New Delhi : Immunization with a combination of first dose of Covishield followed by second dose of Covaxin is not only safe but also elicits better immunogenicity, the Indian Council of Medical Research (ICMR) said on Sunday, citing its preprint research. When peer reviewed and recognized, the research may pave the way for more flexibility in mixing and matching covid-19 vaccines in India.
Immunization programme against covid-19 in India started with two vaccines Covishield and Covaxin on January 16. While Covishield is the in-country version of Oxford-AstraZeneca vaccine manufactured by Serum Institute of India (SII), Covaxin is an inactivated whole virus vaccine (BBV152) developed jointly by ICMR -National Institute of Virology (ICMR-NIV) and Bharat Biotech International Ltd.
