One of the pilot studies conducted by the Indian Council of Medical Research (ICMR) shows that a single dose of Covaxin on people recovered from Covid-19 is as effective as two doses administered to uninfected individuals.
ICMR has asserted that these are only preliminary findings and that it needs to be corroborated with larger units of data.
Moreover, the authors of the research maintain that taking both doses of the vaccine developed by Bharat Biotech is still recommended.
This study conducted by the ICMR involved frontline and healthcare workers that were examined for e SARS-CoV-2–specific antibody responses after day zero (baseline, before vaccination), Day 28 (month 1) and Day 56 post-first dose (month 2) of Covaxin.
“This study offers evidence in support of public health-oriented and immunologically sustained vaccine strategies,” the study published by ICMR reads, as reported by the Economic Times.
It added, “If our preliminary findings are confirmed in large population studies, a single dose of BBV152 vaccine may be recommended to previously confirmed SARS-CoV-2 infected individuals so that the naïve individuals could attain the larger benefit of a limited vaccine supply.”
