Influence of high and low therapeutic or prophylactic efficacy on parasite burden in primigravidae in high transmission settings. (A) Parasite prevalence in primigravidae (PG) and multigravidae (MG) in unprotected pregnancies (from [2]). The fall in parasite prevalence after four months gestation corresponds to the decline observed if untreated and is related to the development of parity-specific immunity; (B) High therapeutic (100%) and low prophylactic efficacy (≤50%) with two dose SP-IPTp intermittent preventive treatment; (C) High therapeutic (100%) and high prophylactic efficacy (100%); (D) Low therapeutic (≤50%) and low prophylactic efficacy (≤50%).
