The scientists said they have found the first antibody that can attack the protein fragment that helps corona viruses attach to human body cells, thereby neutralizing them.

SCMP said on Monday that scientists in the United States and Belgium have found antibodies to neutralize the Sars-CoV-2 virus, the official name for the corona virus that caused the Covid-19 pandemic. Jason McLellan, an expert from the University of Texas, says these are “the first known antibodies that can neutralize viruses”.

“With antibody therapy, we will put the protective antibodies directly into the human body, who will immediately be protected after treatment,” McLellan said.

American experts say antibodies can also be used on people who have been seriously ill, helping to reduce illness.

Scientists in the project have spent years researching corona virus strains, including the one causing the SARS and MERS pandemics. In 2016, scientists transmitted the virus to llamas, in the hope of developing a new treatment for these diseases.

“At first, we thought this was just a small project. But now, the scientific impact of the project may be greater than all I could imagine,” said Dorien De Vlieger, a Belgian expert from Dai. Ghent learn, said.

The tumor-free camel immune system produces two types of antibodies when it detects foreign viruses, a type similar to human antibodies of a smaller size. Camel-produced antibodies have been found to be effective in targeting the corona virus’s pointed protein, which helps the virus attach to human cells.

Daniel Wrapp, an expert from the University of Texas, said the camel’s smaller size antibody could be used in breathing therapy.

“This helps the antibody potentially be used as a drug to treat respiratory diseases, because we can take them to the right place where they are infected,” Wrapp said.

Scientists say more research needs to be done. Currently, scientists are preparing antibody tests for mice to test the response of antibodies, before moving on to human trials.
