The last sentence of the fourth paragraph of the letter from Albert B. Sabin that appeared in the 8 March issue (p. 1161) was incorrectly printed. It should have read, "It is well known that polio and other enteroviruses can multiply in the intestinal tract in the presence of antibodies in the blood."
