Dynavax developed its CpG 1018 adjuvant to provide an increased vaccine immune response with an improved tolerability profile. The adjuvant has a well-established safety and efficacy profile as demonstrated in global clinical trials and commercial use. CpG 1018 adjuvant is contained in Dynavax's U.S. FDA- and European Commission-approved adult hepatitis B vaccine, as well as in two COVID-19 vaccines that have received regulatory approval or authorization.

For COVID-19 specifically, Dynavax is supporting vaccine development by providing CpG 1018 adjuvant through CSAs supporting four geographically and technologically diversified vaccines, which generated over $197 million in revenue through the first three quarters of 2021.
