Vaccination with Attenuated Measles-Virus Vaccine

Abstract

The immunological efficacy and the absence of communicability of live attenuated measles-virus vaccine in children has been described by Katz and Enders¹and by others^2-10Since immunity to natural measles infection shortly after vaccination has also been reported,^3,4the final acceptance of this vaccine for routine pediatric immunization will presumably depend on the persistence of the immunity conferred and on the severity of reactions to the vaccination. The main purpose of the study undertaken here has been to gain further information regarding the reactions caused by a subcutaneously inoculated attenuated measles-virus vaccine prepared from the chick-embryo-adapted Edmonston strain in institutionalized children and the effect of γ-globulin on such reactions. In addition, the serological response to vaccination was tested by complement fixation (CF) and hemagglutination inhibition (HI) techniques. The full report of this study will be published elsewhere.¹¹ Material and Methods Design and Operation of Study.—The
