Desired Characteristics
Effective cancer vaccines must resolve several challenges. Cancer vaccines seek to target an antigen specific to the tumor and distinct from self-proteins. Selection of the appropriate adjuvant, molecules that activate antigen-presenting cells to stimulate immune responses, is required. At the present time, only Bacillus Calmette-Guérin (BCG), aluminum-based salts and a squalene-oil-water emulsion are approved worldwide for clinical use. The effective vaccine also should seek to provide longterm memory to prevent tumor recurrence. Some scientists believe that for total tumor elimination, both the innate and adaptive immune systems should be activated.

Famous quotes containing the word desired:
“Increasingly in recent times we have come first to identify the remedy that is most agreeable, most convenient, most in accord with major pecuniary or political interest, the one that reflects our available faculty for action; then we move from the remedy so available or desired back to a cause to which that remedy is relevant.”
—John Kenneth Galbraith (b. 1908)
