Flu shot questions, answered
Who should get one, when to book and what to expect after.
Ontario recommends a yearly flu shot for everyone six months and older. It is especially important for young children, adults over 65, pregnant people and anyone with a chronic condition.
When to book
Vaccine typically arrives in October. Protection takes about two weeks to build, so booking in October or November covers the peak season.
What to expect
A sore arm for a day or two is common. Some people feel tired or have a mild fever for a day. These are signs your immune system is responding, not the flu itself. The shot cannot give you the flu.
Who should wait
If you have a fever on the day, we will ask you to rebook. If you have had a serious allergic reaction to a previous flu shot, tell us before booking so the physician can advise.
