The PMI VectorLink Project

Objectives

The primary objectives of this project were to:

  1. Direct implementation of and/or technical assistance for implementation of IRS and other proven, life-saving vector control interventions utilizing an integrated approach to malaria vector control programming;
  2. Support entomological and epidemiological monitoring and provide technical support for strategic decision making and deployment of vector control interventions for malaria control;
  3. Procure insecticides for IRS and support the delivery and storage of IRS and other malaria vector control products; and
  4. Support innovation in vector control interventions for malaria control, including piloting of promising novel tools or approaches that have received World Health Organization (WHO) recommendation for malaria control or promising products with a strong evidence base to be considered by WHO for recommendation.
Rationale and Abstract

Malaria, one of the world’s deadliest diseases, is transmitted by one of the world’s smallest insects—the mosquito. Bites from malaria-carrying mosquitoes resulted in 247 million cases of malaria globally in 2021, with 619,000 people dying from the disease. To reduce malaria transmission and ensure that fewer people become sick or die from this illness, vector control—activities that prevent mosquitoes from spreading the disease—is essential.

The U.S. President’s Malaria Initiative (PMI) has protected millions of people from malaria since 2005, through malaria prevention and vector control efforts. Between 2017 and 2023, the PMI VectorLink Project  worked across 25 countries in sub-Saharan Africa as well as Cambodia and Colombia, to help national malaria programs plan and implement lifesaving, cost-effective, evidence-based, and sustainable malaria control activities, with the overall goal of reducing malaria cases and deaths.

Strengthening Local Capacity: The PMI VectorLink Project focused on enabling local partners to implement malaria programs with minimal support. Through integrating data management systems, shifting implementation of spray campaigns to national programs, and providing research institutions with the skills and equipment to conduct key analyses, countries are one step closer to achieving local sustainability in their malaria control interventions. 

Reaching the Unreached: People living far from health centers, who are generally less likely to access any kind of health services. Refugee populations, who are often living in tented camps and may not be included in national malaria interventions. People living with disabilities, another group often overlooked when planning malaria control activities.

PMI VectorLink made concerted efforts to reach these unreached groups, in line with  PMI’s strategy  to achieve and maintain coverage of high-quality interventions that reach remote, rural, and other populations at high risk for malaria that are underserved by health services.

Keeping Malaria Services Resilient: From 2020 through 2022, the COVID-19 pandemic caused widespread disruptions in malaria services, but these services were still needed. Separately, the increasing spread of  Anopheles stephensi , a mosquito that has come to Africa from Asia and exhibits different behavior from other malaria-transmitting mosquitoes on the continent, is also jeopardizing the progress made so far in malaria prevention, as is mosquitoes’ increasing resistance to commonly-used insecticides. 

PMI VectorLink and partners successfully adapted in the face of all these disruptions. They made changes to existing interventions to mitigate the risk of COVID-19 transmission, so that families and communities would be protected from malaria even during the pandemic. They supported extensive mosquito monitoring, so countries could determine if the Anopheles stephensi mosquito had reached their communities, and they continued to help countries conduct critical insecticide resistance testing, which informs decision-making on the best way to control mosquitoes.

Innovate and Lead: Three ways are showing promise:

  • Using solar power to support more environmentally sustainable operations;
  • Using drones to spray larvicide, an insecticide that targets mosquito larvae;
  • Training community members to collect mosquitoes when trained entomologists are not available.
