Professor Francis Collins, the Christian geneticist who famously led the ‘human genome project’, has said he is hopeful about developing a successful vaccine to protect people against Covid-19. He has recently been asked to join the White House coronavirus task force to help the government combat the disease. As the head of the NIH - a government agency responsible for biomedical and public health research - Collins said that he was prepared to ‘say the truth’ to President Trump even if he disagreed with it. This followed the repudiation experience of leading immunologist and government adviser, Dr Tony Fauci. A prominent public figure in the fight against coronavirus, Dr Fauci is a ‘truth-teller who is incapable of doing anything except saying exactly what we do and don't know’. Collins added, ‘If there is one thing more infectious than virus, it is hope.’
