Influenza (Flu) Vaccines: Should I Get a Flu Vaccine?
You may want to have a say in this decision, or you may simply want to follow your doctor's recommendation. Either way, this information will help you understand what your choices are so that you can talk to your doctor about them.
Influenza (Flu) Vaccines: Should I Get a Flu Vaccine?
Get the facts
Your options
- Get a flu vaccine.
- Don't get a flu vaccine.
Key points to remember
- Most people get better from influenza (flu) without problems, but the flu can be deadly. It can lead to serious health problems such as pneumonia, or it can make an existing disease worse. Every year, thousands of people end up in the hospital with other health problems from the flu.
- A flu vaccine may not always keep you from getting the seasonal flu, but it can make the symptoms milder and lower the risk of other health problems from the flu.
- A few people may not be able to get a flu vaccine. If you have a severe allergy to any part of the vaccine excluding eggs, have had a serious reaction to the vaccine in the past, have had Guillain-Barré syndrome within 6 weeks of a previous dose of flu vaccine, or are ill, be sure to tell the person who gives the vaccine.
- The Public Health Agency of Canada (PHAC) recommends that everyone age 6 months and older should get a flu vaccine. But it's most important to get one if you're at high risk for other health problems from the flu. Those at high risk include young children, pregnant women, older adults, people who have chronic diseases or weak immune systems, people who live in nursing homes or long term care centres, and indigenous people.
- If you take care of someone who is at high risk, it's a good idea to get a flu vaccine. This can lower the chance that you could spread the flu to the person you care for.
- Flu viruses change quickly, so you need to get a flu vaccine every year.
- You can't get the flu from a flu vaccine.
FAQs
The flu shot contains a killed form of several types of flu viruses. The vaccine causes your immune system to make antibodies. Then, if you are exposed to the flu later, the antibodies can attack and destroy the virus.
It takes about 2 weeks for your body to make the antibodies. So it's best to get the flu vaccine as soon as it's available. But the vaccine can still help if you get it during the flu season.
Another form of the flu vaccine may be available as a spray that you breathe in through your nose. This vaccine (such as FluMist) contains live but weak viruses. Ask your doctor what is right for you.
Flu viruses change quickly, so each year scientists make a new vaccine. To have the best chance of being protected, you need to get a flu vaccine every year. You can't get the flu from a flu vaccine.
It is recommended that adults ages 65 and older get a high-dose flu shot.footnote 2
The PHAC recommends that everyone age 6 months or older should get a flu vaccine each year.
A flu vaccine is especially important for people who are at high risk for getting other health problems from the flu. This includes:
- People who are age 65 or older.
- People who have long-term (chronic) diseases, such as heart disease, diabetes, kidney disease, and lung disease, including asthma.
- People who live in nursing homes or long-term care centres.
- People who have a weak immune system.
- People who are pregnant.
- Young children.
- Indigenous people.
The flu vaccine is also important for people who could spread the flu to others who are at high risk. This includes:
- Anyone who lives with or cares for young children.
- Anyone in close contact with a person who is at high risk for other health problems from the flu. This includes family, friends, and caregivers.
- Health care workers.
Children younger than 6 months of age and people with severe, life-threatening allergies to the flu vaccine or any part of the vaccine should not get a flu vaccine.
Talk to your doctor before getting a flu vaccine if you:
- Have a severe allergy to eggs or any part of the vaccine.
- Have had a serious reaction to the flu vaccine in the past.
- Have had Guillain-Barré syndrome within 6 weeks of a previous dose of influenza vaccine.
People who can't get a flu vaccine but are at risk from the flu may be able to take an antiviral medicine instead.
The flu vaccine may keep you from getting the seasonal flu. This can save you time (fewer days missed from work or school) and money (fewer medicine costs). The flu vaccine can also help prevent the spread of the flu to others. If you are pregnant, it can help prevent your newborn baby from getting the flu.footnote 1
If you do get the flu, your symptoms may be milder and you may be less likely to have other health problems from the flu.
The flu shot may cause mild problems, such as soreness, redness, and swelling on the arm where you got the shot. You might also have a fever, chills, muscle aches, headache, poor appetite, nausea, vomitting, stomach pain, diarrhea, and feel tired for a day or two after you get the vaccine.
The flu vaccine can't cause the flu.
The risk of a serious problem from the flu vaccine (such as a bad allergic reaction) is very small.

I am in very good health for my age. Still, I get a flu shot every year. Why take chances? I've seen too many friends end up in the hospital because they didn't take the flu seriously. I urge my kids to get it too, because you never know how nasty this year's flu strain might be.
My grandmother is in a nursing home, and I visit her every couple of weeks. I wouldn't want to risk giving her the flu, so I'm going to get the flu vaccine.
At my age, I don't see any reason to get a flu vaccine. I'm very strong, and I hardly ever get sick. I'm not worried about getting the flu.
