Imperial’s human challenge study helps explain why some people don’t get COVID
New analysis based on Imperial's COVID-19 human challenge study has helped to uncover how some people avoid getting sick. Researchers have found that people who are able to fend off the SARS-CoV-2 virus have unique immune responses which help them to avoid sustained infection. The findings , which are based on samples obtained from the Imperial-led COVID-19 human challenge study, suggest that a localised immune response in the lining of the nose enables individuals to identify the virus and stop it from gaining a foothold to cause infection.
