Six months after catching the coronavirus, a 69-year-old Russian virologist and researcher exposed himself to patients infected with Covid-19 without any protection to see how his immune system would respond.
A former researcher at the Vector Centre of Virology and Biotechnology in Koltsovo, Novosibirsk, Alexander Chepurnov first caught Covid-19 at the end of February 2020. He was on a skiing holiday in France when he started feeling unwell, with a high fever, sharp chest pain and a complete loss of his sense of smell. There was no way to get a coronavirus test in Europe at the time, so he returned home to Novosibirsk, where he was quickly diagnosed with double pneumonia. He was lucky enough to recover, and a month later an antibody test confirmed that he had been infected with the new virus.
