COVID-19 Vaccine FAQ

When can I get my COVID-19 vaccine from Oswald’s Pharmacy?

Illinois state and county health departments are determining individuals’ eligibility to receive the vaccine according to the Illinois COVID-19 Vaccination Plan. Oswald’s Pharmacy will be accepting walk-ins and administering vaccines either through our federal contract with Health Mart Pharmacies Group and the CDC or through our direct relationships with the DuPage County Health Department and the Illinois Department of Public Health. Check this page frequently for updates on when Oswald’s Pharmacy will have the vaccine.

Will my COVID-19 vaccine be free?

According to the CDC’s website, the vaccine will be provided to patients at no cost at this time. Healthcare providers may still charge a vaccine administration fee for actually giving you the vaccine, but this will be covered by insurance or by the Health Resources and Services Administration Provider Relief Fund for those who are uninsured or whose insurance does not cover the vaccine administration. Patients may get the vaccine from a healthcare provider regardless of if this provider would normally be considered in-network or out-of-network by their insurance plan. You will need to bring your insurance information with you wherever you get the vaccine. For people with Medicare or Medicare Advantage plans, you will need your Medicare Part B card (the red, white, and blue card).

Which COVID-19 vaccine will I get? How do the vaccines work?

Unfortunately, we do not know which vaccine Oswald’s Pharmacy will be getting from week to week until a few days before we actually receive it. There are currently 3 vaccines that are available for Emergency Use Authorization in the United States: the Pfizer-BioNTech COVID-19 vaccine, the Moderna COVID-19 vaccine, and the Janssen (Johnson & Johnson) Vaccine. Other vaccines are under development or in clinical trials before they can be granted Emergency Use Authorization in the United States.

There are currently 3 different types of COVID-19 vaccines that are in various stages of development or use: mRNA, protein subunit, and vector vaccines. Each type of vaccine works differently, but all are able to recognize and protect people from COVID-19. Both the Pfizer-BioNTech and the Moderna vaccine use mRNA technology. The Janssen vaccine is a viral vector vaccine. The CDC has more information on how these vaccines work available here.

What allergies will prevent me from getting the COVID-19 vaccines?

Experts are advising that anyone with a history of heparin-induced thrombocytopenia (HIT) should not receive the Janssen vaccine, but may receive an mRNA vaccine. We also know that certain vaccines should not be administered to anyone who has a known history of an allergic reaction (within 4 hours that caused hives, swelling, or respiratory distress) or a severe allergic reaction (such as anaphylaxis) to the following:

  • A component of a COVID-19 vaccine including either of the following:
    • Polyethylene glycol (PEG), which is found in some medications, such as laxatives and colonoscopy preps (should not get an mRNA vaccine)
    • Polysorbate, which is found in some vaccines, film-coated tablets, and IV steroids (should not get the Janssen vaccine)
  • A previous dose of a COVID-19 vaccine (depends on the vaccine)

Components of the Moderna, Pfizer-BioNTech, and Janssen (Johnson & Johnson) COVID-19 vaccines are found on their package inserts and EUAs. Neither of these vaccines contains any preservative or mercury in any form.

Here is some information about what each of the components in a vaccine does.

What are the side effects of the COVID-19 vaccines?

According to the CDC and the FDA, side effects (also called adverse reactions) are usually mild to moderate and resolve within just a few days. The most common side effects reported after the vaccines include:

  • Pain, swelling, and/or redness at the injection site
  • Fatigue (feeling very tired)
  • Headache
  • Muscle or joint pain
  • Chills
  • Fever
  • Swollen lymph nodes

Oswald’s will continue offering COVID-19 testing and other vaccinations.
