The Hyderabad-based Bharat Biotech has admitted on the Lancet Infectious Diseases study on the effectiveness of COVAXIN (BBV152) against symptomatic RT-PCR, saying that the results compare favourably to the 65.2 percent efficacy against Delta variant obtained during controlled phase 3 clinical trials of COVAXIN in the general population.
"These findings are comparable to the 65.2 percent efficacy against the delta variant found in COVAXIN's controlled phase III clinical trials in the general population. COVAXIN also passes the WHO efficacy standards for COVID-19 vaccinations against the feared Delta variant, according to the findings "According to Bharat Biotech.
According to the first real-world assessment of the COVID-19 vaccine published in the Lancet Infectious Diseases journal, two doses of COVID-19 vaccine Covaxin (BBV152) are 50 percent efficacious against symptomatic COVID-19 disease.
