How does the COVID-19 vaccine work?

The COVID-19 vaccine teaches your immune system to recognize the coronavirus. When you get the vaccine, your immune system makes antibodies (“fighter cells”) that stay in your blood and protect you in case you are infected with the virus. You get protection against the disease without having to get sick.

When enough people in the community can fight off the coronavirus, it has nowhere to go. This means we can stop the spread quicker and get a little closer to ending this pandemic.
