During the years 1940-1955, the rate of decline in the U.S. death rate accelerated from 2% per year to 8% per year, then returned to the historical rate of 2% per year. The dramatic decline in the immediate post-war years has been attributed to the rapid development of new treatments and vaccines for infectious disease that occurred during these years. Vaccine development continued to accelerate, with the most notable achievement of the period being Jonas Salk's 1954 development of the polio vaccine under the funding of the non-profit National Foundation for Infantile Paralysis. The vaccine process was never patented, but was instead given to pharmaceutical companies to manufacture as a low-cost generic. In 1960 Maurice Hilleman of Merck Sharp & Dohme identified the SV40 virus, which was later shown to cause tumors in many mammalian species. It was later determined that SV40 was present as a contaminant in polio vaccine lots that had been administered to 90% of the children in the United States. The contamination appears to have originated both in the original cell stock and in monkey tissue used for production. In 2004 the United States Cancer Institute announced that it had concluded that SV40 is not associated with cancer in people.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who identified the SV40 virus?
Ah, so.. Maurice Hilleman

Jehovah's Witnesses refuse blood transfusions, which they consider a violation of God's law based on their interpretation of Acts 15:28, 29 and other scriptures. Since 1961 the willing acceptance of a blood transfusion by an unrepentant member has been grounds for expulsion from the religion. Members are directed to refuse blood transfusions, even in "a life-or-death situation". Jehovah's Witnesses accept non-blood alternatives and other medical procedures in lieu of blood transfusions, and their literature provides information about non-blood medical procedures.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is one of the Protestant religions who don't see blood transfusions as a big deal?
Ah, so.. unanswerable

The trip was intended to soften the strong isolationist tendencies among the North American public with regard to the developing tensions in Europe. Although the aim of the tour was mainly political, to shore up Atlantic support for the United Kingdom in any future war, the King and Queen were enthusiastically received by the public. The fear that George would be compared unfavourably to his predecessor, Edward VIII, was dispelled. They visited the 1939 New York World's Fair and stayed with President Franklin D. Roosevelt at the White House and at his private estate at Hyde Park, New York. A strong bond of friendship was forged between the King and Queen and the President during the tour, which had major significance in the relations between the United States and the United Kingdom through the ensuing war years.

Ah, so..
