Abstract
The present invention discloses an attenuated smallpox vaccine strain exhibiting antibody production similar to conventional strains but without postvaccinal side effects. The vaccine is prepared by attenuating a Lister strain of a vaccinia virus by cell culture and selecting a suitable strain therefrom showing relatively small and uniform pocks on the chorioallantoic membrane of an embryonated egg.
