COVID test, which deliberately infects young adults, found to be safe

14 Sept 02:51 Key points summarised by AI
  • The world's first "human challenge" trial for COVID-19 safely exposed healthy young adults (18-29) to the virus, with no serious adverse events reported.
  • This groundbreaking study establishes a safe model for future research, enabling the accelerated testing of new vaccines and medicines against COVID-19.
  • Clinical insights revealed symptoms typically emerge two days post-exposure, infectious virus peaks around five days (more abundant in the nose), and lateral flow tests reliably indicate infectiousness.
  • Infected participants experienced only mild-to-moderate, cold-like symptoms, and temporary loss of smell largely resolved within 90 days, confirming the model's safety and tolerability.
