Covaxin Offers Protection Against Multiple Variants: Study
“We studied in a cohort for six months where Covaxin induced good memory response. So we are confident that till six months of full immunisation, no booster dose is required. A follow up of this cohort thereafter, will help us to understand if we really need booster shots or not,” said Dr Nimesh Gupta, corresponding author of the study at NII. “The best protection was found against alpha then delta and the least was against beta variants,” he added.
