Use your mouse pointer to aim and click to shoot hand sanitizer at the Coronavirus blobs. Drag Vaccination Shots into yourself to get vaccinated, and you will be immune to all viruses for a period of time shown at the top. Once the syringe is empty, you'll have to keep fighting for your life. Beware! Don't kill green blobs, as that is your immune system coming to help. You have as many lives as immunity cells shown. DON'T DIE!
