JERUSALEM (Oct. 7)
Vaccines with living viruses, instead of with dead organisms as in the Salk vaccines, will be introduced in Israel’s anti-polio inoculations next year, Dr. A. Goldbloom, Director of the Government Medical Laboratories in Jaffa, reported today to the Israel Pediatric Society conference. He said such vaccines, in which the virus is weakened but not killed, was being used in the Belgian Congo and on a limited scale in the United States.
At an earlier session, the pediatricians heard a report that there had been a 1,000 percent increase in polio incidence this year compared with last year when mass Salk vaccination had produced a sharp drop in polio cases in Israel. The delegates were told that while the polio figures for this year were dramatically lower than before the introduction of Salk vaccinations, apparently a new strain of polio virus, more resistant to the Salk vaccine, had appeared.
