Effective therapies are urgently needed for COVID-19. We rapidly (within a week) identified a fully human monoclonal germline-like antibody (ab1) from phage-displayed libraries that potently inhibited mouse ACE2-adapted SARS-CoV-2 replication in wild-type BALB/c mice and native virus in transgenic mice expressing human ACE2 as well as in hamsters when administered before virus challenge. It was also effective when administered after virus infection of hamsters, although at lower efficacy than when used prophylactically. Ab1 was highly specific and did not bind to human cell membrane-associated proteins. It also exhibited good developability properties including complete lack of aggregation. Ab1 has potential for prophylaxis and therapy of COVID-19 alone or in combination with other agents. Effective therapies are urgently needed for the SARS-CoV-2/COVID-19 pandemic. We identified panels of fully human monoclonal antibodies (mAbs) from large phage-displayed Fab, scFv, and VH libraries by panning against the receptor binding domain (RBD) of the SARS-CoV-2 spike (S) glycoprotein. A high-affinity Fab was selected from one of the libraries and converted to a full-size antibody, IgG1 ab1, which competed with human ACE2 for binding to RBD. It potently neutralized replication-competent SARS-CoV-2 but not SARS-CoV, as measured by two different tissue culture assays, as well as a replication-competent mouse ACE2-adapted SARS-CoV-2 in BALB/c mice and native virus in hACE2-expressing transgenic mice showing activity at the lowest tested dose of 2 mg/kg. IgG1 ab1 also exhibited high prophylactic and therapeutic efficacy in a hamster model of SARS-CoV-2 infection. The mechanism of neutralization is by competition with ACE2 but could involve antibody-dependent cellular cytotoxicity (ADCC) as IgG1 ab1 had ADCC activity in vitro. The ab1 sequence has a relatively low number of somatic mutations, indicating that ab1-like antibodies could be quickly elicited during natural SARS-CoV-2 infection or by RBD-based vaccines. IgG1 ab1 did not aggregate, did not exhibit other developability liabilities, and did not bind to any of the 5,300 human membrane-associated proteins tested. These results suggest that IgG1 ab1 has potential for therapy and prophylaxis of SARS-CoV-2 infections. The rapid identification (within 6 d of availability of antigen for panning) of potent mAbs shows the value of large antibody libraries for response to public health threats from emerging microbes.

Immunity to Covid Decreasing Per New Study - One Green Planet

By now, nearly everyone in the world is well aware that face masks are one of the most beneficial tools in the global war against COVID-19. (Whether or not everyone in the world follows, or believes, that science is a different story.) Not only are protective face coverings recommended by the CDC and Dr. Anthony Fauci, the nation's top infectious disease expert, but masks are mandatory in many places, and perhaps the easiest way to prevent the spread of the deadly virus. However, when you wear your face mask can make all the difference. According to a new study courtesy of the CDC, if you really want to ensure protection from the virus, you should also be wearing them in the comfort of your own home—if someone in your home gets sick.The study, published Friday on the CDC's website, found that "Transmission of SARS-CoV-2 occurs within households" and is quite common—mostly due to the fact that people spread the virus to family members before they are symptomatic. The one thing you can do to keep yourself protected from COVID is by wearing a mask around loved ones if they contract the virus. It doesn't guarantee 100% protection but it is "one of the most powerful weapons we have." (Related: Sure Signs You've Already Had Coronavirus.)"Household transmission of SARS-CoV-2 is common and occurs early after illness onset," the CDC wrote. "Persons should self-isolate immediately at the onset of COVID-like symptoms, at the time of testing as a result of a high risk exposure, or at time of a positive test result, whichever comes first." "Concurrently, all household members, including the index patient, should start wearing a mask in the home, particularly in shared spaces where appropriate distancing is not possible," they continued. "Close household contacts of the index patient should also self-quarantine, to the extent possible, particularly staying away from those at higher risk of getting severe COVID-19.""We are not defenseless against COVID-19," CDC Director Dr. Robert R. Redfield said earlier this year. "Cloth face coverings are one of the most powerful weapons we have to slow and stop the spread of the virus – particularly when used universally within a community setting. All Americans have a responsibility to protect themselves, their families, and their communities."One example of the effectiveness of face masks was demonstrated by a CDC report published over the summer about two hairdressers who were infected with COVID-19. Neither spread the virus to their clients, likely due to the fact that both of them wore masks. Dr. Fauci has even gone so far as to say he supports a nationwide mask mandate. "Whenever we looked around at what other countries have done, and even in individual situations in our own country, there is no doubt that masking—if you put masking with keeping distances and avoiding congregates and crowds and try to do the thing outdoors more than indoors, it makes a difference. It really, really does."

'More contagious' Covid mutation 'accounts for 85% of global cases' | Metro News

Official site of The Week Magazine, offering commentary and analysis of the day's breaking news and current events as well as arts, entertainment, people and gossip, and political cartoons. T-cell immunity against the coronavirus could last for at least six months after infection, a study from the U.K. Coronavirus Immunology Consortium suggests. The study, which is awaiting peer review, evaluated 100 health-care workers in the U.K. who had mild or asymptomatic COVID-19 cases in March and April and found that the defensive blood cells, which differ from antibodies, were present in all of them. The patients who experienced symptoms had T-cell levels that were at least 50 percent higher than the asymptomatic cases. That could mean either that people who had a more severe initial infection have more protection, or that those with milder or asymptomatic cases are able to control the virus with lower T-cell levels, The Guardian notes. The results are promising, especially given that other recent studies have suggested antibodies are waning in the general population, but not definitive. Fiona Watt, the executive chair of the U.K.'s Medical Research Council, was optimistic, especially in terms of what it could mean for vaccine development. "If natural reinfection with the virus can elicit a robust T-cell response, then this may mean that a vaccine could do the same," she said. Read more at Bloomberg and The Guardian. Tim O'Donnell
