Abstract
The invention concerns the stabilization of a vaccine composition maintained in liquid state by the use of high molecular weight polyvinylpyrrolidone, hence eliminating the use of albumen. The invention is of particular interest for vaccine compositions comprising attenuated live viruses such as oral vaccine against poliomyelitis.
