Covid: ‘Warm’ vaccine found effective against all variants, says report

BENGALURU: A ‘warm’ vaccine formulation developed by scientists at IISc in conjunction with biotech firm Mynvax is effective against all current SARS-CoV-2 variants of concern, an independent evaluation of the formulation conducted by CSIRO, Australia has shown. CSIRO found that the ‘warm’ vaccine helps produce antibodies that neutralise all current variants of the novel coronavirus.
The findings were published on Thursday in the peer-reviewed ACS Infectious Diseases journal. This will pave the way for clinical development of the vaccine, leading to human trials. The study was led by Prof Raghavan Varadarajan of IISc. TOI first reported about the vaccine in November 2020. Researchers have shown the formulation remained stable at 37°C for a month and at 100°C for up to 90 minutes — living up to its ‘warm vaccine’ tag.
