Evaluation Viral RNA and Virus Infectivity in Exhaled Air Before and After Use of One Dose With ColdZyme Mouth Spray

"ColdZyme is a medical device classified as a Class III device, certified according to the European Medical Devices Regulation (2017/745/EU) (MDR). It has been CE-marked since 2013.~ColdZyme is a mouth spray that protects against upper respiratory tract viruses causing common cold and flu-like symptoms. ColdZyme forms a protective moisturizing barrier on the mucous membrane of the oral cavity and throat. The viscous barrier catches the virus and thereby the contact between the virus and the epithelial cells are reduced and avoided, thus the barrier disables the viruses' ability to spread and multiply."
