ANN ARBOR, Mich., April 12.—<U.R>—1The Salk anti polio vaccine today was pronounced safe and effective. The long-awaited results, hailed immediately by the American Medical Assn. as “one of the greatest events in the history of medicine,” showed the vaccine was 80 to 90 per cent effective. “The vaccine works.” Those were the first words announcing the results of a thoroughly scientific evaluation of last spring's mass testing among more than 1,800,000 children. Among the 460,000 children who actually received the vaccine, only one died. This child succumbed after a tonsillectomy which was performed two days after he received the second in a series pf three anti-polio shots. Dr. Thomas Francis Jr., professor of immunology of the University of Michigan, who directed the study of the results, made his momentous 113-page report at a specially invoked scientific meeting. Simultaneously, Dr. Jonas E. Salk, creator of the vaccine, revealed at the meeting that 13 million more children than had been anticipated will be able to receive the anti polio vaccine before this year s polio season begins.
