There is currently no vaccine for coronavirus. Coronavirus is an RNA virus, which is structurally prone to mutation, so even if a vaccine is developed, the virus can mutate to render the vaccine ineffective. To prevent coronavirus infection, wear a mask in your daily life, especially when you go out, and try to keep a distance of more than 1 meter when someone is communicating with you, to effectively avoid the spread of droplets. When touching the relevant items in public places, you should wash your hands in time with hand sanitizer to avoid virus residue on your hands. If you can’t wash your hands in time, you should try to avoid touching the eyelids, nose, mouth and other mucous membrane parts to avoid mucous membrane exposure.
