Covaxin for children proven to be safe in paediatric subjects in study: Bharat Biotech

New Delhi | Hyderabad based vaccine manufacturer Bharat Biotech on Thursday announced that BBV152 (Covaxin), its whole-virion inactivated COVID-19 vaccine candidate, has proven to be safe, well-tolerated, and immunogenic in paediatric subjects in phase II/III study.

The vaccine manufacturer had conducted phase II/III, open-label, and multicentre studies to evaluate the safety, reactogenicity, and immunogenicity in healthy children and adolescents in the 2-18 age group. The clinical trials conducted in the paediatric population between June 2021 to September 2021 have shown robust safety, reactogenicity, and immunogenicity. The data was submitted to the Central Drugs Standard Control Organisation (CDSCO) during October 2021 and received emergency use nod for children aged 12-18 from DCGI recently.

Dr Krishna Ella, Chairman and Managing Director, Bharat Biotech, said, “Covaxin’s clinical trial data from the paediatric population is very encouraging. Safety of the vaccine is critical for children, and we are glad to share that COVAXIN has now proven data for safety and immunogenicity in children. We have now achieved our goal of developing a safe and efficacious COVID-19 vaccine for adults and children. Vaccines are a great preventive tool; the power of vaccines can only be harnessed if used prophylactically.”

In the study, no serious adverse event was reported. 374 subjects reported either mild or moderate severity symptoms with 78.6 per cent getting resolved within one day. Pain at the injection site was the most commonly reported adverse event, claimed Bharat Biotech in the statement.

For the trial, 976 subjects were screened for SARS-CoV-2 by RT-PCR and ELISA testing. Out of these, 525 eligible participants were enrolled. Based on the age, participants were distinguished into three groups in an age de-escalatory manner. Group I consisted of children of age 12-18 years (n175), group II consisted of children of age 6-12 years (n175), and group III consisted of children of age 2-6 years (n175). Seroconversion was documented at 95-98%, in all three groups four weeks after the second dose, indicating superior antibody responses in children when compared to adults and also displayed Th1 bias, said vaccine manufacturer.
