Abstract
IN a recent paper (Public Health Rep., 58, 1121; 1943), Selwyn D. Collins, head statistician, and Clara Councill assistant statistician of the United States Public Health Service, record their study of immunization against diphtheria, smallpox, scarlet fever and typhoid fever based on a canvas of 213,931 households in 23 cities of 100,000 or more inhabitants. Their conclusions are as follows. Immunizations against scarlet fever and typhoid fever are negligible compared with those against diphtheria and smallpox. In the pre-school age immunizations against diphtheria are more frequent than vaccinations against small-pox, but after five years the reverse is true. There was considerable geographical variation in the extent of immunization against the diseases. In the north, for example, the percentages of native, foreign and coloured children of specific ages immunized against diphtheria are approximately the same, while in the south a higher percentage of the native whites is immunized than of the foreign 'whites or coloured.
