Inspired by llamas, scientists make potent anti-coronavirus agent

Inspired by a unique kind of infection-fighting antibody found in llamas, alpacas, and other camelids, a research team at the University of California, San Francisco, has synthesized a molecule that they say is among the most potent anti-coronavirus compounds tested in a lab to date

Coronavirus: Immunity may be more widespread than tests suggest

For every person testing positive for antibodies, two were found to have specific T-cells which identify and destroy infected cells. This was seen even in people who had mild or symptomless cases of Covid-19. But it's not yet clear whether this just protects that individual, or if it might also stop them from passing on the infection to others.

Regeneron Starts Phase 3 Trial For Coronavirus Antibody Cocktail

Regeneron Pharmaceuticals has started late-stage clinical trials evaluating REGN-COV2, its investigational double antibody cocktail for the treatment and prevention of COVID-19. A Phase 3 trial will evaluate REGN-COV2's ability to prevent infection among uninfected people who have had close exposure to a COVID-19 patient.

Getting Covid-19 twice: Why I think my patient was reinfected

“Wait. I can catch Covid twice?” my 50-year-old patient asked in disbelief. It was the beginning of July, and he had just tested positive for SARS-CoV-2, the virus that causes Covid-19, for a second time — three months after a previous infection. While there’s still much we don’t understand about immunity to this new illness, a small but growing number of cases like his suggest the answer is “yes.”

Immunity to Covid-19 could be lost in months, UK study suggests

People who have recovered from Covid-19 may lose their immunity to the disease within months, according to research suggesting the virus could reinfect people year after year, like common colds. Blood tests revealed that while 60% of people marshalled a “potent” antibody response at the height of their battle with the virus, only 17% retained the same potency three months later.

Coronavirus Drug and Treatment Tracker

Below is an updated list of 19 of the most-talked-about treatments for the coronavirus. While some are accumulating evidence that they’re effective, most are still at early stages of research. We also included a warning about a few that are just bunk.

The people with hidden immunity against Covid-19

In short, though antibodies have proved invaluable for tracking the spread of the pandemic, they might not have the leading role in immunity that we once thought. If we are going to acquire long-term protection, it looks increasingly like it might have to come from somewhere else.
