No current clinical role for smallpox vaccination; leaves open value of historical success data for research.
SMALLPOX VACCINATION BRI=JSE 285 (27.3%) unsuccessful.The total successes from both vaccinations numbered 920 (92.6%).Multiple pressure gave a higher success rate than the scratch technique in persons previously vaccinated, and the difference between the success rates for the two methods is due to the greater failure of the scratch method in previously vaccinated males.No significant difference for either sex or with either technique was noted among primary vaccinations.Some possible explanations for the difference between the two techniques in previously vaccinated males are discussed.
