...nail down the vaccine's effectiveness. Last week it announced the encouraging results of a check on the year's first 624 cases in which detailed vaccination histories were available. Of the 4.9 million children under five (the most susceptible age group) who had received no Salk shots, 298 got paralytic polio, for a rate of 6 per 100,000. Of the 10.4 million who had had three or more shots, only 52 got paralytic polio, for a rate of .5 per 100,000 cases. The ratio was almost identical in the next most vulnerable group, aged...
Unless there is a dramatic and unexpected reversal of trends, 1959 will be the worst year for poliomyelitis in the U.S. since 1955, when the Salk vaccine became generally available. With the peak not expected for another month, the U.S. Public Health Service reported last week that polio is almost twice as prevalent this year as last. Latest tallies showed 1,462 cases (956 paralytic) so far in 1959, v. 877 (only 437 paralytic) for the same period in 1958. In the latest week reported, the increase was especially alarming: 257 cases-a 50% jump over the previous week...
...good result of polio's big ill wind was a rush for vaccinations. Ironically, one of the places that needed a scare to get the needles flashing again was Pittsburgh, where Dr. Jonas E. Salk developed the vaccine. Thanks largely to a Pittsburgh Press drive, more than 150,000 shots have been given in a month in community clinics, at an average charge of 75^?. In some areas vaccine supplies were exhausted for a while but soon replaced. So far the problem was only distribution, not a national shortage...
...parotid (salivary) glands. (Dr. Heller's theory: the Gross material had contained two viruses.) Dr. Stewart teamed with the NIH's Dr. Bernice E. Eddy to grow the solid-tumor virus in tissue cultures of monkey kidney cells (as polio virus is grown to make Salk vaccine...
Despite the continuance of polio, Surgeon General Leroy E. Burney of the PHS said last week that the Salk killed-virus vaccine has proved 90% effective. The trouble is that an estimated 40 million Americans in the susceptible undergo age group have not taken the shots...
