery, development and commercialization of novel vaccines. The company’s revenue base includes sales of its adult hepatitis B vaccine HEPLISAV-B® [Hepatitis B Vaccine (Recombinant), Adjuvanted] and its CpG 1018® adjuvant. Polygon data and company statements indicate that Dynavax generates a substantial portion of its revenue from HEPLISAV-B and CpG 1018, reflecting a model centered on commercial vaccine products and adjuvant supply.
Commercial Products
Dynavax reports two commercial products. HEPLISAV-B is an adult hepatitis B vaccine that combines hepatitis B surface antigen with Dynavax’s CpG 1018 adjuvant, a toll-like receptor 9 (TLR9) agonist, to enhance the immune response. HEPLISAV-B is approved in the United States, the European Union and the United Kingdom for the prevention of infection caused by all known subtypes of hepatitis B virus in adults 18 years of age and older. In the U.S., it is described as the first and only adult hepatitis B vaccine that enables series completion with two doses in one month. Company communications highlight that HEPLISAV-B is usually administered in the arm muscle in two doses given one month apart by a healthcare provider.
The company’s second commercial product is CpG 1018 adjuvant. CpG 1018 is used in HEPLISAV-B and has also been used in multiple adjuvanted COVID-19 vaccines. Dynavax describes CpG 1018 as part of its Toll-like Receptor Immune Modulation Platform and notes that it has demonstrated the ability to enhance immune responses with a favorable tolerability profile across clinical trials and real-world commercial use. This positions CpG 1018 as a core technology that supports both Dynavax’s own vaccines and partnered or external vaccine programs.
Vaccine Pipeline and Development Programs
Beyond its marketed products, Dynavax is advancing a pipeline of investigational vaccines and adjuvant-based programs. These programs are designed to leverage CpG 1018 to improve immunogenicity and tolerability profiles in several infectious disease areas.
The company is developing Z-1018, an investigational non-live, recombinant subunit vaccine candidate for the prevention of shingles (herpes zoster) in adults aged 50 years and older. Z-1018 combines a glycoprotein E antigen with Dynavax’s CpG 1018 adjuvant and alum. Dynavax has reported positive topline data from Part 1 of a Phase 1/2 clinical trial comparing Z-1018 head-to-head with Shingrix® in adults aged 50 to 69 years. According to company press releases and an associated Form 8-K, Z-1018 demonstrated robust antibody and CD4+ T-cell responses comparable to Shingrix, along with a favorable tolerability profile characterized by lower rates of certain post-injection reactions. Based on these results, Dynavax selected a specific dose and regimen for advancement into Part 2 of the Phase 1/2 trial in adults aged 70 years and older.
Dynavax is also collaborating with the U.S. Department of Defense on a plague (rF1V) vaccine candidate adjuvanted with CpG 1018. Company disclosures state that this program is fully funded by the Department of Defense and has moved into Phase 2 clinical evaluation, supported by agreements that provide funding for clinical and manufacturing activities and additional non-human primate studies.
In its pandemic influenza adjuvant program, Dynavax is evaluating CpG 1018 in an adjuvanted H5N1 influenza vaccine as a proof-of-concept for potential use with pandemic influenza vaccines. The company has completed Part 1 of a randomized, active-controlled Phase 1/2 study assessing safety and immunogenicity in adult participants and plans to use those data to select optimal CpG 1018 formulations for further evaluation in Part 2.
The company is also developing an investigational Lyme disease vaccine candidate, described as a multivalent protein subunit vaccine adjuvanted with CpG 1018. Dynavax notes that there are currently no approved human vaccines for Lyme disease and that existing candidates in clinical development require multi-dose primary series and boosters. Based on its adjuvant experience, Dynavax believes its Lyme disease candidate has the potential for a differentiated vaccine profile and reports that the program has progressed into Investigational New Drug (IND)-enabling studies.
Strategic Collaborations and Licensing
Dynavax engages in collaborations that extend its adjuvant and vaccine technologies into additional indications. In a joint press release with Vaxart, Inc., the companies announced an exclusive, worldwide license and collaboration agreement for Vaxart’s investigational oral COVID-19 vaccine candidate. Under this agreement, Dynavax receives an exclusive license to develop and commercialize oral COVID-19 vaccines based on Vaxart’s pill-based delivery platform, while Vaxart retains responsibility for development through completion of an ongoing Phase 2b trial and an End of Phase 2 meeting with the U.S. Food and Drug Administration. Dynavax has the right, but not the obligation, to assume further development and commercialization after reviewing Phase 2b data, and has agreed to potential milestone and royalty payments if it advances the program.
Dynavax has also described an exclusive license and collaboration agreement structure in the context of this oral COVID-19 vaccine program, emphasizing a phased approach that allows evaluation of clinical data before committing to late-stage development. This reflects a strategy of combining internal vaccine programs with selectively licensed external assets that can be supported by Dynavax’s commercial and development capabilities.

Use of Toll-like Receptor Immune Modulation
Polygon data and company descriptions highlight that Dynavax’s scientific approach centers on modulating the innate and adaptive immune responses through toll-like receptor stimulation, particularly TLR9. CpG 1018, described as a TLR9 agonist, is a key component of this approach. The technology is characterized as part of a Toll-like Receptor Immune Modulation Platform that plays a role in innate immunity and subsequent adaptive immunity. This platform underpins HEPLISAV-B, Z-1018 and multiple pipeline and partnered programs, and is a defining feature of the company’s research and development strategy.
Business Model Overview
Based on the company’s own statements and Polygon’s summary, Dynavax’s business model combines:
- Commercial sales of HEPLISAV-B, its adult hepatitis B vaccine.
- Commercial and partnered use of CpG 1018 adjuvant, including in HEPLISAV-B and adjuvanted COVID-19 vaccines.
- Internal development of vaccine candidates such as Z-1018 for shingles, a plague vaccine candidate, a pandemic influenza adjuvant program, and a Lyme disease vaccine candidate.
- Strategic collaborations and licensing arrangements, such as the exclusive license for Vaxart’s oral COVID-19 vaccine candidate.
