COVID-19 Vaccination

At OSF HealthCare, we believe vaccinations against COVID-19 are an important tool to help end the pandemic.

OSF understands concerns individuals may have regarding the development of the vaccines and how that adheres to our Catholic values.

See the FAQs to learn more.

Consent for Minors

Individuals who are minors (age 12 through 17) must be accompanied by an adult (18 years or older).

Written or verbal consent from a parent or guardian is necessary if they’re unable to accompany the minor to the vaccine visit.

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.

What You Need to Know

  • 12 through 17 year olds can only schedule the Pfizer vaccine because it’s the only vaccine the U.S. Food & Drug Administration has approved for people in that age group.
  • Schedule your vaccination at least 90 days after receiving any monoclonal antibodies (BAM IV infusion) or convalescent plasma as part of treatment for COVID-19.

For the Pfizer and Moderna vaccines, you will need to be available to receive a second dose in 21 and 28 days, respectively, following your first dose.

Vaccine Supply

OSF embraces the opportunity to vaccinate our patients and communities. Still, we must rely on the vaccine rollout plan from local health departments, which determine how many vaccine doses OSF receives.

Delays in vaccine shipments to local health departments may require OSF to reschedule vaccine clinic appointments due to a lack of inventory.

Other Vaccine Options

In addition to local health departments and public vaccination sites, retail pharmacies, of which many receive vaccine supply directly from the federal government, also are providing vaccines by appointment. These are the same vaccines administered by local health departments and health care systems.

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 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.

  • Is the COVID-19 vaccine like the flu vaccine where you have to get it every year?

  • The degree to which these vaccines protect against COVID-19 one or two years after vaccination will be determined with more data and time. Trial participants will continue to be monitored, so more will be learned, but it's not yet known whether booster doses will be needed.

  • 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 preteens and teens get vaccinated?

  • Yes, people age 12 and up can receive the Pfizer vaccine only.

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

    Clinical trials are underway by all three companies to study the use in children of younger ages.

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 12.

    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.

  • Is OSF offering a third dose of the mRNA vaccines to the immunocompromised?

  • Yes. Following guidance by the U.S. Centers for Disease Control and Prevention (CDC) , OSF is offering a supplemental (third) dose of the mRNA vaccines – Pfizer and Moderna – to people who are moderately or severely immunocompromised as they are especially vulnerable to COVID-19 and are more at risk of serious, prolonged illness.

    This supplemental dose is given at least 28 days following your second dose of Pfizer or Moderna. Moderately to severely immunocompromised patients includes people who have:

    • Been receiving active cancer treatment for tumors or cancers of the blood
    • Received an organ transplant and are taking medicine to suppress the immune system
    • Received a stem cell transplant within the last two years or are taking medicine to suppress the immune system
    • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
    • Advanced or untreated HIV infection
    • Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response

    Talk to your provider about getting this supplemental dose or send a message to your provider’s office through your  OSF MyChart  account. Learn more from the CDC here.

  • Who can get a COVID-19 booster?

  • On September 24, 2021, the CDC approved the administration of the Pfizer booster. Approval has not been given to Moderna or Johnson & Johnson at this time.

    The CDC recommends boosters for:
    • People 65 years and older and residents in long-term care settings
    • People aged 50-64 years with underlying medical conditions should receive a booster
    • People aged 18-49 years with underlying medical conditions may receive a booster based on their individual benefits and risks
    • People aged 18-64 years who are at increased risk for COVID-19 exposure and transmission because of occupational or institutional setting, such as health care workers, first responders, education staff, food/agriculture, manufacturing workers, corrections workers, U.S. Postal Service, public transit and grocery store workers.

    Learn more about who is eligible here.

    If you received the Pfizer vaccine series at least six months ago and qualify for the booster based on the guidelines above, you can seek out a booster at a retail pharmacy, call your OSF Medical Group provider's office or send a message through OSF MyChart to schedule an appointment. At this time, self-scheduling is not an option. Boosters may not be available at all OSF Medical Group locations.

  • 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?

  • It is too soon to know how long a vaccine will last. It is currently being researched.

  • What do I do after my vaccine visit?

  • Continue to wear your mask, practice physical distancing and wash your hands frequently until you are fully vaccinated, which is two weeks after your second dose of Pfizer or Moderna or after your one-dose vaccine from Johnson & Johnson.
