Mixing Covaxin, Covishield doses shows better results than 2 shots of same vaccine: ICMR

The Indian Council of Medical Research (ICMR) has said that a study on mixing and matching of two COVID vaccines – Covaxin and Covishield – showed that combining these two COVID-19 vaccines elicited better immunogenicity than two doses of the same vaccine.

The study, by Pune-based National Institute of Virology (NIV), suggested that immunisation with combination of Covishield and Covaxin was safe and provides better immunity against COVID-19 variants.

"The findings suggested that immunisation with a combination of an adenovirus vector platform-based vaccine followed by an inactivated whole virus vaccine was not only safe but also elicited better immunogenicity," the study said.
