Abstract: The invention relates to a protective device such as a face mask. The device protects the user from infection and may simultaneously immunise the user against future infection. The invention particularly relates to a protective device comprising a disinfection chamber wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber such that the fluid discharged from the chamber comprises inactive microorganisms, for example a device comprising a disinfection chamber in fluid communication with a face mask and wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber to the mask such that the fluid discharged from the chamber to the mask comprises inactive microorganisms. The invention also relates to a method of use of the device.
