Many believe that once you catch the flu, your body becomes immune to it forever. While recovering from the flu does provide short-term immunity to that specific strain, the virus constantly mutates, creating new variations each season. Similarly, if your body encounters the flu virus again after you have already had the flu, you still may get sick. However, your symptoms will likely be much milder. Understanding how flu immunity works and the role of vaccines can help you stay protected from future infections.
If you think you may have the flu, it is important to seek medical care. Treatments like Tamiflu can offer significant relief from the flu, however, must be administered within the first 48 hours of infection.

Why are Back-to-back Flu Infections Possible?
Back-to-back flu infections are possible for two major reasons. Firstly, the influenza virus mutates frequently, leading to new strains that your immune system may not recognize. Secondly, although your body builds up immunity to the virus after you are sick with it the first time, this immunity is not perfect and you can still get sick from the flu virus. However, if you get the flu twice in a row, the second infection is likely to be much milder if you are infected by the same strain because your immune system is already equipped with the antibodies necessary to fight off the infection.
Can You Get the Flu After Having the Flu Shot?
You can get the flu even if you got your flu shot, but the vaccine significantly reduces the risk of severe illness. While this statement may deter you from getting your flu shot, flu shots are incredibly effective in reducing severe cases of the flu. The flu vaccine is designed to protect against the most common strains predicted for the season. However, if a different strain circulates, you may still get infected. It is important to continue to practice good hygiene practices even if you got the flu shot. This is because the vaccine doesn't provide 100% immunity, but it helps your body build defenses that can lessen the severity and duration of illness. Additionally, it takes about two weeks after vaccination for your immune system to develop full protection. You could still get sick if exposed to the flu during this period.
Who's Most at Risk for Catching the Flu Multiple Times?
Anyone can get the flu twice in a row under the right circumstances. However, individuals with weaker or less effective immune responses may be at a higher risk of getting the flu twice in one flu season. This includes young children, adults over 65, and anyone with underlying health conditions. Practicing good hygiene, getting vaccinated, and maintaining a healthy immune system can help reduce the risk of multiple flu infections.
When to Seek Medical Treatment
If you develop severe flu symptoms, such as difficulty breathing, a high fever that won't go down, or confusion, seek urgent care immediately.
