Yes. COVID-19 vaccination works by teaching your immune system how to recognize and fight the virus that causes COVID-19, and this protects you from getting sick with COVID-19.

There is no way to know how COVID-19 will affect you, even if you don’t have an increased risk of developing severe complications. Learn more about how COVID-19 vaccines work.
