This overview of malaria vaccine research focuses on potential vaccines that are in, or expected to enter, clinical trials by the end of 2005. Reviewing both published and unpublished findings, the article categorises different types of vaccines currently in development according to the stage of the malaria parasite life cycle they target. The article assumes knowledge of vaccine terminology, but presents a useful overview, including a summary table, of the status of different vaccine candidates. It also describes growing optimism in the field owing to new funding from private-public partnerships, including new North-South collaborations.
