Getting Both Vaccines 

We don’t know what this flu season will be like but we do know that having flu and COVID-19 at the same time can be even worse than having one or the other by itself. Children under 5 years old, pregnant people, and adults over 65 years old are at high risk of getting sicker from flu. The flu vaccine is recommended for everyone over the age of 6 months. The COVID-19 vaccine is recommended for everyone 5+ years and older, especially for seniors and people with underlying medical conditions who are at higher risk for severe complications.

COVID-19 vaccines are safe to co-administer with any other vaccines on the same day, including the flu vaccine. They can either be given one in each arm or spaced out on the same arm. Both flu and COVID-19 (Pfizer and J&J) are available at no out-of pocket cost. 

No. You should look out for arm soreness and redness as well as flu-like symptoms (including fever, cough, nausea, vomiting, muscle aches, headache) for 48-72 hours after being vaccinated. Contact your primary care provider if you have any concern about the symptoms or have symptoms for more than 72 hours. 

Both vaccines are widely available citywide and offered at many doctor’s offices and pharmacies.

CDPH immunization clinics are also open for Flu and COVID-19 vaccines to all Chicago residents eligible for the vaccine, including youth and adults, regardless of insurance status.

If you received your COVID-19 vaccine in the state of Illinois, go to to access your vaccination records through the Illinois Department of Public Health "Vax Verify" portal.

Yes. You should get the vaccine even if you have already had COVID-19. Some people have gotten COVID-19 after getting vaccinated. However, this is rare. The vaccine also offers more protection against reinfection than your body could develop on its own from already having COVID-19. You can get vaccinated as soon as you are out of your isolation period and are feeling better.

Even after someone has been vaccinated the individual should continue to wear a mask and maintain social distancing.
