Beijing, China - 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 approved by the Ministry of Health of the Kyrgyz Republic, the company's first direct authorization of a vaccine for market use in Kyrgyzstan.
The approval adds a powerful tool to the nation's fight against hepatitis transmission and infection. Once named a focus country for viral hepatitis by the World Health Organization (WHO), Kyrgyzstan has since taken measures to prevent and control the infectious disease. Hepatitis B vaccine has been included in Kyrgyzstan's national vaccination schedule since 2000, but hepatitis A vaccine is only available in the private sector for self-purchase.
According to the Department of Disease Prevention and State Sanitary and Epidemiological Surveillance, the first three quarters of 2022 saw a notable rise in reported cases of acute viral hepatitis in Kyrgyzstan. From January to September, 1,501 acute viral hepatitis cases were registered, a 25% increase compared to the same period in 2021.
Out of those cases, 1,388 hepatitis A cases contributed to 92.5% of the total incidences during that time frame, representing a year-on-year increase of 29%. A more accessible supply of hepatitis A vaccines in Kyrgyzstan will ensure local communities are better protected and will build on the country's success lowering transmission as the dominant cause of viral hepatitis cases.
Healive®, a SINOVAC flagship product, is the first and only hepatitis A vaccine from China pre-qualified by the WHO. It offers sustained protection for at least 30 years after full-course immunization, based on statistical modeling1.
The vaccine has been registered in 23 countries and organizations around the world, including Kyrgyzstan, and is currently authorized for administration in more than 30 countries and areas.
Healive® and SINOVAC's varicella vaccine, another WHO prequalified vaccine, can be administered simultaneously to children 1 year of age, to enhance vaccination efficiency and save cost and time for parents and doctors. According to a recent study2, delivering the doses together offers additional benefits by reducing pain and establishing earlier immunity.
