Quick Facts

How does the COVID-19 vaccine work?  

The vaccine works with your immune system to teach it how to recognize and fend off the virus that causes COVID-19, safeguarding you from getting sick with COVID-19. As your body recognizes and defends you against the infection after the vaccine, you avoid the possibility of suffering from severe illness, long-term health effects, or even death. Receiving the vaccine can be lifesaving, since COVID-19 can affect you and those around you differently.

Just how safe is the COVID-19 vaccine? 

  • The available vaccines went through rigorous studies to ensure safety and efficacy. The vaccines do NOT contain the live virus that causes COVID-19. The vaccine can NOT, and will NOT, make you sick with COVID-19.
  • It takes the body a few weeks to build protection against the virus. This means that a person could get sick just before or just after getting vaccinated because the vaccine has not had enough time to teach the body to recognize and fend off the COVID-19 virus. 

The vaccine is an important tool to stop the pandemic.

  • Getting vaccinated prevents severe illness, hospitalization, and death. Unvaccinated people should get vaccinated and continue masking until they are fully vaccinated. With the new variants, this is more important than ever.   
  • Once fully vaccinated, you can resume activities you did prior to the pandemic. However, to reduce the risk of being infected with COVID-19 variants, or possibly spreading it to others, please adhere to CDC protocol.

What to do after you receive your COVID-19 vaccine.

Sign up for v-safe. This will allow you to use your smartphone to tell the CDC about any side effects you experience after being vaccinated. You will also get reminders if you need a second vaccine dose.
