Summary

This study aims to measure how well the VLA1553 vaccine prevents chikungunya virus disease in real-world conditions in Brazil. Researchers will compare about 1,200 people who develop chikungunya-like symptoms, checking if vaccinated individuals are less likely to test positive for the virus. The study uses existing health records from Brazilian government systems to track outcomes after people receive the single-dose vaccine.
