Vaccines: How They Work & Help

Getting vaccinated is one of many steps you can take to protect yourself and others from COVID-19.

  • Getting the COVID-19 vaccine may help keep you from getting seriously ill even if you do get COVID-19.
  • Getting vaccinated yourself may also protect people around you, particularly people at increased risk for severe illness from COVID-19.
  • COVID-19 vaccination will help protect you by creating an antibody response without having to experience sickness.
  • Vaccines will work with your immune system so it will be ready to fight the virus if you are exposed.
