Cross-reactive and protective epitopes of CS

摘要

Synthetic peptides containing non-repeating epitopes of circumsporozoite derived protein antigen and which are substantially shorter in length than the intact antigen are disclosed. The peptides when administered to a host raise antibodies in that host that will bind to the circumsporozoite antigen on the parasite. Vaccines based upon these peptides, as well as means of raising antibodies to circumsporozoite antigens using the synthetic peptides are also disclosed.
