Can I walk in for a flu shot in Bolingbrook?
Yes. You do not need an appointment for a flu shot. We’re open every day of the week, including Saturday and Sunday, from 8 AM to 8 PM, and walk-ins are welcome. We are not open 24 hours.
If you prefer a set time, save your spot online. After 8 PM, the online schedule shows tomorrow’s openings, so you can book your flu shot the night before.
Flu vaccine supply can change during the season, and some vaccines are made for specific age groups. If you want a particular type, such as a higher-dose vaccine for someone 65 or older, call (630) 914-5373 before you come and ask what we have in stock.
Who should get a flu vaccine this season?
CDC’s flu vaccine guidance for the 2026 to 2027 season says everyone 6 months and older, with rare exceptions, should get a flu vaccine every season. Vaccination lowers the risk of getting sick with flu, of being hospitalized with it and of dying from it.
The shot matters most for people who are more likely to have a serious case. CDC’s list of higher-risk groups includes these adults:
- Adults 65 and older
- People who are pregnant, and for 2 weeks after the pregnancy ends
- People with asthma, COPD or other chronic lung disease
- People with heart disease, diabetes, or kidney or liver disorders
- People with a weakened immune system from an illness or a medicine
- People who have had a stroke, and people with a BMI of 40 or higher
- Residents of nursing homes and other long-term care facilities

When is the best time to get a flu shot?
For most adults, the shot fits best in September or October, and CDC’s goal is for everyone to be vaccinated by the end of October.
Your body makes protective antibodies about two weeks after the shot, so getting it before flu is spreading widely gives that protection time to build. CDC also advises most adults, and especially people 65 and older, not to get vaccinated early in July or August, because protection may decrease over time.
If October slips by, come in anyway. CDC’s vaccine advisory committee, in its most recent published flu recommendations, says vaccination should continue after October and throughout the flu season as long as flu viruses are circulating. In the United States, flu usually spreads between October and May, so a shot in November, December or January is still worth getting.
What happens at a flu shot visit
A flu shot visit starts with the same check-in as any other visit here. After that, a member of our team goes over a few safety questions with you and gives the shot.
Tell us before the shot if any of these apply to you:
- You had an allergic reaction after a past flu vaccine
- You have any severe, life-threatening allergies
- You have ever had Guillain-Barré syndrome
- You feel moderately or severely ill today
Read the vaccine sheet ahead of time
You can read CDC’s Vaccine Information Statement for the flu shot before you come. It explains the benefits and risks of the vaccine in plain language. People sometimes faint after a shot or any medical procedure, so let us know if you feel dizzy, notice vision changes or hear ringing in your ears afterward.
What to bring to your flu shot
A few items make check-in faster:
- A photo ID
- Your insurance card or Medicare card, if you are using coverage
- A list of your medicines and allergies
- Details of any reaction you have had to a past vaccine
- A short-sleeved shirt, or a top with sleeves that roll up easily
Proof of vaccination for work or school
If your employer or school asks for proof of a flu shot, call us before your visit and ask what paperwork we can give you. That way you know what to expect when you leave.
Walk in for your flu shot this week
Stop by any day, no appointment needed, or save your spot online and come in at a time that fits your day.
Flu shot side effects and when to wait
Side effects from a flu shot are usually mild and short-lived, and the shot cannot give you the flu.
CDC explains that the viruses in a flu shot are killed, so they cannot cause flu illness. Some people have soreness, redness or swelling where the shot was given, a headache, fever, muscle aches, nausea or tiredness afterward.
A cold or other mild illness is usually not a reason to put off the shot. If you are moderately or severely ill, it is better to wait until you recover. If you have ever had Guillain-Barré syndrome within 6 weeks of a flu vaccine, talk with us or your regular doctor first, because CDC’s advisers list that history as a reason for extra caution.
Flu testing and treatment if you are already sick
A flu shot helps prevent flu, but it does not treat an infection you already have. If you have fever or chills, cough, sore throat, body aches, headache or unusual tiredness, come in for a sick visit instead. We can run a rapid flu test here, along with rapid strep and COVID tests when the cause is not clear.
Timing matters. CDC says flu antiviral medicines work best when started early, ideally within two days after symptoms begin, so people in a higher-risk group should not wait several days to be seen. Our page on flu testing and treatment has more on flu symptoms and testing.
Is a flu shot covered by insurance?
Many plans cover a yearly flu shot at no cost when an in-network provider gives it, but coverage varies, so check before you come.
We accept Aetna, Cigna, Medicare, Blue Cross Blue Shield of Illinois, UnitedHealthcare, Humana and Illinois Medicaid plans, including HFS, Meridian, CountyCare, Molina and YouthCare. Call (630) 914-5373 to confirm your specific plan.
HealthCare.gov puts the flu shot on its list of adult preventive vaccines that every Marketplace plan, along with many other health plans, has to cover with no copayment or coinsurance. That generally applies when an in-network provider gives the shot, even if you have not met your deductible. The same page cautions that coverage can vary and that a no-cost shot is not guaranteed in every case.
Medicare Part B covers the seasonal flu vaccine, usually one shot each flu season. According to Medicare.gov, the shot costs you nothing when the provider giving it accepts assignment. Our Medicare page explains how Medicare works at our clinic. If you do not have insurance, you can pay for the shot yourself; call for current self-pay pricing.
Can children get a flu shot here?
Plan on your child’s own doctor or a county health department clinic for a child’s flu shot, because we do not give routine childhood vaccinations. If you have a question about your child, call (630) 914-5373 to ask.
In Will County, the health department offers childhood and adult vaccines at clinics in Joliet, Monee and Bolingbrook, where its office is at 323 Quadrangle Dr. Appointments for all three are made by phone at 815-740-8143. DuPage County families can call the DuPage County Health Department at 630-682-7400; it holds childhood immunization clinics in Wheaton, Westmont and Lombard, and clinic times and vaccine supply can vary. When you call either one, ask which flu vaccines they have for your child’s age.
A sick child is a different story. Our pediatric urgent care treats babies, school-age kids and teens, and we can run rapid flu, strep and COVID tests during that visit.

Questions and answers
Questions we hear often
Still not sure? Call (630) 914-5373 and we will help you decide.
Do I need an appointment for a flu shot?
No. Walk-ins are welcome every day, and we’re open 8 AM to 8 PM, weekends included. Tell the front desk you are there for a flu shot. You can also reserve a time on our booking page. After 8 PM, the page lists openings for the following day.
Where can I get a flu vaccination near Bolingbrook?
Pioneer Physicians Urgent Care is at 148 S Bolingbrook Dr in Bolingbrook, open 7 days a week from 8 AM to 8 PM. Romeoville is about 10 minutes away by car, and downtown Naperville about 18. For children’s vaccines, try your pediatrician’s office first, or the Will County Health Department’s Bolingbrook office on Quadrangle Dr.
Is a flu shot covered by insurance?
Often, yes. HealthCare.gov says every Marketplace plan, and many other health plans, has to cover the flu shot without a copay when an in-network provider gives it, and Medicare Part B covers the seasonal flu vaccine, usually once each flu season. Coverage varies, so call (630) 914-5373 to confirm your specific plan. If you are uninsured, ask about current self-pay pricing.
Can the flu shot give me the flu?
No. CDC explains that the viruses in a flu shot are killed, so the shot cannot cause flu illness. Some people get a sore, red or swollen arm, a headache, fever, muscle aches, nausea or tiredness afterward. CDC says these effects are usually mild and short-lasting.
How long does it take for a flu shot to work?
About two weeks. CDC says the body develops antibodies about two weeks after vaccination. That is one reason CDC suggests getting vaccinated by the end of October, before flu usually picks up. If you are exposed to flu during those first two weeks, you may not be fully protected yet.
Is it too late to get a flu shot in December or January?
No. CDC’s vaccine advisory committee says vaccination should continue throughout the flu season as long as flu viruses are circulating. In the United States, flu usually spreads between October and May, so a winter shot is still worth getting. You can walk in any day, no appointment needed.
Do you have the high-dose flu shot for people 65 and older?
Call (630) 914-5373 to ask which flu vaccines we have this season. For adults 65 and older, CDC prefers a higher-dose, recombinant or adjuvanted flu vaccine over a standard-dose shot. If none of those is available, CDC says to get another flu vaccine approved for your age rather than skip the shot.
Can I get a flu shot if I am allergic to eggs?
Yes, in most cases. CDC’s vaccine advisers recommend that people with an egg allergy get a flu vaccine, and say any flu vaccine that fits your age and health can be used. Tell us about the allergy anyway. If you have ever had a severe reaction to a flu vaccine itself, talk with us before the shot.
