There is currently no vaccine to prevent COVID-19 infection. The best way to prevent infection is to avoid being exposed to this virus. The World Health Organization (WHO) provides recommendations to reduce exposure to and transmission of a range of illnesses. Read WHO advice for the public.
Don’t forget to protect yourself from another common virus, the flu (influenza). Everyone 6 months of age and older should get a flu vaccine every season with rare exceptions. Vaccination is particularly important for people who are at high risk of serious complications from influenza. See People at High Risk of Developing Flu-Related Complications for a full list of age and health factors that confer increased risk. To be clear, the influenza virus is a different virus from COVID-19, and getting your flu shot will not protect you from COVID-19. But both viruses are spread in the same fashion and we do have a vaccine to help prevent the spread of the flu. At this time in the United States, your risk of getting the flu is much greater than your risk of contracting COVID-19.
