From the abstract: "The rapid spread of antimalarial drug resistance currently compounds this grim picture. In this paper, we review the history of antimalarial drug resistance and the methods for monitoring it and assess the current magnitude and burden of parasite resistance to two commonly used drugs: chloroquine and sulfadoxine-pyrimethamine.

From the abstract: "We show that informational constraints play an important role in the household decision to seek vaccination, and moreover, that learning about the efficacy of vaccinations only through empirical observation may be hard even in environments with variation in vaccination and the high incidence of vaccine-preventable diseases. We argue that when learning about vaccination is inefficient, households use concurrent interventions with easily observable outcomes to evaluate the veracity of a provider's claim regarding preventive care.
