The Regional Medical Research Centre for North East Region located in Dibrugarh has become the fourth laboratory in India to successfully isolate the SARS-CoV-2 (COVID-19) virus which can be used in the production of a vaccine against the contagion in future.
Before RMRC, two other government laboratories that include National Institute of Virology (NIV) Pune, and the Centre for Cellular and Molecular Biology (CCMB) Hyderabad, had isolated the virus.
All the virus strains circulating in Assam were of L-typeBharat Biotech along with NIV, Pune, which supplied the virus grown in tissue culture, has developed an inactivated COVID-19 vaccine (COVAXIN). Two types of the virus namely, the L-type and the S-type have been noted so far and according to the scientists the S-type is slowly disappearing.
All the strains circulating in Assam were of L-type but now scientists have classified the virus into different clades (O, A1, A2a, A3, B, B1, etc), which differ from each other very minutely. According to the scientists, the A2a clade is now the most dominant across the world, including India.
