Cost of Sales - Product. Cost of sales - product for the fourth quarter of 2021 increased to $74.0 million, compared to $4.1 million for the fourth quarter of 2020. Full year 2021 cost of sales - product was $173.6 million compared to $11.4 million for the full year of 2020.  The increase was primarily due to manufacturing costs for increased volumes of CpG 1018 sold to COVID-19 supply partners, and HEPLISAV-B sales, coupled with approximately $4.8 million in excess capacity charges in connection with an expansion project at the Company's manufacturing facility in Dusseldorf and $2.6 million write-off of HEPLISAV-B inventory that had been manufactured prior to the beginning of the COVID-19 pandemic and not expected to be sold due to the prolonged impact of the pandemic.

Research and Development Expenses (R&D). R&D expenses for the fourth quarter of 2021 increased to $11.1 million, compared to $9.5 million for the fourth quarter of 2020. Full year 2021 R&D expenses were $32.2 million compared to $28.6 million for the full year 2020. The increase in both periods was primarily driven by higher compensation and personnel costs, including non-cash stock-based compensation, associated with higher headcount and external costs as the Company advances its product candidates with CpG 1018 adjuvant through pre-clinical and clinical collaborations and additional discovery efforts.

Selling, General and Administrative Expenses (SG&A). SG&A expenses for the fourth quarter of 2021 increased to $29.2 million, compared to $17.8 million for the fourth quarter of 2020. Full year 2021 SG&A expenses were $100.2 million compared to $79.3 million for the full year 2020. The increase in both periods was primarily driven by compensation and related personnel costs, including non-cash stock-based compensation, associated with higher headcount as the Company expanded its field sales team to increase HEPLISAV-B market share.

Interest Expense. Interest expense was $1.7 million in the fourth quarter of 2021 and $11.2 million for the full year 2021, primarily in connection with the convertible senior notes due 2026.

Other income (expense). Other income (expense) includes the change in fair value of warrant liability which is a non-cash adjustment to fair value each reporting period. The change in fair value of warrant liability for the fourth quarter of 2021 resulted in a gain of $19.2 million, compared to a loss of $0.1 million in the fourth quarter of 2020.

Income Tax Expense. Income tax expense was $0.8 million for the full year 2021 and the Company's effective tax rate was 1.03%. No income tax expense was recorded for the full year 2020. The increase in income tax expense and the effective tax rate are both due to achieving the Company's first profitable year with GAAP net income of $76.7 million.

Net Income (Loss).  GAAP net income was $99.8 million, or $0.80 per share (basic) and 0.55 per share (diluted) in the fourth quarter of 2021, compared to GAAP net loss in the fourth quarter of $15.5 million, or $0.14 per share (basic) and $0.14 per share (diluted) in the fourth quarter of 2020.  GAAP net income was $76.7 million, or $0.62 per share (basic) and $0.57 per share (diluted) for the full year 2021, compared to GAAP net loss of $75.2 million, or $0.75 per share (basic) and $0.78 per share (diluted) for the full year 2020.

About Hepatitis B
Hepatitis B is a viral disease of the liver that can become chronic and lead to cirrhosis, liver cancer and death. The hepatitis B virus is 50 to 100 times more infectious than HIV,ⁱ and transmission is on the rise. There is no cure for hepatitis B, but effective vaccination can prevent the disease.

In adults, hepatitis B is spread through contact with infected blood and through unprotected sex with an infected person. The U.S. Centers for Disease Control (CDC) recommends vaccination for those at high risk for infection due to their jobs, lifestyle, living situations and travel to certain areas.ⁱⁱ Because people with diabetes are particularly vulnerable to infection, the CDC recommends vaccination for adults age 19 to 59 with diabetes as soon as possible after their diagnosis, and for people age 60 and older with diabetes at their physician's discretion.ⁱⁱⁱ Approximately 26 million U.S. adults have diabetes, and 1.5 million new cases of diabetes are diagnosed each year.^iv

About HEPLISAV-B
HEPLISAV-B is an adult hepatitis B vaccine that combines hepatitis B surface antigen with Dynavax's proprietary Toll-like Receptor (TLR) 9 agonist CpG 1018 to enhance the immune response. Dynavax wholly owns HEPLISAV-B.

Important U.S. Product Information
HEPLISAV-B is indicated for prevention of infection caused by all known subtypes of hepatitis B virus in adults age 18 years and older.

Safety and effectiveness of HEPLISAV-B have not been established in adults on hemodialysis.

For full U.S. Prescribing Information for HEPLISAV-B, click here.

Important U.S. Safety Information (ISI)
Do not administer HEPLISAV-B to individuals with a history of severe allergic reaction (e.g., anaphylaxis) after a previous dose of any hepatitis B vaccine or to any component of HEPLISAV-B, including yeast. Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of HEPLISAV-B. Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to HEPLISAV-B. Hepatitis B has a long incubation period. HEPLISAV-B may not prevent hepatitis B infection in individuals who have an unrecognized hepatitis B infection at the time of vaccine administration. The most common patient reported adverse reactions reported within 7 days of vaccination were injection site pain (23% to 39%), fatigue (11% to 17%) and headache (8% to 17%).

Important EU/EEA Product Information
HEPLISAV B is indicated for active immunization against hepatitis B virus infection (HBV) caused by all known subtypes of hepatitis B virus in adults 18 years of age and older.
The use of HEPLISAV B should be in accordance with official recommendations.
It can be expected that hepatitis D will also be prevented by immunization with HEPLISAV B as hepatitis D (caused by the delta agent) does not occur in the absence of hepatitis B infection.

For full EU/EEA. Prescribing Information for HEPLISAV-B, click here.

Important EU/EEA Safety information
Do not receive HEPLISAV B if you have had a sudden life-threatening, allergic reaction after receiving HEPLISAV B in the past, or if you are allergic to any of components of this vaccine, including yeast. Signs of an allergic reaction may include itchy skin, rash, shortness of breath and swelling of the face or tongue.

Appropriate medical treatment and supervision should be readily available in case of rare anaphylactic reactions following the administration of the vaccine.
The administration of HEPLISAV B should be postponed in subjects suffering from acute severe febrile illness.

Immunocompromised persons may have a diminished immune response to HEPLISAV B.
Because of the long incubation period of hepatitis B, it is possible for unrecognized HBV infection to be present at the time of immunization. HEPLISAV B may not prevent HBV infection in such cases.
There are very limited data on the immune response to HEPLISAV B in individuals who did not mount a protective immune response to another hepatitis B vaccine.

As a precautionary measure, it is preferable to avoid the use of HEPLISAV B during pregnancy. Vaccination during pregnancy should only be performed if the risk-benefit ratio at the individual level outweighs possible risks for the fetus.

The most common patient-reported side effects reported within 7 days of vaccination were pain, swelling or redness at the injection site, feeling tired, headache, muscle aches, feeling unwell and fever.

About CpG 1018 Adjuvant
Dynavax developed CpG 1018 adjuvant to provide an increased vaccine immune response with improved tolerability profile, which has been demonstrated in HEPLISAV-B and two COVID-19 vaccines that have received Emergency Use Authorization. CpG 1018 adjuvant provides a well- developed technology and a significant safety database, potentially accelerating the development and large-scale manufacturing of novel or improved vaccines.
