Preventing COVID-19 in Healthcare Workers With HCQ: A RCT

Prophylactic Hydroxychloroquine vs Vitamin C in Healthcare Workers at Risk of COVID-19: A RCT

Healthcare workers (HCW) at risk of Covid-19 will have baseline serology for SARS-CoV-2 to see if they are already immune to Covid-19. HCW will get baseline assessment and if meeting inclusion criteria and no exclusion criteria they will be randomized in a 2:1 ratio to hydroxychloroquine or Vitamin C on a weekly basis for three months. Subjects will complete daily diary of symptoms and temperature, and will have repeat SARS-CoV-2 serology at 6 weeks and 3 months to determine seroconversion.
