MUMBAI : Answers to whether India should mix covid-19 vaccines and give booster doses could be in by the end of January, as a study to check their effectiveness nears its last stage.
CMC Vellore is nearing the end of its study on mixing doses, including of Covaxin and Covishield, said Gagandeep Kang, leading virologist and professor at the medical research institution.
Research has shown that mixing two different vaccine platforms such as an mRNA platform and an adenovirus platform (eg; Pfizer and AstraZeneca vaccines) provides better immune response to the SARS CoV-2 virus.
India’s study, the first of its kind, will find out whether the inactivated and adenovirus platforms also offer similar response.
