Brief Summary:
This is a Phase Ib multi-stage Plasmodium falciparum malaria vaccine study to assess the safety and immunogenicity of the blood-stage vaccine candidate RH5.2 virus-like particle (VLP) in Matrix-MTM and the pre-erythrocytic stage vaccine candidate R21 in Matrix-MTM, both alone and in combination, in adults and infants in the Gambia
Detailed Description:
A total of 96 volunteers will be enrolled. Adults (18-45 years) will be enrolled into groups 3 -5. Infants (5 -17 months) will be enrolled into groups 1-2 and groups 6-9. All volunteers will be given 3 doses 50 µg of Matrix-M in combination with RH5.2 VLP and/or R21 via intramuscular (IM) injection in the deltoid region of the non-dominant arm for adults and anterolateral thigh for infants. The first 2 doses will be given at months 0 and 1. Groups 2-6 and group 8 will be given the third dose at month 2, and groups 1, 7 and 9 will be given the third dose at month 6.
