Flu Vaccine Q&A
This year has seen high demand for the flu vaccine across Canada and other parts of the world. Below are some of the most common questions and answers related to influenza and the vaccine, including who should get it, how it protects you, and some potential side effects that one might experience as a result.
“Who’s most at risk of developing the flu?”
The flu can affect anyone, although those who are at the highest risk of developing influenza (and potential complications) include individuals who are immunocompromised, young children, and seniors. Those who are younger (children) or older (seniors) tend to have weaker immune systems. As we grow from children into adulthood, our immune systems become stronger. However, as we age, our immune systems will also eventually weaken. As a result, it can be much more difficult for the body to fight off viruses like the flu. Individuals with certain chronic medical conditions such as heart disease, asthma, diabetes, or women who are pregnant are also at an increased risk of developing the flu.
“What are some of the complications that can occur as a result of the flu?”
While most people who develop the flu will recover by 2 weeks, there are some who may have a longer recovery period, and others who might develop complications as a result of the flu. Some of the most common complications that can occur as a result of the flu include sinus and ear infections, which would require antibiotic treatment; while more severe complications can also develop (and be potentially deadly), such as pneumonia, inflammation of the heart, brain or tissues of the muscle, organ failure, and sepsis. Individuals with chronic medical conditions, such as asthma, may notice a worsening of this condition (i.e. increased asthma attacks) when they have the flu.
“I’ve never had a flu shot before. Should I get one?”
It is up to you whether or not you get the flu vaccine, but it is currently recommended for anyone aged 6 months or older. (Children under the age of 9 years of age who have never had a flu vaccine before will need 2 doses of the vaccine.) The flu vaccine is especially important for individuals who are in the high-risk category (such as young children, seniors, women who are pregnant, those who have underlying medical conditions, as well as those who provide essential services such as doctors, nurses, paramedics, police, firefighters, etc.) In British Columbia, the flu vaccine is free to anyone who falls under any of these categories. If you’re unsure as to whether or not you’re a candidate for the flu vaccine, you can have a discussion with your local pharmacy or physician’s office.
“How will the flu vaccine help me?”
In addition to decreasing your risk of developing the flu as well as serious illness due to the flu, you also help protect others when you are vaccinated. That being said, the vaccine is not 100% effective in preventing the flu and may not provide total protection – meaning it’s still possible to develop the flu even if you’ve been vaccinated.
“Are there any side effects from the flu vaccine?”
In most cases, the side effects that someone experiences from a vaccine are typically quite mild – or all together non-existent. The most common side effects that one can expect to experience following a flu vaccine is redness, swelling or soreness at the side of the injection – which can be reduced by applying ice to the affected area, or by taking over-the-counter pain relievers, such as acetaminophen.
