What you need to know about flu vaccination if you have cancer

As flu season approaches, it’s important to understand the need to get vaccinated for influenza, or flu. Indications are it could be a different flu season than what the U.S. experienced the past two years. If you have cancer, it’s especially important that you protect yourself from the flu.

Flu is a viral infection that attacks your respiratory system, including your nose, throat and lungs. At first, the flu may seem like a common cold with a runny nose, sneezing and sore throat. But colds usually develop slowly; whereas, the flu tends to come on suddenly. Although a cold can be a bother, you usually feel much worse with the flu.

For most people, the flu resolves on its own. But sometimes the flu and its complications can be deadly. People at higher risk of developing flu complications include young children, pregnant women and those two weeks postpartum, people over 65, people with weakened immune systems and some chronic illnesses, and people who are obese.
