BEIJING-- July 15, 2022 -- Sinovac Biotech Ltd. (“SINOVAC” or the “Company”) (NASDAQ: SVA), a leading provider of biopharmaceutical products in China, announced that its COVID-19 vaccine (CoronaVac) has been approved by the Brazilian Health Regulatory Agency (Anvisa) for emergency use in children from 3 to 5 years old on 13 July. These children will receive the same dose that is already applied to minors aged 6 to 17 years and adults and there is no restriction on the application for immunosuppressed children aged 3 to 5 years.

This authorization was given under comprehensive evaluations based on analysis results from all available data on the vaccine and its use in children.

Participants in this evaluation activity were the Brazilian Society of Pediatrics (SBP), the Brazilian Society of Infectious Diseases (SBI), the Brazilian Society of Pneumology and Phthisiology (SBPT), the Brazilian Society of Immunizations (SBIm), and the Brazilian Association of Collective Health (Abrasco). To assist Anvisa in evaluating the vaccine, the experts from the above institutions had access to technical materials and research data on the vaccine.
