...Cutter question seemed finally answered. It was a rash of polio cases following use of Cutter vaccine that had first halted the vaccination program. For weeks, experts have broadly suggested that some live virus must have slipped through the killing and testing process in the manufacture of the Cutter product. Last week, for the first time, a virologist flatly asserted that he had found live virus in Cutter specimens. He was Dr. Louis P. Gebhardt, professor of bacteriology and director of the polio research laboratory at the University of Utah. The chilling thought, of course, was that what happened...
...sweep up some of the dust kicked up by the polio row in his Department of Health. Education and Welfare, President Eisenhower had picked Nelson Rockefeller. Under Secretary in the Department and a presidential troubleshooter, Rockefeller drafted a formal progress report on the vaccine situation, which Ike released last week. Full of the obvious lessons from the vaccine mix-up ("From the delay science has gained new knowledge, new safeguards"), the report carried one bit of near-news: enough vaccine to complete the two free shots for the first-and second-graders, run by the National Foundation for Infantile Paralysis...
...specific reason has yet been found to explain why two lots of vaccine made by California's Cutter Laboratories should have touched off polio infections in so many cases (69 at week's end), but Dr. Sebrell went...
...Before single-strain vaccines (representing each of the three main types of polio virus) are mixed to form the triple-threat end product, there must be more tests, using much larger volumes of material. Formerly, one-tenth of 1% of each strain was taken for testing; now, a minimum of 500 cc. must be used-a tenfold increase for a firm making vaccine in lots of 150,000 cc., and probably some increase for all manufacturers...
...original "safe" vaccine had been followed by 113 cases of polio among the vaccinated. Last week an additional ten were among Cutter subjects. But because four full weeks had passed since Cutter inoculations were stopped, and the incubation period for polio is rarely more than 31 days, it seemed more likely that in the new Cutter cases the trouble was not defective vaccine, but the absence of a second shot in time to prevent a natural polio infection...
