RESULTS OF SMALLPOX REVACCINATION IN ADULTS IN 1957, 1960 AND 1962
Abstract
Positive results from revaccinating adult persons using smallpox detritus in 1957, 1960, and 1962 were obtained from, respectively, 78, 46, and 84% of those inoculated. The influenza epidemic evidently cannot be the reason for the high inoculability upon the last revaccination, since in the same epidemiological situation inoculability was half as high before the preceding revaccination. The high inoculability upon revaccination in 1962 can be explained by the higher virulence of the vaccine. The inoculability of the vaccine depended also on the results of the preceding revaccination: the smallest number of positive skin reactions (8%) on repeated reimmunization was observed for inoculated persons who had evidenced strongly positive postvaccinal reaction the last time.
