...Michigan, mainly in Detroit), against 96 for the same week of 1957. In the week ending Aug. 30 the total fell only slightly to 126 cases, against 76 last year. Warned Surgeon General Leroy E. Burney: "The tragic fact is that many of the cases could have been prevented. Salk vaccine gives 70% to 90% protection against polio, but about 40 million Americans in the susceptible under-40 age group have not yet been vaccinated...
...vaccine against paralytic polio would be one containing live virus -it is cheaper to give, easier to take (by mouth) and should be more potent. But U.S. health authorities are fearful that some virus might prove to be not only live but virulent. They play it safe with the Salk vaccine, in which the virus is killed with formaldehyde. Now, from darkest Africa, comes the report of a trial in which a quarter-million people have been given a live-virus vaccine made in the U.S. It appears to have been completely safe, almost 100% effective...
...National Foundation for Infantile Paralysis announced last week a change of name and a raising of its sights against far commoner ills than polio. Henceforth to be called simply the National Foundation, the aggressive organization that spent $34 million on the research that produced (among other gains) the Salk vaccine * will turn its attention to two other cripplers: the rheumatic diseases and defects present in children at birth...
...Some 70 million Americans have now been vaccinated (50 million with three shots); since some do not respond to the vaccine and develop no immunity, there is a widening pool of vaccinated subjects who may still get paralytic polio. But why do these people not respond? Vaccinventor Jonas E. Salk has spent most of the summer studying non-responders. Last week all he would say was: "The essential point is that the proportion of individuals who do not respond is influenced by vaccine potency." Last summer there was considerable evidence (TIME, July 15, 1957) that some of the vaccine, whose...
...word last week that it will soon make "the first announcement of our plans" for a new program-now that victory over paralytic poliomyelitis has been substantially achieved. The plans, said O'Connor, "have been many years in the making." He might have added that ever since the Salk vaccine, developed with N.F.I.P. funds, was recognized as a weapon capable of preventing the worst ravages of polio, the roar of speculation about what the foundation would do next has been almost loud enough to drown out the annual March of Dimes (354 million this year...
