Chilean Report Confirms CoronaVac Safety for Pediatric and Adolescent Population
On May 20, 2022, the Public Health Institute of Chile (ISP) released the fourth statistical report "AEFIs after the administration of SARS-CoV-2 vaccines in Chile in the pediatric and adolescent population." The findings confirm the CoronaVac® COVID-19 vaccine manufactured by Sinovac Biotech Ltd., (SINOVAC) is safe for children aged 3 and above.
The report evaluated 6,946,593 SARS-CoV-2 vaccine doses that were administered to children and adolescents from March 1, 2021, to February 26, 2022. More than 70% were administered with SINOVAC’s COVID-19 vaccine, which has been approved for minors as young as 3. The rest were administered with mRNA vaccine manufactured by Pfizer-BioNTech, which has been approved for children 5 years and older. SINOVAC manufactures the only COVID-19 vaccine that is available to children in Chile between the ages of 3 to 5.
In total, 868 adverse events following immunization (AEFI) were reported at a rate of 12.50 AEFI notifications per 100,000 doses administered. For CoronaVac®, the rate was 10.67. Among all AEFIs, 107 cases were classified as serious, at a rate of 1.54 serious AEFI notifications per 100,000 doses administered. Similarly, a lower rate of 1.31 was observed for the SINOVAC COVID-19 vaccine.
These results are consistent with prior studies supporting the safety and effectiveness of CoronaVac® for use in minors for both primary vaccination and booster shots. The latest results from pediatric phase II clinical trials in China also suggest that a third dose of CoronaVac® shows good protection against the Omicron variant, particularly in younger children aged 3 to 5 years old.
CoronaVac® has been approved for use in children and adolescents in 14 countries and regions, offering protection to more than 280 million children worldwide.
