The Omicron variant that is calling the shots globally is around three times more transmissible than Delta among vaccinated individuals. China’s BF.7 is BA. sub-lineage of Omicron BA.5. BF.7 has R346T mutation in spike protein of the virus and can escape antibodies that have been derived from the vaccines targeted to the original Wuhan virus, especially the Chinese vaccine Sinovac.

At present the virus found in China is BF.7. Similar growth has been observed in many other countries including Japan, South Korea, UK, Brazil and USA and the surge in Covid 9 in these countries is due to BF.7.
