Covaxin's animal trials successful

Earlier in September, Bharat Biotech had informed that Covaxin had proved to be effective in inducing immunity against COVID-19 in animals. The firm had stated that two-dose vaccination regimen of inactivated SARS-CoV-2 vaccine candidates was administered in 20 rhesus macaques which were divided into four groups equally. The results showed protective efficacy, increasing SARS-CoV-2 specific IgG and neutralizing antibodies, reducing replication of the virus in the nasal cavity, throat, and lung tissues of monkey.
