Observational analysis shows full prevention of blood stage infections in vaccinees, indicating vaccine efficacy.

Complete prevention of blood stage infections resulted from chemo-attenuation using atovaquone–proguanil.
In a clinical trial, both doses of PfSPZ were effective against blood stage infections after vaccination.
Comparative analysis showed protection was linked to antibodies for specific liver-stage antigens and not the major protein.
The findings suggest that using a single-dose of atovaquone–proguanil may simplify malaria prevention regimens.

Borrmann et al. (2025) studied this question.
