- Those who have egg or mercury allergies
- Those with Guillain-Barre Syndrom (GBS)

Is It Possible to Contract the Flu Thru the Vaccine?

There are many people who are anti-flu shot. Most of them, their main concern is that they believe that you could possibly get the flu from the flu vaccine. Is it? Nope. It's not possible. Why? Well, the flu vaccine is created from inactivated or dead viruses and cannot give you the actual flu, however, that being said, the vaccine can trigger an immune response from your body so you may develop mild flu-like symptoms such as:

- Low-grade fever
- Muscle aches
- Chills
- Headaches


Pros of Flu Vaccine?

1. Best Preventative Step

According to the CDC, the first and most important step in prevent the flu is to get the annual flu vaccine. The vaccine has been shown to reduce flu related illness and complications that could result in hospitalization of even death.

2. Milder Flu Symptoms

3. Protects the Community

Getting the flu vaccination is one step towards protecting those who can't get the vaccination.


Cons of Flu Shot?

1. You May Still Catch the Flu

After you get the flu shot, it will still take about two weeks for your body to build up resistance and develop immunity to the flu virus. Meanwhile, you can potentially still catch the flu. Also, there could be an issue with the vaccine itself. The strain that the medical researchers decide to include in the vaccine may end up not being a good match for the type of virus strain that actually ends up going around during flu season.

2. Severe Allergic Reaction

There are some who may have a severe reaction to the flu vaccine or some ingredient in the vaccine shot. If you've had an allergic reaction before from taking the flu vaccine, it may be best to not get the shot and check with your healthcare provider. If you have a negative reaction to the flu vaccine, the symptoms will show up within minutes or hours. Some of these allergic symptoms may include:
    • Wheezing
    • Rash / Hives
    • Rapid Heartbeat
    • Difficulty Breathing
    • Swelling (around the eyes / mouth)
    • Fatigue or Dizziness
    • Paleness

 3. GBS

GBS, or Guillain-Barre syndrome is a rare disorder in which a person's own immune system attacks/damages their nerve cells which can cause muscle weakness and worse paralysis. Most who get this rare syndrome recover fully, but some have long-term nerve damage. If you've had GBS, check with your primary health care provider before going for a flu vaccination.



Whether you decide to get the flu shot or not is up to each individual. However, it would be wise to consider carefully the safety aspect, pros, & cons of getting the flu shot for yourself & your family members before hopping onto the flu shot bandwagon. We hope that you and your family can stay healthy & happy this flu season!
