Medical News Today -- Scientists in the US recovered antibodies to the 1918 flu virus from elderly survivors of the pandemic, used them to create cell lines of monoclonal antibodies and then showed they were still potent by injecting them into infected mice that survived, whereas the controls did not. The researchers believe the antibodies could help develop effective treatments to use in case a similar virus breaks out again, and the technology could help develop antibodies against other viruses like HIV.
