Members of Congress have proposed a joint resolution which would express the gratitude of the nation to three University scientists whose work contributed to the development of the Salk polio vaccine...
Although the two resolutions are not identical, both state that Enders, Weller, and Robbins paved the way for the final development of the vaccine by Dr. Jonas Salk when, in 1949, they discovered that the virus can multiply in tissue from primates...
...Nov.1). This amount was to be given free to some 9,000,000 (children and pregnant women) most threatened by polio. At the same time, the manufacturing companies also decided to make an identical amount of vaccine on their own account, to be sold commercially. But last week, Dr. Salk upset everybody's calculations by reporting that it is better not to give all three shots within five weeks. More effective to build up immunity, Dr. Salk has found, will be two shots this spring, within a month, and a third after at least seven months. As a result...
...pharmaceutical firms* are now producing Salk vaccine or hurrying to get into production. The vaccine works on a principle that has already provided protection against such traditional plagues as smallpox and yellow fever. When they attack human beings or other mammals, most viruses stimulate the invaded system to manufacture tiny protein particles "called antibodies. If the system under assault does not have enough of these antibodies, or cannot manufacture them fast enough, the victim may die, or, with polio, suffer permanent crippling. Polio virus is unusual in that there are three main types. All can cause paralysis, but one type...
Never before in history had a medical development been big, instantaneous news over a large part of the world. Such a momentous item as Fleming's penicillin moldered for years in musty libraries before laymen heard of it. Last week's report on the Salk vaccine was good for banner headlines everywhere, and was covered by the press as massively as the end of a major war-which it was. Ironically, poliomyelitis has always been a relatively uncommon disease with a comparatively low death rate.* Polio is actually less of a public-health problem than rheumatic fever...
