7 things to know about the flu shot

Yep, it’s that time again. Well, technically, flu season has started earlier than usual this year. Which makes it important to consider getting the flu shot.

1. Is it really necessary?

The flu shot isn’t just for your own health - it’s actually an altruistic act of kindness and care for your community and family. When more people are vaccinated, fewer are at risk, especially those such as pregnant women and older adults who may already have a weaker immunity. The NICD says, “Although the vaccine is most effective when given before the season starts, it is not too late to get vaccinated. Protection develops about two weeks after vaccination, and annual vaccination is needed as flu viruses change over time and protection does not last from one year to the next.”

2. Who is most at risk of flu complications?

While some people experience mild symptoms, for others – such as children, pregnant women, and older adults – the flu can lead to serious health complications. It can make existing health issues worse, or lead to pneumonia, which can be life-threatening. Thankfully, the flu vaccine is considered safe for pregnant women and provides a robust level of protection for people who are most vulnerable.

3. What are the worst side-effects of the flu vaccine?

The flu vaccine is generally safe, but it can cause side-effects. The most typical of these are usually soreness, redness, or swelling at the injection site, mild fever, muscle aches, headache, fatigue, and nausea. There are rare instances where a person might have a severe allergic reaction, dizziness, or fainting, but the emphasis here is on “rare”. For the most part, the vaccine is about preventing severe illness and reducing the spread of the virus, which generally outweighs these risks.

4. How does the flu shot actually work?

According to Medirite pharmacist, Nafeesa Randeree, “The flu vaccine contains inactivated strains of actual flu viruses in circulation for the season. When our immune system is exposed to the flu vaccine, it builds antibodies in response to the antigens of the flu virus. These antibodies attack the antigens, ultimately getting rid of the virus. Because these antibodies remain in our body, when we are exposed to the actual flu, our immune system has a quicker response to fight off the virus. So, if you had the flu vaccine and you are exposed to the flu – you will typically have mild or no flu symptoms, and a much quicker recovery time!”

5. Does the vaccine make you sick?

This is one of the persistent myths around the flu vaccine. As explained by the NICD, “The vaccine does not contain the live virus, so you cannot ‘catch’ flu from the vaccine. At the time when influenza vaccine is recommended (just before the flu season), there are many other types of respiratory viruses around that can cause similar signs and symptoms to flu. There is a high chance of being infected with one of these viruses and people often – incorrectly – attribute the illness to a flu shot they’ve just had.”

6. Children can receive the flu shot

The flu vaccine is safe for children from six months and up and could even save a child's life. Vaccination is especially important for children under the age of five, as well as children who have a high-risk medical condition because they’re more likely to develop serious flu complications. Adults who are 65 and older, pregnant women, and people with chronic conditions are also at high risk of flu complications.

7. The flu shot may protect your heart health

For those with heart conditions, like heart disease, the flu vaccine can be vital. The flu can lead to serious complications like pneumonia, bronchitis, or even a heart attack, and it can make existing conditions like diabetes or asthma worse.
