According to Immunization Action Coalition, the first seasonal influenza vaccine in the United States became available in 1945. The flu vaccine is recommended to provide seasonal protection against the influenza virus. The influenza virus is a highly contagious respiratory virus that's spread through person-to-person contact. The Centers for Disease Control and Prevention, or CDC, recommends that everyone 6 months and older should get a flu vaccine every year. Although the best way to prevent influenza is through annual vaccination, possible dangers may arise as a result of vaccine administration.
Injection Site Complications
You may experience injection site complications following injection with the flu vaccine. Redness, swelling, bruising or soreness of the affected area can occur. These side effects are usually temporary and last for a couple of days. Apply a cold compress to help alleviate swelling and discomfort. Acetaminophen or ibuprofen as recommended by a physician can help relieve soreness.
Allergic Reaction
If you're allergic to eggs, don't receive this vaccine. This vaccine is grown in eggs, so any leftover egg protein may cause a serious allergic reaction. If you've had an allergic reaction to the flu vaccine in the past, don't get this vaccination. Symptoms of an allergic reaction can include trouble breathing, swelling of the tongue or throat, wheezing, hives, weakness, a rapid heartbeat, or dizziness, the CDC says. If you think you're having an allergic reaction, seek emergency medical attention.
Guillain-Barre Syndrome
There may be a risk of developing Guillain Barre-Syndrome following vaccination with the flu vaccine. GBS is a rare but serious neurological disorder that causes muscle weakness and paralysis. Symptoms can begin as weakness and tingling in the lower extremities and begin to affect the lungs and upper body. According to Immunization Action Coalition, as a precaution, any person without a high risk medical condition who previously experienced GBS within six weeks of an influenza vaccination should generally not be vaccinated.
