In January of 2021 a new lineage of SARS-CoV-2, known as P.1 and named as Gamma variant, was discovered in Japan and later spread in Brazil. It is considered as VOC (variant of concern). This variant carries 10 mutations in spike protein, including N501Y, E484K and K417T in RBD, which can increase the affinity to the human ACE2 receptor. Enhanced transmission of the Gamma variant (P.1 lineage) was observed globally, which is 3.5 times more contagious as the original one. The Gamma variant affects the effectiveness of COVID19 vaccine and is resistant to neutralization to some extent due to the immune escape E484K mutation.
