title: Virus vaccines: principles and prospects.
abstract: The present status of vaccination for controlling viral diseases is reviewed, and the needs and directions for future investigations are discussed. A survey of viral vaccines now in use has shown that knowledge about the viral agents and about the hosts' responses to infection was essential for their development. The steps needed to demonstrate the efficacy and safety of a viral vaccine are summarized; the final requirement for a successful vaccine is that it be administered in proper dosage and potency to the target populations. After general remarks on the proper use of current vaccines there follows an overview of various developments in creating new vaccines, along with the predicted time-frames for their coming into general use. Topics considered include vaccines to be administered locally at the portal of entry, subunit vaccines, viruses attenuated by genetic manipulation, use of viral vectors, vaccines developed by means of recombinant DNA, synthetic peptides, and anti-idiotype vaccines, as well as new vaccines being developed by more conventional methods.
