The immunogenicity and protective efficacy of four versions of
recombinant C-terminal 19-kDa epidermal growth factor-like region of
the major surface protein 1 (rMSP119) of Plasmodium falciparum was studied in Aotus monkeys. Vaccination
with each of the four rMSP119 constructs elicited high
levels of antibodies to MSP119 but only one construct, the
19-kDa fragment expressed as a secreted fusion protein from
Saccharomyces cerevisiae (yP30P2MSP119), induced a high degree of protective immunity in Aotus
nancymai against lethal P. falciparum challenge.
Protective formulation required Freund's adjuvant; vaccination with
yP30P2MSP119 in six other adjuvants that are suitable for
human use induced lower levels of antibody response and no protection.
These results emphasize the need to continue the search for an adjuvant
that is comparable to Freund's adjuvant in potency and is safe for use
in humans.
