The antigenic activity of some poliomyelitis vaccines used in the United Kingdom in 1958

Abstract
The potency in man of eight different commercial vaccines and an experimental vaccine, as judged by the antibody response after the primary course of two injections and after a booster dose 9–12 months later, was compared. All the vaccines produced good responses to Types 2 and 3 but some were less satisfactory for Type 1. The relation of potency to protection in man is discussed and the use of one of the vaccines as a minimum standard for this country is suggested.
