ATAD1 and malaria: Here we report that vaccination of healthy adult volunteers with ChAd63 and MVA vectors encoding the blood-stage P. falciparum malaria antigens MSP1 and AMA1 induces mBC responses comparable to similar vaccine studies using protein-in-adjuvant vaccines.25 Following CHMI, an mBC response to the 19 kDa C-terminus of MSP1 (MSP119) develops in malaria-naive infectivity control volunteers, whereas responses to both the MSP119 and AMA1 antigens are boosted in previously vaccinated individuals.
