Scientist —Discovered Antibody Capable of successfully Fight against any mutant variants of Covid-Virus

SCIENTISTS have discovered new antibodies that could wipe out virtually all known Covid variants.

They were isolated from the blood of a patient who recovered from SARS in the early 2000s and received a Corona Virus Vaccine in 2021.

Researchers at Duke-NUS Medical School in Singapore who led the study, said: “This unique combination of prior coronavirus infection and vaccination generated an extremely broad and powerful antibody response capable of stopping nearly all related coronaviruses tested.”

The team identified six antibodies that could neutralize multiple viruses including SARS-CoV-2 (Covid-19) and its variants Alpha, Beta, Gamma, Delta and Omicron, the original SARS virus, and multiple other animal coronaviruses transmitted from bats and pangolins.

The most powerful, E7, neutralized both SARS-CoV and SARS-CoV-2 sarbecoviruses, animal sarbeco viruses and newly emerged SARS-CoV-2 strains, such as Omicron XBB.1.16

The authors said it targets a particular weakness in the virus’ spike protein, which it uses to invade cells.

E7 appears to block the shape-shifting process the virus requires to infect cells and cause illness, they added.

First author Dr Chia Wan Ni said: “The neutralizing potency and breadth of the E7 antibody exceeded any other SARS-related coronavirus antibodies we’ve come across.

“It maintained activity against even the newest Omicron subvariants, while most other antibodies lose effectiveness.”

The findings help unmask the weak spots of coronaviruses and provide templates for designing vaccines and other drugs that work against variants and potential future outbreaks.
