We read with interest the article by Estella Ektorp, which describes the death threats received by Marcus Lacerda following a trial on chloroquine for COVID-19 in Brazil.1 We give Lacerda our full support and herein report our experience in France and Switzerland following publication of a meta-analysis2 on hydroxychloroquine, with or without azithromycin, for COVID-19.
