When is the Best Time to Get the Flu Vaccine?

Flu season is just around the corner, and one of the most effective ways to protect yourself and your loved ones is to get a flu shot. Understanding the optimal timing for your flu shot can help you stay healthy throughout flu season. When is the best time to get vaccinated?

The flu shot is a vaccine that helps protect against the influenza virus which can cause fever, body chills, muscle aches, a sore throat, coughs and more. Getting a flu shot reduces your risk of getting the flu in the first place, but it can also make your symptoms milder if you do get sick. Vaccination also protects those around you who are most at risk of severe flu complications including babies, young children, the elderly and those with chronic health conditions. Getting your flu shot isn’t just about protecting yourself and your loved ones though; doing so also reduces the overall spread of flu viruses in your community.

So, when should you get your flu shot? The best time to get your flu shot is between September and October. This window ensures your body has enough time to build up immunity before the flu virus starts widely circulating.  It takes about 2 weeks for the flu vaccine to build up full immunity, so don’t forget to take this into account when planning for your shot. Protection lasts about 6 months before waning. Flu season typically starts in October and can last into May, so getting your shot any earlier or later might mean you aren’t protected for its entirety. Even if you miss the early fall window it’s still worthwhile to get your flu shot later rather than not at all. It will still offer protection into the springtime.

Everyone 6 months and older should get vaccinated every year. If you have an infant who is receiving their first flu shot, they will need 2 doses. If you are pregnant, have chronic health conditions or are over 65, getting your flu shot is particularly important because you are at a higher risk for complications if you become ill.

While many people don’t experience any side effects, some may experience mild symptoms like soreness in your arm or a low-grade fever. These are normal, they are a sign your immune system is working and will resolve within a few days.

Flu shots are widely and readily available. Your family physician can offer flu shots during routine appointments or through vaccination clinics. Pharmacies and local health clinics also offer the vaccine, and it’s usually covered by insurance.
