The study was conducted between May and June this year in Uttar Pradesh. It was conducted after the go-ahead from the Drugs Controller General of India, noted that the combination was safe.
On July 30, a Subject Expert Committee of the Central Drugs Standard Control Organisation (CDSCO) recommended conducting a study on mixing doses of Covishield and Covaxin vaccines. The recommendation came following an application by Christian Medical College (CMC), Vellore.
According to the Union health ministry, the vaccination coverage in the country has crossed 50.68 crores.
Overall, over 50.68 crore vaccine doses have been administered through 58,51,292 sessions.
WHO on mixing the vaccines:
WHO chief scientist Soumya Swaminathan in July this year, advised against mixing and matching Covid-19 vaccines from different manufacturers. She says it is a “dangerous trend” since there was little data available.
“There is limited data on mix and match. It will be a confusing situation in countries if citizens start deciding when and who will be taking a second, a third, and a fourth dose,” Soumya Swaminathan said.
