Summary

Rationale: Covid-19 spreads rapidly throughout the world. A large epidemic in the Netherlands would seriously challenge the available hospital capacity, and this would be augmented by absenteeism of healthcare workers (HCW). Strategies to prevent absenteeism of HCW are, therefore, desperately needed to safeguard continuous patient care. Bacille Calmette-Guérin (BCG) is a vaccine against tuberculosis, with protective non-specific effects against other respiratory tract infections in in vitro and in vivo studies, and reported significant reductions in morbidity and mortality. The hypothesis is that BCG vaccination can reduce HCW absenteeism during the epidemic phase of Covid-19.

Objective: Primary objective: To reduce absenteeism among HCW with direct patient contacts during the epidemic phase of Covid-19. Secondary objective: To reduce hospital admission, ICU admission or death in HCW with direct patient contacts during the epidemic phase of Covid-19.

Study design: A placebo-controlled adaptive multi-centre randomized controlled trial.

Study population: HCW with direct patient contacts among which nurses and physicians working at emergency rooms and wards where Covid-19-infected patients are treated.

Intervention: Participants will be randomized between intracutaneous administration of BCG vaccine or placebo in a 1:1 ratio.

Main study parameters/endpoints: Primary endpoint: number of days of (unplanned) absenteeism for any reason. Secondary endpoints include the number of days of (unplanned) absenteeism because of documented Covid-19 infection, and the cumulative incidence of hospital admission, Intensive Care Admission, and death.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Based on previous experience and randomized controlled trials in adult and elderly individuals, the risks of BCG vaccination are considered low. The objective of this trial is to evaluate the beneficial effects of BCG vaccination through a lower work absenteeism rate of HCW and/or a mitigated clinical course of Covid-19 infection. The primary endpoint and the adaptive design with frequent interim analyses facilitate maximum efficiency of the trial, so that results can inform policy making during the ongoing epidemic.
