Newly discovered antibodies could be the key to fighting off every strain of Covid. Researchers have uncovered six new antibodies in the blood of patients who had survived Covid-19's early ancestor, the SARS virus of 2002, who then also received a vaccination against the coronavirus in more recent years. The most powerful, E7, was found to neutralize newly emerged SARS-CoV-2 variants, such as  Omicron  XBB.1.16, which has caused a more than 14 percent spike in new US cases over the past month. But the cases are still at a historic low compared to previous years since the virus first took hold of the world in 2020.  The international team of scientists, led by Duke-NUS Medical School in Singapore, found E7 blocks the shape-shifting process the virus requires to infect cells and cause illness. The new results come amid a surge in Covid cases across the US, including a 10-percent rise in hospitalizations, which jumped from 6,444 cases in the first week of...

In this article, we will do a roundup and cover 3 popular anti-viral treatments i.e. Remdesivir, Bebtelovimab and Sotrovimab. Bebtelovimab (Monoclonal Antibody) Bebtelovimab is an US FDA-authorized investigational monoclonal antibody treatment that was developed by Eli Lilly.  Is bebtelovimab effective against omicron: Data showing bebtelovimab’s efficacy against Omicron and its BA.2 subvariant prompted the FDA to authorize the drug through an EUA. A lab study published in July 2022 ( NEJM ) using the live-virus Focus Reduction Neutralization Testing (FRNT) method revealed that bebtelovima...
