Reducing acute severe respiratory events in health care workers during the Covid-19 pandemic with OM85

Covid-19 causes severe respiratory infection, leading to death in some. Health care workers are at high risk of infection. To protect health care workers we propose a clinical trial to reduce respiratory illnesses using a drug called OM85 that has been used safely in Europe for decades. We hypothesise that OM85 will protect health care workers from developing the most serious respiratory infections, saving lives and allowing them to safely treat patients.
