BUFFALO, N.Y. – A 92-year-old woman who survived the Spanish flu in 1918 has given 10 vials of her blood to medical researchers who are trying to develop more effective vaccines against bird flu. Dorothy Horsch was in kindergarten when she contracted the illness, which killed 20 million to 40 million people worldwide. “My mother and father and sister and I, all four of us had it, and all four of us survived,” she said Friday. “That was a miracle.” “All we did was lay in bed.

The family eventually recovered, helped by twice-daily house calls from their doctor. Horsch’s blood will be part of a catalog of blood and bone marrow samples being compiled by Sea Lane Biotechnologies, a Menlo Park, Calif., company that hopes to track changes in the virus that might help develop better vaccines. “We’re looking at the different human responses to the various flus over the course of history,” said Michael Horowitz, general counsel for the company.
