A possible relation between human pathogenicity of smallpox vaccines and virus growth at elevated temperatures
Published online by Cambridge University Press: 15 May 2009
Summary
Seven smallpox vaccines of known human pathogenicity were tested for their ability to produce pocks on the chick chorioallantois at 39·7° C. Significant differences were found and the more pathogenic strains produced pocks with greater efficiency at 39·7° C. than did strains of average or low pathogenicity.
