The possibility of drying of the poliomyelitis virus is of great significance for obtaining not only the standard antigen for the diagnostic investigations, but also the stable live vaccine against poliomyelitis from nonpathogenic strains, one of which (type 11P-712[5]) was employed in the present work. The survival of the poliomyelitis virus during the process of drying of the culture fluid media was studied. Positive results were obtained. When drying the culture in the presence of egg yolk and saccharose the titer of the dry preparations was on the average lower than in the initial material by 1 point of ogarythim, viz., the viability reached 10%. A definite relationship between the survival of the virus and the concentration of the protective medium was revealed.
