ReviewRecent progress in the development of plant derived vaccines.
Recombinant subunit vaccines have been with us for the last 30 years and they provide us with the unique opportunity to choose from the many available production systems that can be used for recombinant protein expression. Plants have become an attractive production platform for recombinant biopharmaceuticals and vaccines have been at the forefront of this new and expanding industry sector. The particular advantages of plant-based vaccines in terms of cost, safety and scalability are discussed in the light of recent successful clinical trials and the likely impact of plant systems on the vaccine industry is evaluated.

Smallpox, eradicated as a cause of natural disease through an intensive global effort in the later part of the 20th Century, has resurfaced as a possible agent of bioterrorism. For this reason, there is renewed interest in smallpox vaccines. ⋯ This has led to a surge of recent research into newer-generation smallpox vaccines with improved safety profiles and retained efficacy. This article will review the history of smallpox vaccines, assess the status of newer-generation vaccines and examine the overall risk-versus-benefit profile of smallpox vaccination.
