Ninety years after the sweeping destruction of the 1918 flu pandemic, researchers at Monroe Carell Jr. Children’s Hospital at Vanderbilt have recovered antibodies to the virus – from elderly survivors of the original outbreak.
In addition to revealing the surprisingly long-lasting immunity to such viruses, these antibodies could be effective treatments to have on hand if another virus similar to the 1918 flu breaks out in the future.

For millennia, humans and viruses have been locked in an evolutionary back-and-forth — one changes to outsmart the other, prompting the second to change and outsmart the first. With retroviruses, which work by inserting themselves into their host’s DNA, the evidence remains in our genes. Last year, researchers at Rockefeller University and the Aaron Diamond AIDS Research Center brought an ancient retrovirus back to life and showed it could reproduce and infect human cells. Now, the same scientists have looked at the human side of the story and found evidence that our ancestors fought back against that virus with a defense mechanism our bodies still use today.
