Flu Season: The Importance of Getting a Flu Shot

Flu season is here, and in the midst of the ongoing COVID-19 pandemic, getting a flu shot has never been more important. The flu can have severe consequences, especially when combined with the risk of COVID-19. This article will explain how the flu shot works, who should get it, and what you need to know to protect yourself and others.

What Is the Flu Shot?

The flu shot helps your body develop immunity against the seasonal flu viruses. Flu viruses change every year, which is why health experts create new vaccines each season. The vaccine triggers your immune system to produce antibodies that fight off the virus. After you receive the flu shot, it usually takes about two weeks for your body to develop full immunity.

Types of Flu Vaccines

Two main types of flu vaccines are available:

Trivalent Vaccine – Protects against two strains of Influenza A and one strain of Influenza B.
Quadrivalent Vaccine – Protects against two strains of Influenza A and two strains of Influenza B.

Who Should Get the Flu Shot?

The Centers for Disease Control and Prevention (CDC) recommends that everyone aged 6 months and older receive the flu vaccine, especially those at higher risk for complications. While the flu shot doesn’t offer 100% protection, it remains the most effective method for preventing flu and its complications.

High-Risk Groups

Certain groups of people are more vulnerable to complications from the flu. These include:

Pregnant women and new mothers (up to two weeks post-pregnancy)
Children (6 months to 5 years old)
Adults over 65
People with chronic medical conditions, such as asthma, heart disease, and diabetes
Healthcare workers and first responders

People living or working in close quarters, such as college students and military personnel, should also prioritize vaccination.

Who Should Avoid the Flu Shot?

Although flu shots are generally safe, some individuals should avoid them. These include:

Those with severe egg allergies
People who have experienced a bad reaction to the flu vaccine in the past
Individuals with Guillain-Barré syndrome (GBS) or a history of it
People with mercury allergies

If you have concerns or specific health conditions, always consult your healthcare provider.

Flu Shot Side Effects: What to Expect

For most people, flu shots are safe. However, mild side effects can occur. These may include:

Low-grade fever
Sore or swollen arm at the injection site
Headaches or chills

These side effects are generally mild and usually disappear within a few days. The flu shot cannot give you the flu, despite the misconception.

Available Flu Vaccines

Several variations of the flu shot cater to different age groups and medical needs:

High-Dose Flu Shot: Designed for individuals over 65, this vaccine contains four times the amount of antigens compared to a regular flu shot.
Intradermal Flu Shot: Available for people aged 18 to 64, this option uses smaller needles that inject just under the skin.
Nasal Spray Vaccine: Available for healthy individuals aged 2 to 49 who are afraid of needles. However, some people, including pregnant women and those with certain medical conditions, should avoid this option.

How to Access Flu Vaccines

You can easily access flu vaccines at your local pharmacy, grocery store, or clinic. In some cases, your workplace or healthcare provider may offer them as well.

Takeaway: Why You Should Get Vaccinated

The flu shot remains the best defense against the flu, particularly as it coincides with the ongoing risk of COVID-19. Although the vaccine isn’t foolproof, it can significantly reduce the severity of the illness and prevent serious complications.

Don’t wait until flu season peaks. Get your flu shot early in the fall to ensure protection throughout the season. You can schedule an appointment at your healthcare provider’s office, or check with local pharmacies for availability.ck with local pharmacies for availability.
