SINOVAC's Hepatitis A Vaccine Healive^® Launched in Indonesia

December 6, 2022, Jakarta -- Sinovac Biotech Ltd. ("SINOVAC" or the "Company") (NASDAQ: SVA), a leading provider of biopharmaceutical products in China, announced that its inactivated hepatitis A vaccine, Healive^®, has been launched in Indonesia, under the cooperation with its local partner, PT Etana Biopharmaceutical Indonesia.

As one of SINOVAC's flagship products, Healive^® is the first and only hepatitis A vaccine from China, which passed the assessment under WHO Prequalification Procedures. It offers sustained protection for 30+ years after full-course immunization, based on output of statistical modeling¹.

Healive^® was approved by BPOM, the food and drug agency of Indonesia, in February 2022. Including Indonesia, the Company's hepatitis A vaccine has been registered in 21 countries and organizations around the world and authorized to be administered in 33 countries and regions, to susceptible people aged over 12 months.

According to the World Health Organization's report, the Southeast Asia region had the greatest number of estimated hepatitis A cases and deaths between 2010 and 2019.

The hepatitis A disease is a public health challenge in Indonesia. The lower prevalence of anti-HAV among children on the island of Java had caused more frequent hepatitis A outbreaks. Currently, children and adults are recommended to take a 2-dose treatment of hepatits A vaccination by local healthcare organizations in Indonesia that include the Indonesian Pediatric Society and Indonesian Society of Internal Medicine.
