WHO Extended the Use of SINOVAC COVID-19 Vaccine under EUL to Individuals Aged 3 Years and Above

November 22, 2022, Beijing -- Sinovac Biotech Ltd. ("SINOVAC" or the "Company") (NASDAQ: SVA), a leading provider of biopharmaceutical products in China, announced that its COVID-19 vaccine, CoronaVac®, recently has been validated by the World Health Organization ("WHO") for extended use in children as young as three years old under Emergency Use Listing ("EUL") Procedure. This is the youngest age that the WHO has validated for EUL of COVID-19 vaccines in the world so far.


Prior to this, CoronaVac® has been validated for emergency use under the WHO EUL procedure and recommended by the Strategic Advisory Group of Experts on Immunization ("SAGE") for use in all individuals aged 18 and above, in June 2021.


In an effort to provide protection for a larger number of populations, SINOVAC initiated global clinical studies of CoronaVac® among children since 2021. Preliminary study results show that CoronaVac® reduced COVID-19 infection, COIVD-related hospitalization and ICU admission in children aged three to five years during the Omicron outbreaks; the vaccine provided over 90% effectiveness against hospitalization and ICU admission in children and adolescents six to 16 years-old, when Delta variant was prevalent; and the vaccine provided over 95% effectiveness against moderate to severe cases in children and adolescents three to 18 years-old, when Omicron BA.2 was predominant.


Up to now, with more than 2.9 billion doses shipped globally, CoronaVac® has been approved for use in more than 60 countries and regions worldwide, among which, more than a dozen of authorities in Asian, Latin American, and African regions have approved the vaccines’ use in minors, before the WHO's extension to children.


CoronaVac® has been approved for emergency use in children six months and older in Chile and for off-label use in children 6 to 35 months old in Hong Kong, marking the only inactivated COVID-19 vaccine approved for children as young as six months old in the world.
