Coronavirus Info Guide: Vaccines

Note: This page is regularly updated with news from the Lake County Health Department and other reliable sources.

Vaccinations protect you and others

  • COVID-19 vaccines are safe and effective: they help prevent severe symptoms, hospitalization, long COVID, and death. 
  • Breakthrough cases in fully vaccinated people are uncommon and lead to less severe illness than among unvaccinated people with COVID-19. 
  • People who are unvaccinated are 5 times more likely to catch COVID-19 than those who are vaccinated, more than 10 times more likely to be hospitalized from COVID-19 than those who are vaccinated, and more than 10 times more likely to die from it.
  • As more people are vaccinated, stress on the healthcare system will decrease. Because of the current surge in COVID-19 cases in people who aren't vaccinated, hospital ICU beds may be scarce, reducing the availability of care for other urgent health problems like heart attacks, strokes, and appendicitis.

Get vaccinated now

Vaccines are widely available and anyone age 12 and older may walk in or schedule an appointment. Ages 12–17 will receive the Pfizer vaccine and must be accompanied by a parent or guardian. U.S. citizenship is not required.

COVID-19 vaccine booster for some

The U.S. Food and Drug Administration (FDA) authorized a booster dose of the Pfizer-BioNTech COVID-19 vaccine for certain fully vaccinated individuals. The CDC has recommended that people in these groups receive a third shot of the Pfizer-BioNTech vaccine:  

  • Ages 65 & older 
  • Residents in long-term care settings 
  • Ages 50–64 with underlying medical conditions  

People in these groups should consider receiving a booster dose of the Pfizer-BioNTech vaccine based on their individual benefits and risks:  

  • Ages 18–49 years with underlying medical conditions 
  • Ages 18–64 years who are at increased risk for COVID-19 exposure and transmission because of occupational or institutional settings such as healthcare workers, teachers, grocery store employees, and other essential workers. 

If you believe you qualify for a booster, contact your healthcare provider for more information.

At your vaccination

You will

  • be required to wear a mask at all times
  • be monitored for 15 minutes after you receive the vaccination.
  • receive a vaccination card stating which COVID-19 vaccine you got, when and where you were vaccinated. Do not share your vaccination card on social media.
  • receive a fact sheet (paper or electronic) that tells you more about the COVID-19 vaccine you got. 


After you're vaccinated

  • Follow any instructions you were given at your appointment.
  • If you receive the 2-dose vaccine, make sure you get both doses; your provider will give you scheduling information.
  • It takes 2 weeks for your body to build immunity to COVID-19 after you receive the 1-dose vaccine or the second of a 2-dose vaccine.
  • What to expect after getting a COVID-19 vaccine, from the CDC.
  • COVID-19 vaccines and rare severe allergic reactions, from the CDC.
  • Use V-safe: this smartphone-based tool from the CDC uses text messaging and brief surveys to provide personalized health check-ins after you receive a COVID-19 vaccine.

Guidelines for fully vaccinated people

  • Everyone ages 2 & up is required to wear a face mask in indoor public spaces throughout Illinois. 
  • Expect to wear a mask wherever else required by laws, rules, regulations, or local guidance, including on public transportation and terminals. Carry a mask with you and pay attention to posted requirements wherever you visit.
