...medical preparation has been launched on its lifesaving career under a more brilliant spotlight than the Salk vaccine against paralytic polio. This very glare has made it harder for some to see certain essential facts-the vaccine is not always effective, and its potency is not assured. Now Dr. Jonas E. Salk (TIME Cover, March 29, 1954) has searchingly reviewed his vaccine's potency and performance. See MEDICINE, Calling the Shots...
Although the Salk vaccine against poliomyelitis has been generally effective -saving hundreds of lives and preventing thousands of cases of paralysis in four years-much of the material used in about 200 million U.S. inoculations has been no good. As a result, an all-out effort to improve the commercially produced vaccine is now being made. Until this succeeds, individuals who have already had three injections should get a fourth...
This was the word last week at a University of Michigan symposium with which the National Foundation launched its 1959 March of Dimes. Vaccinventor Jonas Salk was more frank than ever before in conceding the ineffectiveness of an unspecified proportion of the commercial vaccine released, and contrasting it with the small batches made in his University of Pittsburgh laboratory. Dr. Salk has always stoutly insisted that his handmade vaccine was capable of doing everything expected of it, and among hundreds of children inoculated with it there have been few cases where it failed to "take." Lat since wholesale vaccinations began...
While the Salk vaccine proved to be "60% to 90% effective," polio remained, by shifting targets, a major problem. It used to be primarily a disease of the oft-diapered, well-scrubbed upper-income groups, whose infants were protected against the mild (often undetectable) infections that give immunity against later and more serious attacks. Things were different with the infants of the poor, who lived amid filth, got an infection in their first few months while still protected by passive immunity from inherited antibodies. Now the better-heeled families are dutifully getting Salk shots early and often. The people...
...Salk vaccine shots were so ignored in Detroit this summer that doctors and druggists had to return outdated supplies. Last week, with a growing epidemic, Detroit was the worst polio spot in the U.S. Statistics: 464 current cases (230 paralytic) and 14 deaths, against a total of 163 cases and two deaths by the same week last year. Well over half (279) of the victims were Negroes, mainly children under 15, centered in the city's low-income Negro sections. This week they could plead neither ignorance nor poverty. Polio was suddenly Detroit's best-publicized word...
