When Should You Get A Flu Shot?

Flu shots are an easy way to reduce your risk of catching the flu by 40 – 60%. A single flu vaccine doesn’t protect you for a lifetime, though, so you need to get one before every flu season to make sure you’re protected. So, when should you get a flu shot?

What’s the best time to get a flu shot?

The best time to get vaccinated is generally in September or October. It isn’t instantaneously effective since it takes about two weeks for your body to build up its defenses against the virus.

Once your body has produced antibodies against the current flu strain, your protection will last between four to six months. If you get your shot in September or October, it will be effective until the end of flu season, which is typically in March or April.

When is flu season?

The term ‘flu season’ is somewhat misleading since the flu virus circulates year-round, meaning that you can technically catch it in the middle of summer. That said, it’s called flu season for a reason – it will typically infect people most during the fall and winter while people spend more time indoors.

When are flu shots available?

Vaccines for the current year’s virus typically become available in early September. Most pharmacies post signs when they can start providing flu shots.

Can you get a flu shot too early or late?

Yes, you can get a flu shot too early or late. The protection that you get from a flu shot generally lasts 4 – 6 months. This means that getting vaccinated in July or August would only protect you until December, which is in the heart of flu season. Conversely, getting a flu shot in December would grant you protection until July, which is well after flu season ends.
