The flu vaccine is generally safe and effective, but like any medical intervention, it can cause some side effects. Most side effects are mild and temporary, such as soreness at the injection site or a low-grade fever. Understanding these side effects can help you make an informed decision about vaccination.

What Are the Common Side Effects of the Flu Vaccine?

The common side effects of the flu vaccine are usually mild and resolve on their own within a few days. These side effects are a sign that your body is building protection. Here are some of the most frequently reported side effects:

• Soreness or redness at the injection site: This is the most common side effect and usually lasts one to two days.
• Low-grade fever: Some people may experience a mild fever after vaccination.
• Muscle aches: Generalized aches can occur as your immune system responds to the vaccine.
• Headache: Some individuals report a mild headache following vaccination.

Are There Serious Side Effects of the Flu Vaccine?

Serious side effects from the flu vaccine are rare. However, it’s important to be aware of them:

• Guillain-Barré Syndrome (GBS): This is a rare neurological disorder that has been associated with the flu vaccine in very rare cases. The risk is about one or two additional cases per million people vaccinated.

How Long Do Flu Vaccine Side Effects Last?

Most flu vaccine side effects are short-lived. Common side effects like soreness, fever, and muscle aches typically resolve within 1-2 days. If side effects persist or worsen, it is advisable to contact a healthcare provider.
