N°spécial de revue/special issue: The Coronavirus pandemic is imposing tremendous health impacts around the world. At the time of writing (20th July 2020) there have been nearly 15 million cases worldwide and well over half a million deaths from the Covid-19 disease caused by the virus. The fact that this statement needs to be effectively date-stamped reflects the rapid development of this pernicious virus. While several vaccines are under rapid development, so far it is unclear if any will be truly effective given the ability of the virus to mutate; already the vast majority of Covid-19 cases are caused by a virus which is no longer identical to that which appeared in Wuhan in late 2019.
