First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study involved 36 healthy adults aged 18 to 40 who were given a controlled dose of the Omicron BA.5 virus. The goal was to find a safe dose that causes infection in at least 40% of people, while monitoring side effects. This type of research helps scientists better understand the virus and could speed up development of new vaccines and treatments.
