Summary
This study tested whether a nasal spray containing heparin, a common and safe medicine, can reduce the spread of COVID-19 among people living in the same home. Over 500 adults and children who lived with someone who tested positive for COVID-19 used the spray or a dummy spray three times daily for 10 days. The goal was to see if fewer household contacts caught the virus compared to those using the placebo.
