This paper describes a large-scale, feminist-informed research prioritization exercise that engaged over 900 participants (primarily from low/middle-income countries) to identify the top 21 research questions on gender and COVID-19. The highest-priority questions focused on including pregnant and lactating women in clinical trials, improving sex-disaggregated data systems, and addressing gender-based violence and vaccine uptake through an intersectional lens. The findings underscore that basic gender-inclusive practices in science and health systems remain unaddressed, while also highlighting frontier issues like mental health impacts and algorithmic bias.
