How does the COVID-19 Vaccine work?

The Immune System—The Body’s Defense Against Infection

To understand how COVID-19 vaccines work, it helps to first look at how our bodies fight illness. When germs, such as the virus that causes COVID-19, invade our bodies, they attack and multiply. This invasion, called an infection, is what causes illness. Our immune system uses several tools to fight infection. Blood contains red cells, which carry oxygen to tissues and organs, and white or immune cells, which fight infection.

COVID-19 Vaccines

COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without us getting the illness. Different types of vaccines work in different ways to offer protection, but with all types of vaccines, the body is left with a supply of white cells (our infection fighting cells) that will remember how to fight that virus in the future.

Sometimes after vaccination, the process of building immunity can cause mild symptoms, such as fever or achiness. These symptoms are normal and are a sign that the body is building immunity.  Mild symptoms may occur the day following the vaccination and resolve within 24-36 hours.

The vaccines are very effective and safe and will not give you COVID-19. The vaccine that will be available in Shelby County is a mRNA vaccine provided by Pfizer and Moderna.  These vaccines contain material from the virus that causes COVID-19, which gives cells instructions for making a harmless protein that is unique to the virus. After cells make copies of the protein, they destroy the genetic material from the vaccine. The body recognizes that the protein should not be there and builds  blood cells that will remember how to fight the virus that causes COVID-19 if we are infected in the future.
