A comparative study of two live measles vaccines in Iran

Abstract

The results of immunization of 523 children from 9 months to over 5 years of age with two attenuated measles vaccines, ‘Denken’ and ‘Biken’, are described. The clinical reactions following vaccination with both vaccines were mild, but Denken vaccine produced more rashes than the Biken vaccine. The serological conversion was satisfactory for both vaccines but a higher titre of neutralizing and haemagglutination-inhibiting antibodies was found in children immunized with Denken vaccine. The incidence of severe reactions or complications was negligible in this trial. The immunity to diphtheria or tetanus was not altered by vaccination with live measles vaccine. © 1970, Cambridge University Press. All rights reserved.
