Inactivation of Poliomyelitis Virus for the Preparation of Vaccines

Abstract

Summary An extensive series of experiments designed to establish the practicality of combining formaldehyde inactivation with ultraviolet irradiation as a method for the inactivation of poliomyelitis virus for the production of vaccines has been reviewed. The actual use of the combination method is illustrated by safety, stability and potency test data obtained in a series of experimental vaccines. These vaccines were also subjected to trial in humans. The objective has been to introduce and illustrate the feasibility of producing virus vaccines according to standards (11), particularly poliomyelitis, by the use of a combination of chemical (formaldehyde) and physical (ultraviolet) methods of inactivation.
