How to Know if You Are Having a Reaction to the Flu Shot
Can the flu shot brand you lot sick? No, doctors insist. But it does pose potential side effects, simply like any other vaccine or medicine. Your arm might be tender afterward your flu shot, or your child could develop a cough after getting a dose of the nasal flu vaccine.
"The majority of patients really don't have any side furnishings," says Sandra Kemmerly, One thousand.D., system medical director for hospital quality at Ochsner Health System in New Orleans. And when symptoms do occur, they're commonly balmy and articulate up in a day or two, she says.
So why do some people feel sick after the influenza shot while others don't? Doctors say reactions to the influenza vaccine differ from person to person and that multiple factors are likely at play.
Recollect about how people respond to the common cold. Some folks get a runny nose and become on with their lives, while others stay home with a fever or develop a coughing. It's the same with the flu shot, says Claudia Vicetti, K.D., a pediatric infectious disease specialist with UnityPoint Health in Cedar Falls, IA. "You're stimulating your body, and your allowed system may react in different ways," she says.
Experts aren't certain what to expect going into this influenza season, given that it was practically non-existent last twelvemonth due to COVID-19 safety protocols, says Richard Watkins, M.D., an infectious disease physician and a professor of internal medicine at the Northeast Ohio Medical University.
"The southern hemisphere, which is in its wintertime right now, is having some other low level influenza season. Considering the virus constantly moves between the hemispheres, it may hateful that our next flu flavor is mild too and again," says infectious disease practiced Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security.
However, he adds, "flu is unpredictable and the vaccine is the best way to foreclose information technology from impacting your life." Plus, the symptoms of flu versus the symptoms of COVID-19 are difficult to differentiate, meaning you should be vaccinated confronting both illnesses for the best protection if yous are able.
"The flu" isn't a single virus. Each flavor, a new vaccine is adult to match circulating strains. Getting a influenza vaccine can protect yous against the same or related viruses in the vaccine, but it won't cover every possible strain that a person might encounter, the CDC explains. This year's vaccine volition target the post-obit strains:
- A/Victoria/2570/2019 (H1N1) pdm09-similar virus;
- A/Cambodia/e0826360/2020 (H3N2)-like virus;
- B/Washington/02/2019- similar virus (B/Victoria lineage);
- B/Phuket/3073/2013-like virus (B/Yamagata lineage)
Even though it is not 100% constructive, getting a flu shot is the best style to protect yourself from getting sick , and tin can significantly lower your chances of winding up in the hospital. It is of import to get vaccinated before the stop of October, so your trunk has time to build upwardly immunity. The CDC says it is "more than important than ever" to protect yourself from the influenza, which can help reduce the strain on healthcare systems that are responding to the COVID-19 pandemic.
Once y'all practise go the vaccine, you may be 1 of the rare few that feels a fleck crummy after, but it shouldn't final very long. Here are the flu shot side effects to know, when y'all should and shouldn't worry, and how to feel better once side effects striking.
What are the side effects of the flu vaccine?
Whether you get a flu shot or the spray-mist blazon, side effects are more often than not no large deal. You lot may feel the following:
✔️Soreness or aching in your arm
Your arm might be sore or uncomfortable after getting the shot, only this is a skillful thing: It means your allowed arrangement is responding to the vaccine and creating antibodies, says Dr. Kemmerly. Plus, it's commonly "i solar day of discomfort," Dr. Vicetti adds, "and not everybody gets that [side effect]."
✔️Redness, pain, or swelling at the injection site
This is another good sign that your immune system is raring to go and responding to the vaccine properly, Dr. Kemmerly says. Plus, any time something breaks the pare bulwark (similar a needle), it may get red and swollen as your body reacts to information technology equally a strange object. This side effects is common and should just last a few days.
✔️Low-form fever
Experiencing a low-grade fever (below 101 degrees) after the flu shot is possible, but information technology'due south not very common. If it's whatever college than that, you may already be sick with another virus that normally circulates during flu season. A person might catch a cold, for case, or RSV (respiratory syncytial virus, a common childhood illness).
Oftentimes, people delay getting a flu shot until influenza season is in total swing, Dr. Kemmerly points out. They were already "incubating" the flu virus and "and then, lo and behold, they got the flu—just totally unrelated to the flu shot," she says.
✔️Nausea, headaches, or fatigue
These are all totally normal reactions as your trunk responds to the flu vaccine, the CDC says.
✔️Dizziness or fainting
Like any other vaccine, some people may experience dizziness or fainting after getting a flu shot, but this has much more to do with the process—getting a needle poked into your arm—than the vaccine itself, the CDC says. The arrangement emphasizes that well-nigh all vaccines receive reports of people fainting afterward, and so it'due south not unique to the flu shot lonely.
✔️Coughing or sneezing
The nasal influenza vaccine, the type your kid might get if he or she doesn't have asthma or a contempo history of wheezing, tin can cause some of the same side effects every bit the flu shot—minus the sore arm—plus some boosted ones. "There tin exist some coughing and sneezing," Dr. Kemmerly notes, "merely for the most part people feel pretty good."
✔️Sore pharynx
While the flu shot is unlikely to give you lot a sore pharynx, the CDC says that yous may experience this side effect with the nasal flu vaccine. If you happen to feel this side effect, it will usually happen soon after you get vaccinated and exist mild and short-lived.
✔️Guillan-Barré syndrome
Guillain-Barré syndrome (GBS) is a neurologic status that attacks your body'south nerve cells, in turn causing musculus weakness or paralysis in astringent cases. It got attention earlier this year after the Nutrient and Drug Administration (FDA) shared that there is an "observed increased adventure" of the condition after people were vaccinated with the Johnson & Johnson COVID-nineteen vaccine. Based on an analysis of Vaccine Adverse Issue Reporting (VAERS) data, there were 100 preliminary reports of GBS after 12.5 1000000 doses were given of the Johnson & Johnson vaccine, the FDA said. Of those, 95 were serious and required hospitalization, and one person died.
But that was for the COVID-xix vaccine—non the flu vaccine. There are people who practise develop serious side effects later getting the flu vaccine, including GBS. (These people fall on the list of people who should not get a flu shot.) The condition is extremely rare. In fact, for every one million flu shots given, only ane or two of those people will develop GBS, the CDC states. Each year, an estimated three,000 to 6,000 people develop GBS of whatever cause in the U.S.
✔️Allergic reactions
There are people who may experience an allergic reaction to the flu vaccine or its components, such equally gelatin, antibiotics, or other ingredients. The CDC says that signs of a severe allergic reaction can include difficulty breathing, wheezing, swelling around the eyes or lips, hives, high fever, and a fast heartbeat.
Life-threatening reactions to the flu shot are extremely rare. "I've been practicing for thirty years. I've never seen an anaphylactic reaction to the flu shot," says Dr. Kemmerly. Nonetheless, talk to your dr. if your side effects persist. If someone has signs of an allergic reaction after getting a flu vaccine, treat it as a medical emergency and seek aid ASAP.
⚠️ If yous've had a life-threatening allergic reaction to the influenza shot in the past, you should not get the vaccine.
If you have an egg allergy, yous tin withal get vaccinated, the CDC says, but it should be done in a controlled setting where you can be monitored. In this instance, talk to your dr. about your egg allergy then you lot tin both make an informed decision about your vaccine.
How to treat flu shot side effects
Ordinarily, any side effects you lot might go from the flu vaccine go away on their own inside a day or two—simply you don't have to tough it out if you really feel run downwardly. Endeavor these cocky-intendance measures to feel amend ASAP:
For muscle aches, headache, or flu-similar symptoms, take a pain reliever, such as Tylenol or ibuprofen.
For arm pain afterward the flu shot, apply a cool compress.
The same goes for side effects of the nasal flu vaccine. Treatment is based on a person'south symptoms, Dr. Kemmerly says. All in all, modest aches are a small price to pay for the vast protection the flu vaccine provides for both you and those around y'all.
