snoop1130 Posted April 1, 2020 Share Posted April 1, 2020 Chinese scientists seeking potential COVID-19 treatment find 'effective' antibodies By Martin Quin Pollard A scientist works in the lab of Linqi Zhang on research into novel coronavirus disease (COVID-19) antibodies for possible use in a drug at Tsinghua University's Research Center for Public Health in Beijing, China, March 30, 2020. REUTERS/Thomas Peter There is currently no proven effective treatment for the disease, which originated in China and is spreading across the world in a pandemic that has infected more than 850,000 and killed 42,000. Zhang Linqi at Tsinghua University in Beijing said a drug made with antibodies like the ones his team have found could be used more effectively than the current approaches, including what he called “borderline” treatment such as plasma. Plasma contains antibodies but is restricted by blood type. In early January, Zhang’s team and a group at the 3rd People’s Hospital in Shenzhen began analysing antibodies from blood taken from recovered COVID-19 patients, isolating 206 monoclonal antibodies which showed what he described as a “strong” ability to bind with the virus’ proteins. They then conducted another test to see if they could actually prevent the virus from entering cells, he told Reuters in an interview. Among the first 20 or so antibodies tested, four were able to block viral entry and of those, two were “exceedingly good” at doing so, Zhang said. The team is now focused on identifying the most powerful antibodies and possibly combining them to mitigate the risk of the new coronavirus mutating. If all goes well, interested developers could mass produce them for testing, first on animals and eventually on humans. The group has partnered with a Sino-U.S. biotech firm, Brii Biosciences, in an effort “to advance multiple candidates for prophylactic and therapeutic intervention”, according to a statement by Brii. “The importance of antibodies has been proven in the world of medicine for decades now,” Zhang said. “They can be used to treat cancer, autoimmune diseases and infectious diseases.” The antibodies are not a vaccine but could potentially be given to at-risk people with the aim of preventing them from contracting COVID-19. Normally it takes around two years for a drug even to get close to approval for use on patients, but the COVID-19 pandemic means things are moving faster, he said, with steps that would previously be taken sequentially now being done in parallel. Zhang, who posted the findings online, hopes the antibodies can be tested on humans in six months. If they are found to be effective in trials, actual use for treatment would take longer. Other experts urge caution. “There’s a number of steps which will now need to be followed before it could be used as a treatment for coronavirus patients,” Hong Kong University infectious disease specialist Ben Cowling said when the finding was described to him by Reuters. “But it’s really exciting to find these potential treatments, and then have a chance to test them out. Because if we can find more candidates, then eventually we’ll have better treatment,” Cowling said. -- © Copyright Reuters 2020-04-01 Follow Thaivisa on LINE for breaking COVID-19 updates 2 Link to comment Share on other sites More sharing options...
doggie1955 Posted April 1, 2020 Share Posted April 1, 2020 A French group has been doing the same testing, and now the Americans started doing the same testing two weeks ago... So far so good! But before they recovered, they where on a treatment plan with PLAQUENIL tablet 200 mg (hydroxychloroquine) and a Z-Pack. Now Germany has done the same treatment plan, and has added a cannabis/hemp oil also. Plasma contains antibodiesis is not new, it's been done before. 2 Link to comment Share on other sites More sharing options...

I don't think what the Chinese are working on is a plan to use plasma from people who have recovered from Covid19.. I know that's what American doctors want to get going on since it can be done right way. The Chinese are looking to duplicate the antibodies found in plasma that will stymie the Covid 19 virus. Ultimately this is a much more powerful and versatile tool than plasma. But it will take longer. In some other thread, a poster included a link to Australian researchers who are aiming at the same goal as the Chinese.

Popular Post Stevemercer Posted April 2, 2020 Popular Post Share Posted April 2, 2020 While all means to a vaccine should be explored, it seems unlikely that a universal vaccine can be developed using antibodies that will effectively stop Covid-19. For example, most of the world's population still gets colds/flu every years. Even those vaccinated still get different strains. There doesn't seem to be an effective vaccine to stop the common cold/flu corona viruses. Hopefully any vaccine can target the most deadly strains. 3 Link to comment Share on other sites More sharing options...

partington Posted April 2, 2020 Share Posted April 2, 2020 8 hours ago, Stevemercer said: While all means to a vaccine should be explored, it seems unlikely that a universal vaccine can be developed using antibodies that will effectively stop Covid-19. Vaccines don't "use" antibodies or contain them. Vaccines contain the disease agent ( deactivated virus, fragments of virus, or DNA coding for fragments of the virus). These cause the body to make its own antibodies against the disease without having to experience or suffer the disease. Many vaccines exist which give near lifetime immunity to the disease: others give much shorter term immunity. Since the SARS-CoV-2 virus seems to be quite stable so far, and not exist in significantly antigenically different strains (unlike the flu viruses) it is quite likely that immunity acquired from a SARS-CoV-2 vaccine will be effective against this virus for a long period. 1 Link to comment Share on other sites More sharing options...

The immunity antibodies give is relatively short lived. So it's great as a treatment and a short term preventative measure. But if you want a long term way to keep the virus in check, then it's vaccines. So no, not only are Bill & Melinda not spitting blood, but I heard they were actually popping open bottles of DP to celebrate this and similar promising developments.
