title: Preliminary results on the use of human diploid fibroblasts for inactivated polio virus vaccine production.
abstract: Human diploid fibroblast strains WI-38 and MRC 5 can be routinely grown in Eagles medium to densities between 2x10(5) and 1x10(5) cells/cm2. Polio virus type 1 grew to higher titers in WI-38 than MRC 5; types 2 and 3 grew equally well in both strains. After inactivation with 5 mM formaldehyde at 30 degrees C immunogenicity values were obtained which compared favourably with those obtained from monkey kidney preparations.
