Top 10 Flu Shot Questions

  1. When is flu season?
    While the flu viruses can be detected year-round, we see spikes in the fall and winter months and therefore refer to these months as ‘flu season’. The exact timeframe is different year-over-year, though it’s common to see increased cases beginning in October and continuing as late as May, with peaks between December and February.
  2. How long does the flu shot last?
    The length of time that the flu vaccine provides protection against the flu depends on the individual, though it lasts between four to six months for many. With cases starting to rise as early as October, it’s best to get your flu shot when flu vaccination clinics are available and widespread in October. However, if you’re not able to get vaccinated until November or later, it’s still highly recommended by the Center for Disease Control and Prevention (CDC) and many medical professionals as the most common peaks occur between December and February with activity continuing into May.
  3. Can you get the flu from the flu shot?
    No, the flu vaccine cannot cause the flu. While you can’t get the flu from the vaccine, some people report mild side effects.
  4. What side effects should I expect after the flu shot?
    Some people report mild side effects after receiving the flu vaccination. The most common are soreness, redness, tenderness or swelling where the shot was given. Other side effects could include a low-grade fever, headache, or muscle aches.

    For the nasal mist flu vaccine, some reported side effects include nasal congestion, runny nose, sore throat, and cough. Side effects are generally mild and last one to two days, while the flu can be severe and last up to two weeks.

  5. Why is the flu shot less effective some years?
    According to the CDC, a flu shot reduces your risk of catching the flu by 40-60%. Varying effectiveness is seen due to two primary factors. The first is the characteristics of the person including age and general health. The second is how well the vaccine matches the flu viruses that are spreading in any given community.

    If you do catch the flu after getting your shot, your symptoms should be milder than they would have been without the vaccine.

  6. I am young and healthy. Why would I get the flu shot?
    To protect our health care resources

    The possibility of overwhelming our health care system has been a concern since the pandemic began. Flu season significantly adds to that concern. Both the flu and COVID-19 can have similar symptoms. Both viruses can also cause lung issues and other serious health problems that may require hospitalization. Getting your flu shot significantly lowers your chance of needing flu-related testing or hospital care.

    To protect our loved ones, neighbors, and communities
    When it comes to preventing infection, it’s not just about you! “When I get vaccinated for the flu, I’m doing more than protecting myself,” says Dr. Plavin. “I’m also protecting my kids, older Vermonters, pregnant people—all those who are at high risk of complications and death. I get vaccinated to protect others just like I wear a mask to protect others.”

  7. Is the flu shot free?
    Flu shots are generally free under most health care plans, and always free for Blue Cross and Blue Shield of Vermont members. It’s important to remember that while the flu shot itself is free, you may owe deductible, co-payment, or co-insurance for visits to your doctor’s office.

  8. Is it any more important to get the flu shot with COVID-19?
    Getting a flu shot is a good idea every year. This year, because of the continued threat of COVID-19, every Vermonter should make the flu shot a top priority. 

    “It is extremely important for Vermonters to get a flu shot this year,” says Dr. Plavin. “The physical safety measures we’re all taking to protect against COVID-19 will help to slow down the spread of the flu, but the flu vaccine is the most effective way to prevent flu-related illness.”

  9. Who should get the flu shot?
    Everyone ages six months and older should get the flu shot every season. Your doctor can tell you if you fit into one of the very rare exceptions.

  10.  Is it safe to get the flu shot and COVID vaccine or booster at the same time?
    The CDC shared that the COVID-19 vaccine may be given without regard to the timing of any other vaccine. Therefore, the COVID-19 vaccine can be given at the same time as a flu vaccine, or any other routine vaccine. It can also be given on a different day without any waiting period. 

    You can get a booster shot for COVID-19 at the same time as you get a flu shot, or the day before, or the day after, or at any other time.
