When Should I Get My Flu Shot?

The best way to lower your risk of getting influenza is going for a flu shot before flu season begins. We talked to Thomas Bader, M.D., vice president of medical quality at Hackensack Meridian Health about when it’s the right time to get a flu shot. Here’s what he had to say:
Timing Your Flu Shot
The Centers for Disease Control and Prevention recommends that all adults and children older than 6 months in age should get flu shots annually.
- The timing is important: September and October are generally good times to be vaccinated against flu.
- Ideally, everyone should be vaccinated by the end of October.
Cases of the flu typically peak between December and February, but the influenza virus spreads differently every year, usually beginning in November, sometimes going as late as April or May. Going for a flu shot too early – may backfire, because it may not protect you for the entire flu season.
However, it isn’t too late to get a flu shot after October, if the month comes and goes and you don’t get vaccinated. A belated flu shot offers protection for the remainder of the flu season.
Why to Get a Flu Shot Early in the Fall
It’s better to get vaccinated during early fall than later in the season, because the longer you wait, the more likely you are to be exposed to the virus without having the vaccine in your system.
Getting vaccinated doesn’t provide you with instant protection.
- Your immune system needs about two weeks to develop antibodies to the flu shot, which help to protect you from the flu.
- Roughly two weeks after you receive your flu shot, your immune system should be prepared to face off the flu for roughly four to six months.
“A flu shot may offer some protection if you’re exposed to the flu during the first few days after your vaccination, but it will be most protective after your body has time to develop antibodies,” says Dr. Bader.
You can get a flu shot at several locations, including:
- your doctor’s office
- a walk-in clinic
- at work (some employers may offer this onsite)
- a local flu shot clinic
Why to Get a Flu Shot & COVID Vaccine
COVID-19 cases are expected to continue to rise during the cold-weather months, which coincides with flu season. By getting a flu shot and COVID vaccine, you’ll lower your chances of getting severely ill from these viruses.
