NEW YORK (Reuters) – Following is a brief summary of the latest scientific studies on the new coronavirus and efforts to find treatments and vaccines for COVID-19, the disease caused by the virus.

Antibody that "neutralizes" the new coronavirus

Researchers said on Monday that they produced a monoclonal antibody that can "neutralize" the new coronavirus (SARS-CoV-2) that causes COVID-19 disease. His experiments were carried out in test tubes, and it is still unclear exactly how the antibody blocks the virus. Reporting on their work in the journal Nature, European researchers say the antibody "offers the potential to prevent and / or treat COVID-19", but they also emphasize that further studies are needed before we know whether the antibody can be turned into a virus. drug that works in humans.

New details of the structure of the coronavirus may help in the development of the vaccine

New information released on Monday about the structure of the new coronavirus will help in the development of a vaccine, the researchers say. Vaccine research has focused on the so-called peak (S) glycoprotein, a "peak" that protrudes from the surface of the virus and helps to invade cells and infect them. Using high-resolution mass spectrometry, the US / UK research team documented previously unknown details about the peak that can provide vaccine developers with important clues on how best to reach it, according to their report in the journal Science .

French hospital discovers COVID-19 case from December

A French hospital that retested old samples from patients with pneumonia found that it had treated a man with COVID-19 as early as December 27, almost a month before the French government confirmed its first cases, and a time when the virus was believed to had been limited to China only. The researchers who reported this finding in the International Journal of Antimicrobial Agents say it "changes our understanding of the epidemic" and the models used to predict how the virus spreads may be based on incorrect data.
