Vaccine development costs: a review.

The cost of drug development is commonly cited between US$800 and US$1.8 billion. A similar statistic for vaccines is yet to be estimated, and it is unclear whether the cost of vaccines is similar to drug development. Financial and regulatory policy significantly impacts the extent and cost of pharmaceutical development, and as such it is important that governments should be informed about the costs of developing vaccines. The purpose of this paper is to review the concept of drug and vaccine R&D costs, to review the associated literature and to relate these findings to the area of vaccine industry's financial and regulatory policy.
