About Ryan Spencer
Ryan Spencer, CEO of Dynavax, discussed the company's recent performance and outlook during a March 2025 interview at the JP Morgan Healthcare Conference. He stated that the company's adult hepatitis B vaccine, which uses Dynavax's proprietary adjuvant, achieved record revenue of $268 million in 2024, with continuous growth since its 2018 launch. Spencer also announced that enrollment for a shingles vaccine clinical trial had been completed, with data expected in the third quarter of 2025, and described the adjuvant as having broad applicability for other vaccines, including a collaboration with Mount Sinai on a universal influenza vaccine program. Regarding vaccine hesitancy and political factors, Spencer said the company has "no real insight" into the agendas of political figures such as Trump administration cabinet picks or Robert F. Kennedy Jr., but expressed confidence that Dynavax's adult hepatitis B vaccine is "somewhat insulated" from the political polarization seen in pediatric vaccine mandates. He noted that while some population segments remain hesitant, a large portion of adults are still amenable to vaccination. Spencer described 2025 as a "transformational year" for Dynavax, citing upcoming shingles data and continued revenue growth, and said the company is actively seeking to acquire new assets that could benefit from its late-stage and commercial capabilities.
