COVID-19 Vaccination

Vaccinations against COVID-19 are a necessary tool to help end the pandemic.

We understand individuals may have concerns regarding the development of the vaccines and how the vaccines adhere to our Catholic values. Learn more.

Getting Vaccinated With OSF

OSF is vaccinating eligible patients against COVID-19. Talk to your provider about getting a vaccine or schedule using OSF MyChart.  Schedule appointment

Vaccine for Kids Ages 5-11

The FDA and CDC have approved a two-dose COVID-19 vaccine by Pfizer specifically for kids ages 5 to 11. The doses are administered 21 days apart. The ability to vaccinate this age group has the potential to have a major positive impact – not only for the health and safety of children, but also in terms of the pandemic as a whole.

OSF is working on the process for administering the vaccine to kids age 5-11 at our OSF Medical Group primary care and pediatric clinics. We are also working to partner and collaborate with local health departments and regional superintendents for other community vaccination efforts. 

Community clinics available

At this time, we have several clinics scheduled in some of the communities we serve.  With extended hours and Saturday appointments available, these clinics offer parents ease and flexibility to be there when their child is vaccinated.

Click on a location below to schedule an appointment in your community. 


Note: Please schedule an appointment for your child to receive their second dose before leaving the clinic where they received their first dose.

Scheduling with your child’s OSF doctor

OSF encourages our patients and families to get vaccinated wherever they can, and not delay if they can obtain the appropriate vaccine dose elsewhere. However, to be ready to schedule an appointment for your child at an OSF Medical Group clinic when office appointments become available, please make sure you have  access to your child’s records through your OSF MyChart account.

Stay Informed

Check back to this page as it will be updated when additional clinics are scheduled and when appointments can be made at OSF Medical Group offices. Please also follow OSF HealthCare on Facebook for updates. You can also seek out other vaccine opportunities, such as retail pharmacies and your local health department.

Supplemental Doses for Immunocompromised

As approved by the CDC, OSF is providing supplemental third doses to people who received a two-dose mRNA vaccine (Pfizer or Moderna) and are moderately or severely immunocompromised. These individuals are especially vulnerable to infection from COVID-19 and are more at risk of serious, prolonged illness.

This supplemental dose must be the same vaccine (Pfizer of Moderna) of the initial vaccine series. It is given at least 28 days following the second dose. If you qualify, schedule an appointment through OSF MyChart.

Booster Shots

The CDC and FDA have approved the use of boosters for all three available vaccines in people age 18 and older. Any of the three authorized vaccines (Pfizer, Moderna or Johnson & Johnson) can be used as a booster in a “mix-and-match” approach . This means you can receive any of the available vaccines as a booster shot if you are age 18 or older:

  • Individuals who received the two-dose Pfizer or Moderna vaccine as their primary vaccine can get a booster shot of any of the three available vaccines at SIX months or more after receiving the second dose of their primary vaccine.
  • Those who received the one-dose Johnson & Johnson COVID-19 vaccine as their primary vaccine can get a booster shot of any of the three available vaccines TWO months after they received their single primary dose.

Talk to your provider if you’re unsure about getting a booster or schedule through OSF MyChart . Vaccine brand availability may vary by location.

At this time OSF is only offering Pfizer and Moderna boosters. The Johnson & Johnson vaccine is not available at OSF clinics.

Not an OSF Patient?

You’ll be prompted to answer some questions and provide your name and contact information. You’ll receive a confirmation code and an email or text with a unique link to schedule your appointment.

PLEASE NOTE: if you have already received your first vaccine dose, you should try to schedule the second dose at the same clinic location. If you cannot schedule at that location, please contact your primary care provider for assistance.

Consent for Minors

Individuals who are minors (age 5 through 17) must be accompanied by an adult (18 years or older) at their appointment to be vaccinated.

  • If you are a parent or guardian and are unable to attend the vaccine visit, please  complete a parental consent form prior to the appointment
  • Or be prepared to provide written information on how we can obtain verbal consent from you at the time of the visit

Other Vaccine Options

In addition to OSF, you can also get vaccinated at your local health department, state vaccine clinics and retail pharmacies.

Frequently Asked Questions

Catholic Values

  • What is the position of OSF on the vaccines and the use of fetal cells?
  • As a Catholic or person of faith, you may have questions about whether the development of the COVID-19 vaccines was ethical. You may even wonder about the content of the vaccines themselves.

    For years, the Catholic Church has been concerned about fetal cell lines used for the development and culturing of vaccines. The vaccines from Pfizer and Moderna first raised concerns because fetal cell lines were used for testing purposes, but not in their production. However, an abortion-derived cell line was used in the development, testing and production of the Johnson & Johnson vaccine. No fetal cells or tissue, however, are used in the vaccine itself.

    At this point in the pandemic emergency, OSF will not turn away the Johnson & Johnson vaccine if it is the only option available for our patients. We will communicate to patients which vaccine they are receiving and they can make their own choice as to whether to accept it.

    Both the Vatican and the United States Conference of Catholic Bishops (USCCB) have released statements for people of faith to consider. The Vatican has stated that in this pandemic emergency, a wide range of vaccines that are available now may be used to protect ourselves and others. The USCCB has stated that being vaccinated is an act of charity that serves the common good. When an individual does not have a choice in which vaccine to receive, it is morally acceptable to receive any of the vaccines with a clear conscience.

General COVID-19 Vaccine Questions

  • What do we know about COVID-19 vaccines?

  • The Food & Drug Administration (FDA) on December 11, 2020, granted Pfizer-BioNTech emergency use authorization (EUA) for its COVID-19 vaccine to be used in people age 16 and older. On May 10, 2021, the FDA amended its original EUA for Pfizer to allow for the vaccine to be administered to people over the age of 12.

    On August 23, 2021, the FDA gave Pfizer full approval for use in people age 16 and older. The EUA continues for individuals age 12 to 15 and for supplemental use as a third dose for individuals who are moderately or severely immunocompromised. On November 2, 2021, the CDC gave approval – following the FDA’s approval week’s earlier – for administration of a lower dose Pfizer vaccine in children ages 5 to 11.

    On September 24, 2021, the CDC approved the administration of the Pfizer booster.

    The FDA on December 18, 2020, granted EUA to Moderna for its COVID-19 vaccine to be used in people age 18 and older. Full approval is pending for Moderna.  

    On February 27, 2021, the FDA granted EUA to Johnson & Johnson for its vaccine to be used in people age 18 and older. As of August 27, 2021, Johnson & Johnson has not yet filed for full approval by the FDA.

    Research and review is given to all vaccines by the FDA.

  • Why should I get the COVID-19 vaccine?

  • Vaccination will help keep you from getting COVID-19.

    A vaccine teaches your body’s immune system to recognize a virus or bacteria so that you can fight off an infection without getting sick.

    Read more from the CDC.

  • How effective are the three COVID-19 vaccines?

  • All three COVID-19 vaccines are highly effective at preventing hospitalizations or death, according to clinical study results the companies provided to the U.S. Food & Drug Administration (FDA).

    A vaccine’s efficacy is determined during clinical studies by looking at the difference in new cases of the virus between the group that received the experimental vaccine and the group that did not. Pfizer and Moderna both had efficacy rates of about 95% during clinical trials and Johnson & Johnson had a 66.9% efficacy rate. But what do those numbers actually mean?

    The efficacy rate means that out of the people who were vaccinated, their risk was that percent lower of getting COVID-19 compared with the group that wasn’t vaccinated.

    But comparing Johnson & Johnson to Pfizer and Moderna efficacy rates on their own is like comparing apples to oranges. That’s because the Johnson & Johnson clinical trials happened at different times during the pandemic and in different geographic areas where the variants of COVID-19 were circulating.

    All three vaccines, however, were nearly 100% effective at preventing severe disease resulting in hospitalization or death – six weeks after the first dose for Moderna, seven weeks after the first dose for Pfizer and seven weeks after the one-dose Johnson & Johnson vaccine.

  • Will I have to pay for my COVID-19 vaccine?

  • The COVID-19 vaccination is free, as it was purchased by the federal government.

    Health care providers, however, are allowed to charge an administrative fee. 

    This administrative fee helps cover costs associated with things such as wages for the health care workers who are giving the shots and documenting your patient information, and for storing and transporting the vaccine for use at vaccination clinics. Insurance plans and governmental payers are required to pay for the administration fees with no out-of-pocket expense to you.

    OSF HealthCare also believes no individual should have to pay for this administrative fee. If you do not have insurance, OSF will not pass the administration costs on to you. 

    If you receive a bill for the administrative fee or a notice from your insurance company that the administrative fee is being applied toward your deductible, please contact OSF HealthCare at (800) 421-5700 and a financial navigator will assist you.

    At OSF HealthCare, we are dedicated to serving you with the greatest care and love.

  • How do the COVID-19 mRNA vaccines work?
  • COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without getting sick. With all types of vaccines, the body is left with a supply of antibodies that will remember how to fight that virus in the future.

    Read more from the CDC.

  • What kind of vaccine is the Johnson & Johnson vaccine?

  • The Johnson & Johnson vaccine is a viral vector vaccine that uses a type of virus, such as one that causes the common cold. The vector (the virus with its protein stripped out) carries a gene from the coronavirus into human cells, which then produce the spike protein of the coronavirus, but not the virus itself.

    Like mRNA vaccines, it’s the spike protein that primes the immune system to fight off future exposure to the virus that causes COVID-19.

  • What should I do before my vaccine?

  • Talk to your doctor about getting a vaccine for COVID-19. Remember to bring your mask, and any other additional identification materials required by your vaccination center.

  • What can I expect at my vaccine visit?

  • Wear your mask into the vaccine clinic and during your vaccination. You should receive a vaccination card or printout that tells you what COVID-19 vaccine you received, the date you received it and where you received it. You will also get a paper or an electronic version of a fact sheet from the manufacturer of the authorized COVID-19 vaccine that you received. Make sure you review this and ask any questions you may have before leaving. If your vaccine requires two doses, make sure to schedule your second dose.

  • Which lasts longer – immunity after the vaccine or immunity from having been infected with COVID-19?

  • We won't know how long immunity lasts after vaccination until there is more data on how well COVID-19 vaccines work in real-world conditions. We don't know how long immunity lasts after someone has a COVID-19 infection, however this is why the Centers for Disease Control and Prevention (CDC) recommends getting vaccinated even after having COVID-19.  

  • What percentage of the population needs to get vaccinated to achieve herd immunity?

  • Herd immunity means that enough people in a community are protected from getting a disease because they've already had the disease or they've been vaccinated. Herd immunity makes it hard for the disease to spread from person to person, and it even protects those who cannot be vaccinated, like newborns. The percentage of people who need to have protection in order to achieve herd immunity varies by disease. The CDC and other experts are studying herd immunity and will provide more information as it is available. Public health officials have a goal of vaccinating 80% of the population to achieve herd immunity.

  • Do I need to get a booster of the COVID-19 vaccine?

  • At this time, the CDC and FDA are recommending individuals who are immunocompromised get a third dose 28 days after their second dose if they received Pfizer or Moderna or get a second dose 28 days after receiving the one-dose Johnson & Johnson vaccine.

    Booster shots have been approved for people age 18 and older to extend the immunity of the original vaccine they received. If you received Pfizer or Moderna, you should get a booster six months after your second dose. If you received the Johnson & Johnson vaccine, you should get a booster two months after your original vaccine. 

  • Should I take any over-the-counter pain medications prior to getting vaccinated?

  • The COVID-19 vaccines may cause side effects, such as pain and swelling at the injection site, along with fever, chills, headache and fatigue. These symptoms are signs that your immune system is responding as it’s supposed to.

    The Centers for Disease Control and Prevention does not recommend taking medications such as acetaminophen (Tylenol), ibuprofen (Advil) or antihistamines (Benadryl) prior to receiving the vaccine. Taking these medications may mask any existing symptoms you may be experiencing in addition to any allergic reaction you may have following the vaccination.

    You can take these over-the-counter medications to relieve post-vaccination side effects if you have no other medical reasons that prevent you from taking these medications normally.

Vaccine Safety

  • Should I be concerned that the vaccines have been put on the ‘fast track?’

  • No. Fast track does not mean cutting corners or skipping over clinical trials.

    Clinical trials include studying thousands of individuals who volunteered to get the COVID-19 vaccine before it was FDA approved. They were watched over by the medical scientists to determine how well the vaccine worked to create immunity from COVID-19.

    Fast track – in the case of COVID-19 vaccines – is all about the intense focus to create a vaccine that is in great need.

  • How do we know these vaccines are safe?

  • Prior to the FDA granting EUA, the safety and efficacy of the vaccines were reviewed by scientists and public health experts. These include:

    • Panels of independent experts retained by the companies
    • FDA scientific staff
    • An independent panel of experts brought together by the FDA
    No serious safety concerns have been reported for the Pfizer or Moderna vaccines.

    Once a vaccine is released to the public, the CDC and the FDA continue to monitor individuals who receive the vaccine for any safety issues.
  • Does the vaccine cause side effects?

  • After COVID-19 vaccination, you may have some side effects. This is a normal sign that your body is building protection.

    The CDC states that acetaminophen (Tylenol) and/or ibuprofen (Advil) may be taken AFTER you receive the vaccine if you develop side effects such as fever, chills, muscle aches or pain, or reddening of the skin at the injection site. Taking any over-the-counter pain relief medication prior to receiving the vaccine is not recommended. Consider applying ice locally to the injection site if you experience any swelling or soreness.

    Mild to moderate side effects reported during clinical trials were more common following the second dose with the Pfizer and Moderna vaccines. Those side effects include fever, headache, redness around the location of the shot and muscle pain or muscle aches.

    During clinical trials with the Johnson & Johnson one-dose vaccine, the most common side effects were pain around the injection site, headache, fatigue and muscle pain.

    The Johnson & Johnson vaccine was paused after six women developed rare and severe blood clots. The CDC and FDA has lifted the pause and issued updated information about the risk of developing blood clots on the revised fact sheet.

    Please consult your personal physician for questions.

  • I take medication for a chronic condition. Will the vaccine interfere with that medication?

  • Overall, the COVID-19 vaccine has very little drug-to-drug interaction. In fact, very few vaccines do. It would be safe to receive the vaccine in combination with most medications. If you have concerns or questions, however, you should reach out to your doctor or your pharmacist so they can answer your questions.

Supply & Availability

  • Do the OSF retail pharmacies offer the COVID-19 vaccine?

  • At this time, the OSF Pharmacy locations do not offer a vaccination program. Other retail pharmacies are beginning to receive COVID-19 vaccine for administering to the public. Administering vaccines is not a new service for retail pharmacies, as they offer a variety of adult vaccine programs. While we encourage our patients to seek out a vaccination through OSF when possible, getting vaccinated is the main goal and having more locations to provide vaccinations gives people more opportunity to do that.

  • Can young children, preteens and teens get vaccinated?

  • Yes, kids and teens ages 5 to 17  can receive the Pfizer vaccine only. Kids age 5 to 11 can receive a lower dose of the two-dose Pfizer than what is administered to people age 12 and up.

    Anyone 18 or older can also receive the Modern and Johnson & Johnson vaccines.

Who Can Get a COVID-19 Vaccine?

  • Who should not receive a COVID-19 vaccine?

  • The FDA has not authorized a COVID-19 vaccine for children under the age of 5.

    You should not proceed with a COVID-19 vaccine if you:

    • Have received monoclonal antibodies or convalescent plasma in the last 90 days
    • Are currently experiencing symptoms associated with COVID-19, such as a cough, fever or headache
    • Have experienced anaphylaxis (a severe allergic reaction) to a COVID-19 vaccine or any ingredient in the vaccines
    Talk with your doctor if you:
    • Have a compromised immune system due to a health condition or treatment
  • Can I get the vaccine if I’ve previously received passive antibody therapy for the treatment of COVID-19?

  • Yes, you can be vaccinated, but you must defer vaccination for at least 90 days if you have received COVID-19 monoclonal antibody therapy (bamlanivimab – BAM – or COMBO infusion) OR convalescent plasma. There is no recommended minimum interval between non-COVID-19 antibody therapies and the mRNA COVID-19 vaccine.

  • What if I received a vaccine recently for another disease, such as pneumonia or shingles. Can I still get the COVID-19 vaccine?

  • Yes, you can still get the COVID-19 vaccine.

  • Should I get the vaccine if I’m pregnant or planning to get pregnant?

  • COVID-19 vaccination is recommended by the CDC for people who are pregnant, breastfeeding, trying to get pregnant now, or might become pregnant in the future.

    Evidence about the safety and effectiveness of COVID-19 vaccination during pregnancy has been growing. These data suggest that the benefits of receiving a COVID-19 vaccine outweigh any known or potential risks of vaccination during pregnancy.

    Although the overall risk of severe illness is low, pregnant and recently pregnant people are at an increased risk for severe illness from COVID-19 when compared with non-pregnant people. Severe illness includes illness that requires hospitalization, intensive care, need for a ventilator or special equipment to breathe, or illness that results in death.

    Additionally, pregnant people with COVID-19 are at increased risk of preterm birth and might be at increased risk of other adverse pregnancy outcomes, compared with pregnant women without COVID-19.

    Get the latest guidance from the Centers for Disease Control and Prevention (CDC).

  • Do the COVID-19 vaccines affect fertility in women or men?

  • When it comes to fertility, experts are more concerned about the impact of the virus itself rather than the vaccine.

    For men, researchers identified the SARS-CoV-2 virus can enter the testes, but it remains unclear how significant the impact is on male fertility at this time. Because the COVID-19 vaccines do not use the live virus, we do not expect them to have an impact on male fertility.

    For women, infertility is not known to occur as a result of the COVID-19 virus or the mRNA COVID-19 vaccines.

    Reports on social media that claim the vaccines could cause infertility or are involved in the formation of the placenta are false, and the FDA is concerned that this misinformation may cause women to avoid vaccination unnecessarily.

  • What if I have tested positive for COVID-19?

  • COVID-19 vaccines should be offered regardless of a person’s prior positive COVID-19 infection. However, someone with a current COVID-19 infection should wait until recovering from all symptoms and until they are cleared to discontinue isolation before receiving the vaccine.

  • I participated in an investigational trial for a COVID-19 vaccine. What should I do?

  • If you participated in an investigational trial for a COVID-19 vaccine and are unsure if you received the vaccine or a placebo, you need to contact the trial to ask them to unblind what you received during the trial. This will provide you the information to tell you if you’ve actually been vaccinated.

After Receiving the Vaccine

  • If I get a COVID-19 vaccine, do I still need to wear a mask around others?

  • No, but you have to be fully vaccinated, which means two weeks after your second dose of Pfizer or Moderna or two weeks after the one-dose Johnson & Johnson vaccine. Afer that, you can:

    • Go mask-free outdoors and indoors, except where state or local law or business and workplace guidance requires a mask.
    • You should still watch out for symptoms of COVID-19, especially if you've been around someone who is sick. If you have symptoms of COVID-19, you should get tested and stay home and away from others.
    • People who have a condition or are taking medications that weaken the immune system, should talk to their health care provider to discuss their activities. They may need to keep taking all precautions to prevent COVID-19.

    However, you should still protect yourself and others in many situations by wearing a mask that fits snugly against the sides of your face and doesn’t have gaps. Take precaution whenever you are:

    • In a health care setting or where required by state or local law or business and workplace guidance

    It’s important for everyone to continue using all the tools available to help stop this pandemic as we learn more about how COVID-19 vaccines work in real-world conditions.

    If you're not vaccinated:

    • Wear a mask when around others
    • Stay at least 6 feet away from others
    • Avoid crowds
    • Wash your hands often
  • How long after the vaccine am I immune?

  • It typically takes a few weeks for the body to build immunity after vaccination. That means it's possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and still get sick.

  • How long will the vaccine protect me?

  • Research continues, but at this time, boosters for all three vaccines are recommended at six months following the second dose of Pfizer or Moderna or two months following the one-dose Johnson & Johnson vaccine.

  • What do I do after my vaccine visit?

  • Continue to wear your mask, practice physical distancing and wash your hands frequently. Additionally, follow up with a booster six months after receiving the second dose of Pfizer or Moderna or two months after receiving the one-dose Johnson & Johnson vaccine.
