COVID-19 Vaccination at First Choice Immediate Care – Chicago & Naperville
What is the COVID-19 Vaccine?
The COVID-19 vaccine helps your body develop immunity against the coronavirus. It reduces the risk of severe illness, hospitalization, and long-term complications.
Vaccination is one of the most effective ways to protect yourself and your community.
What the COVID-19 Vaccine is For?
The COVID-19 vaccine is designed to help the immune system recognize and fight the coronavirus.
This helps prevent severe infection, reduce the spread of the virus, and decrease the risk of serious complications.
Types of COVID-19 Vaccines Available
- mRNA Vaccines, Such as Pfizer and Moderna, teach your body to recognize and fight the virus.
- Protein Subunit Vaccines: Using harmless proteins from the virus to trigger immunity.
- Viral Vector Vaccines: Using a harmless virus to deliver important instructions to your cells.
Benefits of Getting Vaccinated
Choosing to get vaccinated offers several significant benefits:
Protection Against Severe Illness: Vaccines reduce the severity of COVID-19 if you get infected.
Lower Risk of Hospitalization: Vaccinated individuals are less likely to require hospital care.
Community Protection: Reduces the spread of the virus, helping protect those around you.
Faster Recovery: If you contract COVID-19, symptoms are usually milder, and recovery is quicker.
COVID-19 Vaccines Protect Your Health
Vaccination is one of the most effective tools for protecting your health. It helps your body build a strong defence, reducing the risk of complications, long-term effects, and severe outcomes.
Even if you’ve already had COVID-19, getting vaccinated offers protection against future infections.
What Can Happen If You Get Sick with COVID-19?
COVID-19 affects people in different ways. For some, it may cause mild symptoms, but for others, it can lead to:
- Severe respiratory issues requiring hospitalization.
- Long COVID symptoms, including fatigue, brain fog, and muscle pain.
- Increased risk for individuals with pre-existing conditions, seniors, and young children.
Vaccination significantly reduces the chances of experiencing these severe outcomes.
COVID-19 Side Effects: What to Expect
Most side effects of the COVID-19 vaccine are mild and temporary. Common side effects include:
- Pain, redness, or swelling at the injection site
- Mild fever or chills
- Fatigue or tiredness
- Headache or muscle aches
- Nausea
These side effects are expected and typically go away within a few days. They are a sign that your body is building protection.
Rare Side Effects
Serious side effects are infrequent but can include:
- Allergic reactions like rash, swelling, or breathing difficulties.
- Myocarditis (heart muscle inflammation) in some younger individuals, though very uncommon.
If you experience severe side effects, contact your healthcare provider or visit First Choice Immediate Care for urgent care.

Protection from Having Had COVID-19
If you’ve already had COVID-19, your body has developed some natural immunity. However, this protection fades over time. Vaccination boosts your immunity and offers a stronger, longer-lasting defence against the virus and its variants.
