Hundreds of thousands of second-grade schoolchildren, averaging seven years old, will give the answer next year to the most urgent and immediate question confronting medical scientists: Can the vaccine developed by the University of Pittsburgh's Dr. Jonas E. Salk (TIME, Feb. 9) halt the ravages of polio...
...vaccine, designed to be a true preventive, is made from dead virus by a process developed by the University of Pittsburgh's Dr. Jonas E. Salk (TIME, Feb. 9). Since the first announcement of his work, Dr. Salk said last week, 474 more subjects, both children and adults, have received the vaccine with no ill effects, and in most cases, with a prompt and dramatic increase in the blood-borne antibodies which give protection against polio. Cautious Dr. Salk made no claim that he had found the answer to the perils and paralysis of polio. There may be several...
...University of Pittsburgh's Dr. Jonas E. Salk, of polio-vaccine fame, reported in the A.M.A. Journal that the technique of preparing killed virus in a mineral-oil suspension (instead of water) works well in influenza vaccines also. His research team, which includes Army medics, said the oil vaccine gives protection against flu for two years (twice as long as the water form) or even longer, and against a larger number of flu-virus strains...
While officials of the National Foundation for Infantile Paralysis sat on the edge of their chairs, Virus Expert Jonas E. Salk of the University of Pittsburgh gave out up-to-date details last week of the vaccine (TIME, Feb. 9) which, it is hoped, can defeat polio. Key points in his review: ¶The virus can be readily cultivated in tissues from monkeys' kidneys. This process gives a higher yield than using monkey testicles (on which earlier experiments were made) and is safer than using brain tissues. ¶After the virus has been killed with formaldehyde, it can still...
...Salk, who is only 38, and the four other members of his research team had answered most of the technical questions about a useful polio vaccine. But many practical problems remained. One, Dr. Salk emphasized, was the care that must be taken to insure that no live virus, capable of causing disease, slips in with the dead virus used in a vaccine. Because this slows down a testing program, said Dr. Salk, he has not had time to think about a mass trial for the vaccine. That may come in 1954. and, if successful, wider use in epidemic areas...
