NEW DELHI : India’s top vaccine advisory body has sought laboratory data and more evidence from Christian Medical College (CMC) Vellore which is conducting a study on mixing covid-19 vaccines Covaxin and Covishield, a person aware of the development said.
Recently, CMC Vellore submitted preliminary findings of the study to the National Technical Advisory Group On Immunization (NTAGI), which makes vaccine recommendations after reviewing data on disease burden, efficacy and cost effectiveness. “We have reviewed the preliminary data and we realized there is need of more laboratory-based evidence.
CMC Vellore is working on it and they have asked for at least six weeks to submit the laboratory data," the person cited above said on condition of anonymity.
Under India’s vaccine mixing protocol, an individual who is fully vaccinated with vaccine ‘A’ receives a booster dose of vaccine ‘B’, and vice versa.
