Abstract

Disclosed is a method of making a malaria vaccine, the method comprising stably transforming a plant by inserting into its plastid genome a nucleic acid sequence encoding and operable to constitutively express a malaria antigenic polypeptide selected from AMA-1, MSP-1 or both; harvesting the stably transformed plant in whole or in part; purifying the expressed malaria antigenic polypeptide from the harvested plant; and packaging the purified antigenic polypeptide under sterile conditions in an amount for a predetermined dosage. Also disclosed is an oral vaccine effective in raising malaria antibodies in a susceptible host, the vaccine comprising leaf material from an edible plant containing plastids stably transformed to constitutively express a fusion polypeptide consisting essentially of cholera toxin B subunit and a malaria antigenic polypeptide selected from AMA-1, MSP-1 or both.
