Yes, UnitedHealthcare typically covers the flu shot at 100% with no copay or cost-sharing when received from an in-network provider, as of 2026. Coverage details may vary by specific plan variant, so always check your policy documents or call customer service to confirm.
What does the COVID-19 vaccine do in your body?
The COVID-19 vaccine teaches your immune system how to recognize and fight SARS-CoV-2, the virus that causes COVID-19.
Here’s what happens after you get the shot: your immune system kicks into gear, producing antibodies and immune cells designed to attack the real virus if you’re exposed later. Honestly, this is the best way to prime your body for battle without actually getting sick. You might feel some temporary side effects afterward—like a sore arm or mild fever—which just means your immune system’s working hard to build protection.
Can you still get COVID-19 after vaccine?
Yes, you can still get COVID-19 after being vaccinated, though the risk is much lower.
These are called “breakthrough infections,” and they’re usually milder than if you hadn’t been vaccinated at all. No vaccine is perfect, but getting vaccinated slashes your chances of ending up in the hospital or dealing with severe symptoms.
How does the COVID-19 vaccine boost your immune system?
The vaccine stimulates your immune system to produce antibodies and memory cells without causing illness.
Think of it like a training exercise for your immune system. It learns to recognize the virus and mount a defense—just like it does after catching the flu or chickenpox—but without the actual illness. Pretty clever, right?
Do COVID-19 vaccines reduce the risk of serious illness?
Yes, even as effectiveness against infection wanes over time, COVID-19 vaccines continue to strongly reduce the risk of hospitalization and death.
Protection against infection fades faster in people 65 and older, which is why boosters are so important. Bottom line? Getting vaccinated is still the smartest way to dodge severe outcomes, no matter the variant.
Does the pneumonia vaccine provide any protection against COVID-19?
No, the pneumonia vaccine (PPSV23 or PCV13) does not protect against COVID-19.
It only guards against certain bacterial pneumonias, like those caused by Streptococcus pneumoniae. That said, if you’re over 65 or have chronic health issues, getting both vaccines is a smart move for overall protection.
Is it safe to take Tylenol or Ibuprofen before a COVID-19 vaccine?
It is not routinely recommended to take Tylenol (acetaminophen) or ibuprofen before the COVID-19 vaccine.
Experts aren’t totally sure how these meds might mess with your immune response, so they suggest skipping them unless your doctor says it’s okay.
Is it safe to take pain relievers before getting the COVID-19 vaccine?
It’s best to avoid over-the-counter pain relievers before your COVID-19 shot, but safe to take them afterward if needed.
If you take pain relievers regularly—like for arthritis—keep doing so as prescribed. Just don’t add extra doses before your shot unless your healthcare provider gives the green light.
Can I take an antihistamine before getting a COVID-19 vaccine?
Yes, taking an antihistamine like Benadryl before the vaccine is generally safe if you have allergies.
Antihistamines won’t interfere with your vaccine response, so feel free to take them if that’s part of your usual routine. Just don’t start anything new without checking with your doctor first.
For most people, it is not recommended to avoid, discontinue, or delay medications that you are routinely taking for prevention or treatment of other medical conditions around the time of COVID-19 vaccination.
Unless your doctor advises otherwise, continue taking your regular medications as prescribed before and after vaccination.
That includes everything from blood pressure meds to insulin to inhalers. Only make changes under medical supervision—otherwise, you risk throwing your treatment off track.
Yes. All currently authorized and recommended COVID-19 vaccines are safe and effective, and CDC does not recommend one vaccine over another. The most important decision is to get a COVID-19 vaccination as soon as possible.
All authorized COVID-19 vaccines available in 2026 are considered safe and effective by the CDC.
Getting vaccinated cuts your risk of severe illness and helps protect the people around you. If you’re unsure which vaccine to pick, chat with your healthcare provider—they can help you decide.
Sometimes after vaccination, the process of building immunity can cause symptoms, such as fever. These symptoms are normal and are a sign that the body is building immunity.
Mild symptoms like fever or fatigue after vaccination are normal and indicate your immune system is responding.
These side effects usually fade within 1–3 days. If they stick around longer or get really bad, reach out to a healthcare provider for advice.
