We are unlikely, with current technologies, to have sufficient pandemic influenza vaccine ready in time to impact the first wave of the next pandemic. Emerging data show that prior immunization with an immunologically distinct hemagglutinin of the same subtype offers the potential to "prime" recipients for rapid protection with a booster dose, years later, of a vaccine then manufactured to match the pandemic strain. This article proposes making prepandemic priming vaccine(s) available for voluntary use, particularly to those at high risk of early occupational exposure, such as first responders and healthcare workers, and to others maintaining critical infrastructure. In addition to providing faster protection and potentially reducing social disruption, being able, early in a pandemic, to immunize those who had received prepandemic vaccine with one dose of the pandemic vaccine, rather than the 2 doses typically required, would reduce the total doses of pandemic vaccine then needed, extending vaccine supplies.

Owing to increasing sulfadoxine-pyrimethamine (SP) resistance in sub-Saharan Africa, monitoring the effectiveness of intermittent preventive therapy in pregnancy (IPTp) with SP is crucial. ⋯ The efficacy of SP to clear peripheral parasites and prevent new infections during pregnancy is compromised in areas with >90% prevalence of Pfdhps-K540E. Nevertheless, in these high-resistance areas, IPTp-SP use remains associated with increases in birth weight and maternal hemoglobin. The effectiveness of IPTp in eastern and southern Africa is threatened by further increases in SP resistance and reinforces the need to evaluate alternative drugs and strategies for the control of malaria in pregnancy.

Randomized Controlled Trial
Efficacy, Safety, and Pharmacokinetics of Coadministered Diethylcarbamazine, Albendazole, and Ivermectin for Treatment of Bancroftian Filariasis.
Available treatments for lymphatic filariasis (LF) are limited in their longterm clearance of microfilaria from the blood. The safety and efficacy of a single-dose triple-drug therapy of the antifilarial drugs diethylcarbamazine (DEC), ivermectin (IVM), and albendazole (ALB) for LF are unknown. ⋯ NCT01975441.
