Why get a COVID-19 vaccine?

  • Getting a COVID-19 vaccine is a safer, more reliable way to build protection than getting sick with COVID-19. Vaccination helps protect you by creating an antibody response without you having to experience potentially severe illness or post-COVID conditions.
  • Getting sick with COVID-19 can cause severe illness or death, and we can’t reliably predict who will have mild or severe illness.
  • You may have long-term health issues after having COVID-19. Even people who do not have symptoms when they are first infected can have these ongoing health problems, also known as long COVID or post-COVID conditions.
  • While people can get some protection from having COVID-19, the level and length of that protection varies and is not as strong as immunity from vaccinations.
  • Serious side effects that could cause a long-term health problem are extremely rare following any vaccination, including COVID-19 vaccination. The benefits of COVID-19 vaccination outweigh the known and potential risks.
