Measles Vaccination. I. Serologic Responses to Vaccination with Inactivated Vaccine

Abstract

Following a single vaccination, serologically-immune children showed sharp rises in antibody titers which declined shortly thereafter. Serologic conversion was accomplished in susceptible children following 1, 2, or 3 injections at monthly intervals. These conversion antibody titers declined at a slow rate but were significantly elevated following a single revaccination some months later. There was no opportunity to evaluate the protective value of these antibody demonstrations.
