Who Should Not Have The Flu Vaccine
Most adults can have the flu vaccine, but you should avoid it if you have had a serious allergic reaction to a flu vaccine in the past.
You may be at risk of an allergic reaction to the flu vaccine injection if you have an egg allergy. This is because some flu vaccines are made using eggs.
Ask a GP or pharmacist for a low-egg or egg-free vaccine.
If you’re ill with a high temperature, it’s best to wait until you’re better before having the flu vaccine.
Common Side Effects Of The Flu Vaccine
Some people don’t experience any side effects after a flu jab. But the most common reactions are:
- a sore arm, or pain, itching, or redness at the injection site
- aches and pains
- feeling feverish, tired, or unwell
These are normal responses to the vaccine.
You may be asked to wait 15 to 20 minutes after your vaccination so that treatment can be given quickly if a very rare, severe allergic reaction occurs. Many people aged 13 years and older will only need to wait 5minutes. Children under 13 years will need to wait 20 minutes.
Allergic responses are extremely rare.
Shoulder Injury Related To Vaccine Administration And Other Injection Site Events
Shoulder injury related to vaccine administration is a preventable occurrence caused by the injection of a vaccine into the shoulder capsule rather than the deltoid muscle. As a result, inflammation of the shoulder structures causes patients to experience pain, a decreased range of motion, and a decreased quality of life. Physicians can mitigate SIRVA and other injection site events by refreshing their knowledge of and adopting proper landmarking and injection technique. Awareness is crucial to identifying patients who are displaying signs of this injury so they can access treatment in a timely manner.

Flu Vaccine And Coronavirus
Flu vaccination is important because:
- more people are likely to get flu this winter as fewer people will have built up natural immunity to it during the COVID-19 pandemic
- if you get flu and COVID-19 at the same time, research shows you’re more likely to be seriously ill
- getting vaccinated against flu and COVID-19 will provide protection for you and those around you for both these serious illnesses
If you’ve had COVID-19, it’s safe to have the flu vaccine. It will still be effective at helping to prevent flu.
Who Should Be Immunised Against Flu
Immunisation for the flu is recommended for everyone aged 6 months and over.
Some people are more at risk of complications from influenza and are eligible for free vaccination.
People with an underlying medical condition or reduced immunity are most at risk and should be immunised against influenza. They include:
- anyone aged 65 years and older
- pregnant women
- all Aboriginal and Torres Strait Islander people aged from 6 months and over
- people 6 months or older with:
Some workplaces run annual immunisation programs for staff.

The Vaccine Cant Give You Flu
You cant get the flu from the flu jab. The flu vaccine doesnt contain any live viruses so it cant give you flu.
It takes up to twoweeks for the body to develop protection against flu.If youve been infected with the flu before or soon after having the vaccine, you can still get the flu. If these symptoms continue or get worse, talk to your healthcare provider or callHealthline on
Why Is The Shot Given In Your Arm
Muscle tissue, like that found in your arm, has a high concentration of blood vessels. This allows the cells of your immune system to effectively access and process the contents of the vaccine.

What Arm Should I Get My Flu Shot In
Dr. Mora recommends getting the flu shot in the arm you use the least. “That way if you are writing or doing day-to-day activities, you’re not aggravating the muscle even more,” she says.Some other ways to reduce pain include trying not to tense your arm while you’re being vaccinated and moving your arm after vaccination to increase blood flow and help disperse the vaccine throughout the area.
Flu Shot Vs Covid Vaccines
Since the COVID-19 vaccines started rolling out in December 2020, over 67% of the U.S. population have received at least one dose. Some people reported side effects of the COVID shot that kept them home in bed for a day or two.
While the COVID vaccine does not protect against the flu the side effects of the vaccines are similar. A sore arm where the shot was given, fatigue, fever, and body aches, can happen with either vaccine.
It’s also completely safe to get both shots at the same time. The Centers for Disease Control and Prevention has given the green light for people to get both a COVID-19 vaccine and the flu shot, along with other vaccines that they might be due for, at the same visit.
According to the CDC, the immune response that is triggered after you get a vaccine is usually the same whether you get one shot at a time or multiple shots at once.

What Should I Know About The 2021
For starters, its important to know that its highly recommended that you get vaccinated against the flu even though last years flu season was mild, thanks, in large part, to many people masking, staying indoors, and taking other preventive measures to avoid the spread of COVID-19.
A minimal flu season last year doesnt mean were in the clear this year. In fact, weve already seen flu outbreaks this flu season, such as the massive outbreak at the University of Michigan campus. Dr. Agarwal says theres a possibility that outbreaks will continue throughout the flu season as people loosen up on illness-reducing behaviors like wearing face masks. And its important to remember that some people do end up with complications from the flu.
Flu viruses are always changing, so flu vaccine formulas are reviewed every year to best protect people against the viruses that are predicted to cause the most illness, according to the CDC. All of the vaccines available for the 2021-2022 flu season, whether theyre via nasal or needle administration, protect against the same four flu viruses circulating heavily right now.
According to the CDC, one vaccine isnt any better than the other, but if you have any questions about whether one might be best for you, then its always safest to talk to your doctor.
Why Does Soreness Last For A Few Days
Your body’s process of reacting to the vaccine can take several days. which is why you may end up having arm soreness for that time, Holmes says. The pain from the inflammation caused by the shot itself also takes time to go away.
Think of inflammation as the pain you get after you hurt your knee or ankle that kind of pain can take a few days to resolve, Valdez say. She also adds that the small injury to your muscle from the needle also takes time to heal. The site of injection is starting block of the immune response. A lot is going on in that one site.

Can You Prevent Arm Pain Before Your Flu Vaccine
There aren’t really any good hacks to lower your risk of arm pain ahead of time, Jamie Alan, PhD, associate professor of pharmacology at Michigan State University, tells Health. “You can pre-medicate with something like acetaminophen or ibuprofen, but there is some evidence that taking these medications may make vaccinations less effective,” she says.
The Centers for Disease Control and Prevention backs this up: In listing out considerations to take before getting your COVID-19 vaccine specifically, the CDC says it’s “not recommended” to take over-the-counter medication like ibuprofen, aspirin, or acetaminophen before you get the vaccine to prevent side effects. That’s because “it is not known how these medications might affect how well the vaccine works,” the CDC says.
Basically, without a ton of conclusive evidence on how, if, or why pain relievers may impact vaccine effectiveness, you’ll probably want to err on the side of caution and skip them before your shot .
Another tip: Alan says it’s a good idea to relax your arm “as much as possible” before your shot to keep your muscles from tensing and prevent the needle from having to work a little harder to get in there.
And, while this won’t necessarily change whether you’re sore or not after, it’s generally a good idea to get your vaccine in your non-dominant arm, Dr. Schaffner says. “If you do get a sore arm, it will interfere less with your function,” he says. “You can write more easily and do the usual things.”
Importance Of Needle Length
Needle length should be chosen based on the body habitus and weight of the patient. A needle that is too long can penetrate the deltoid muscle, hitting the bone. Although patients will not feel their bones being hit, the vaccine might not fully absorb into the muscle, leading to a reduced immune response. Furthermore, if the needle is too short the vaccine might be administered subcutaneously, which might result in decreased immune response and the development of nodules or cellulitis.
The efficacy of vaccines administered outside the proper injection site is not guaranteed or quantified. In particular, a 16-mm needle should be chosen for patients weighing less than 60 kg and a 25-mm needle is appropriate for patients weighing 60 to 70 kg . Women weighing 70 to 90 kg or men weighing 70 to 118 kg should receive injections with either a 25-mm or 38-mm needle. A 38-mm needle is necessary for women weighing more than 90 kg and men weighing more than 118 kg . All health care professionals who provide injections should make individualized needle length selection part of their injection administration routine.

Why Does Your Arm Hurt After A Flu Shot Here’s How Experts Explain It
It’s not only because someone just jabbed it with a needle.
Getting your annual flu shot is the first and most important step in protecting yourself and your loved ones against an unavoidable flu season. For the most part, that flu shot comes with only minor side effectsfatigue, headache or muscle aches, a mild feverand they’re much more manageable than getting the flu itself.
Another side effect from the flu vaccinearguably the most common oneis pain, swelling, or redness where the shot was given. On the surface, it makes sense: Of course you’ll have arm pain if you get a flu shot in your arm. But is your arm really supposed to be that sore after a tiny needle delivers the vaccine?
Turns out, there’s a little more to that localized arm pain, according to experts. Here’s why it tends to happen, and what you can do to lessen the discomfort, both before and after the jab.
Why A Little Bit Of Arm Pain Is Necessary Each Year
Even if you received a flu shot in a previous year, you should still protect yourself with a new vaccination this year. This is because the vaccine is developed based on the specific flu strains scientists expect to be the most dangerous this year. Doctors recommend getting vaccinated in fall, but it is never too late to get the flu shot. Getting it late is better than not at all.

So Why Do Some Shots Hurt Worse Than Others
The short answer is that were not 100 percent sure. The long answer is, well, longer.
Apart from the typical variation in immune responses and pain tolerances from person to person, it seems like some of the difference has to do with how much of a reaction the vaccine produces. Zimmerman explains that some very simple proteins, like hepatitis B, dont cause a huge inflammatory response. Others, like the live varicella vaccine, cause a much bigger ruckus within your immune system.
And then there are the adjuvants. Thats just a term for the additives in some vaccines that trigger your immune system to produce an even larger response. Generally speaking, the bigger the response, the better the immunity. Not every shot contains adjuvants because some viruses, even those that are weakened or inactivated, produce a strong enough reaction on their own. The measles/mumps/rubella shot doesnt have any, nor do the shots for chickenpox, polio, or rotavirus. Even certain flu shots come sans-adjuvants. But for those viruses that do need a boost, these additives can really help. And that means they can leave you feeling extra sore.
Can You Get A Flu Shot If Youre Sick
It depends. The general guidance is it depends on how sick you are, says Donald Ford, MD, MBA, Chairman of the Department of Family Medicine at Cleveland Clinic. If you have a mild illness or a cold what we normally think of a routine viral infection theres absolutely no reason why you cant go ahead and get your flu shot, which is protection against a more severe viral infection.
However, if you have a fever which for adults is classified as a temperature over 100.4° F or are otherwise feeling unlike yourself, Dr. Ford recommends rescheduling for another day.
The temperature is one marker, he says. If youre sick enough that youre staying home from work, if youre having trouble keeping food down or staying hydrated, those would be all reasons to at least postpone it.

What Are The Symptoms Of Sirvaand How Is It Treated
While dull muscle ache pain after a vaccine injection is common, it usually disappears on its own with days. With SIRVA, on the other hand, an individual will usually start feeling pain within 48 hours of the vaccination, and doesnt improve.
“In patients who experience SIRVA, months may pass by, and patients will still complain of increasing pain, weakness, and impaired mobility in the injected arm. Simple actions like lifting your arm to brush your teeth can cause pain,” said Kelly Grindrod, a professor in the School of Pharmacy at Waterloo and one of the authors of the 2018 study.
People experiencing these symptoms should talk to their doctor. “It’s important that we learn to recognize these signs of SIRVA so that we can access appropriate treatment,” Grindrod points out.
In order to diagnose SIRVA, an ultrasound scan is needed, which can also determine the level and type of damage. Inflammation reducing oral medications and corticosteroid injections to the shoulder are common treatments for SIRVA, and additionally, physiotherapy may be recommended.
Special Consideration Regarding Egg Allergy
People with egg allergies can receive any licensed, recommended age-appropriate influenza vaccine that is otherwise appropriate. People who have a history of severe egg allergy should be vaccinated in a medical setting, supervised by a health care provider who is able to recognize and manage severe allergic reactions. Two completely egg-free flu vaccine options are available: quadrivalent recombinant vaccine and quadrivalent cell-based vaccine.

How Is The Flu Vaccine Given
- Kids younger than 9 years old will get two doses of flu vaccine, spaced at least 1 month apart, if they’ve had fewer than two doses before July 2019. This includes kids who are getting the flu vaccine for the first time.
- Those younger than 9 who had at least two doses of flu vaccine will only need one dose.
- Kids older than 9 need only one dose of the vaccine.

Why Does My Arm Hurt The Day After I Get My Flu Shot
And why does it go in your arm instead of your butt?
BySara Chodosh | Published Nov 14, 2017 6:00 PM
Needles usually hurt. That bit makes sense. Flu shots are painful because someone is jabbing a pointed bit of metal into your arm and forcing fluid into your body. But why does it sometimes hurt more the next day? And while were at it, why does the shot even go in the arm? Didnt doctors and nurses use to jab those needles into our buttcheeks??

So Why Does Sirva Happen
Dr. Donohue explains that doctors and nurses are properly trained in landmarking, or determining where a vaccine should be given in the arm and using the proper needle length. When a needle is injected too deep the deltoid muscle can be penetrated and structures within the shoulder can be damaged such as the rotator cuff or joint capsule, he explains. In very rare cases the axillary or radial nerves in the upper arm could be injured.
According to the 2012 case report, SIRVA is due to an inflammatory effect from vaccine administration into the subdeltoid bursa, or a fluid-filled sac located under the deltoid muscle in the shoulder joint.
A 2018 study published in the Canadian Pharmacists Journal, specified that it occurs when an injection is administered too high in the arm, and the vaccine is delivered to the shoulder capsule instead of the deltoid muscle.
