Mixing Covaxin and Covishield safe, gives better immune response: ICMR

The study was conducted on 18 individuals who inadvertently received Covishield as first jab and Covaxin as second in UP at a gap of six weeks

A study by Indian Council of Medical Research has found that mixing the doses of Covishield and Covaxin was not only safe but also elicited a better immune response.
