Allen Roses, worldwide vice-president of genetics at GlaxoSmithKline (GSK), said fewer than half of the patients prescribed some of the most expensive drugs actually derived any benefit from them.
The findings by a team of influenza and immune system experts suggest new and better ways to fight viruses -- especially new pandemic strains that emerge and spread before a vaccine can be formulated.
These survivors, now aged 91 to 101, all lived through the pandemic as children.
Their immune systems still carry a memory of that virus and can produce proteins called antibodies that kill the 1918 flu strain with surprising efficiency, the researchers report in the journal Nature.
"It was very surprising that these subjects would still have cells floating in their blood so long afterward," said Dr. James Crowe of Vanderbilt University in Tennessee, who helped lead the study.
NIMR scientists have solved an 85-year old riddle by determining the structure of the Haemagglutinin (HA) of the flu virus which jumped from birds to humans in 1918 killing more than 20 million people worldwide. The work published today (5 February) in the online version of the journal Science will contribute to understanding of flu viruses and their transmission from birds to humans.
The first step in infection by flu viruses is their attachment to the cells in which they will replicate themselves. Attachment involves the Haemagglutinins spike-like molecules that project from the viruses and bind to particular receptors on the surface of cells in the body.
X-ray crystallography was used to determine the three-dimensional structure of the HA of the 1918 virus based on RNA sequences obtained in the USA from pathological specimens preserved since 1918.

Environmental groups say the chemical, bisphenol A, can hurt children and animals. But the FDA and European regulators, as well as the plastics industry, say it is safe.
The National Toxicology Program, part of the U.S. government's National Institutes of Health, has issued a draft report expressing concern that bisphenol A could cause neural and behavioral problems in fetuses, infants and children.
The FDA said its meeting would focus on this.
On a typical day, you might see ads featuring a naked woman's body tempting viewers to buy an electronic organizer, partially exposed women's breasts being used to sell fishing line, and a woman's rear -- wearing only a thong -- being used to pitch a new running shoe. Meanwhile, on every newsstand, impossibly slim (and digitally airbrushed) cover "girls" adorn a slew of magazines. With each image, you're hit with a simple, subliminal message: Girls' and women's bodies are objects for others to visually consume.
The study of students at one Ohio university found that students who scored high on measures of courage, empathy and honesty were less likely than others to report their cheating in the past - or intending to cheat in the future.
