A patient receives a dose of the COVID-19 vaccine in Nigeria

As COVID-19 vaccination ramps up worldwide, understanding factors that may lead people in low- and middle-income countries (LMICs) to reject COVID-19 vaccination is of global concern, as lags in vaccination could facilitate global spread of virus variants. Researchers surveyed nearly 45,000 individuals in 10 LMICs, the United States, and Russia between June 2020 and January 2021on vaccine acceptance and trusted sources for vaccination advice.

As of January 2021, COVID-19 has infected approximately 85.2 million people and killed more than 1.84 million people worldwide. Given the importance of individual behavior change in containing the spread of a pandemic, individuals must learn, trust, and apply various recommended health behaviors. In Ghana, researchers are measuring the impact of a quiz-style information strategy on people’s learning and adherence to COVID-19 health protocols.

A child is given deworming medicine in Kenya

Intestinal helminths—including hookworm, roundworm, whipworm, and schistosomiasis—infect more than one in four people worldwide. Researchers evaluated the short-run impacts of a mass school-based deworming program in western Kenya, and found that deworming substantially improved health and school participation of treated children, as well as of untreated children in treatment schools and children in neighboring schools.
