According to the scientists, the two strains first described in Brazil and Japan were five to seven times more resistant, compared to the original SARS-CoV-2 virus lineage from Wuhan, China.

Boston:  March 13, 2021 Antibodies raised by some COVID-19 vaccines are less effective at neutralising new, circulating variants of the novel coronavirus such as the ones first reported in the UK, South Africa and Brazil, according to a new study. The research, published in the journal Cell, noted that the neutralising antibodies induced by the Pfizer and Moderna COVID-19 vaccines were less effective against the coronavirus variants first described in Brazil and South Africa. According to the scientists, including Alejandro Balazs from the Massachusetts General Hospital (MGH) in the US, neutralising antibodies work by binding tightly to the virus and blocking it from entering cells, thus preventing infection. They said this binding only happens when the antibody’s and the virus’ shapes are perfectly matched to each other “like a key in a lock.”
