Researchers want to understand why COVID-19 affects people differently in Malawi compared to Western countries. They're enrolling people who have COVID-19 symptoms, their household members, and people receiving vaccines to study how their immune systems respond to infection or vaccination. By following participants for up to 18 months and collecting blood samples regularly, they hope to learn whether certain conditions common in Malawi—like malaria and intestinal parasites—might protect some people from severe COVID-19 or affect how long vaccine protection lasts.
Researchers have noticed that COVID-19 and vaccine responses may work differently in Malawi than in other parts of the world. This study aims to discover whether common health conditions in the region affect how people's bodies respond to the virus and vaccines, which could help doctors better protect people in Malawi and similar communities.

If you join this study, you'll visit a clinic multiple times over 18 months. At your first visit, researchers will collect blood and stool samples and test you for COVID-19 if needed. You'll return for follow-up visits at 15 days, 1 month, 3 months, 6 months, 9 months, and 15 months, with blood draws at most visits. If you're in the vaccine group, you'll receive an AstraZeneca or Johnson & Johnson COVID vaccine during the study. Researchers will track whether you get infected, how long antibodies stay in your blood, and how your immune system responds over time.
