Peptide Vaccines for Malaria

Obtaining a highly effective malaria vaccine is a worldwide priority. The first approach aimed at obtaining a malarial vaccine using synthetic peptides was a polymeric chimeric molecule named SPf66, which conferred limited protective efficacy in Aotus monkeys and in large human field-trials. Our eff...
