Variables that vary between scenarios^**.

**One variable was varied at a time. In each scenario, the variables not being evaluated were fixed at the reference levels (indicated in bold). ‡The seasonality follows that of Namawala, Tanzania.[68] Each simulation assumes a recurring pattern of the vectoral capacity. †The proportion of infections cleared by the genotypes are set at 100%,100% and 50%. *We investigated the effect of age at dose by simulating a single IPTi dose at varying ages.
