Flu Jab And The Flu Jab Side Effects

What Is The Flu Jab

flu jab side effectsThe flu jab, flu shot, or the influenza vaccine, is a vaccine designed to protect against the influenza (flu) virus. This virus is highly adaptable and variable, and quickly develops resistance to various treatments. That’s why in many cases annual vaccination is necessary.

There are three different types of influenza virus: influenza A (which can attack humans, most mammals, and birds), influenza B (which attacks humans and seals), influenza C (characteristic to humans and pigs). Usually, the seasonal flu jab contains 3 weakened influenza virus strains: influenza type A H3N2, influenza type A H1N1 and influenza type B. Depending on a potential epidemic, a more specific flu shot may be issued.

Flu Jab Side Effects

The main flu jab side effects that may occur are actually the symptoms of the flu itself. However, all these side effects should be of a rather mild intensity, without any life-threatening impact.

Some of the most common flu jab side effects are: fever, runny nose, nasal congestion and wheezing, sore throat, low muscle tone, fatigue, headaches. There were also reports of gastrointestinal problems like abdominal pain, diarrhea and vomiting. In general, fever and various aches occur 1-2 days after the administration of the vaccine and they don’t last more than a few days, in the worst cases.

The swelling of the tissue where the shot was administered can also occur as one of the flu jab side effects.

Although there is a low risk of life-threatening flu jab side effects, the most dangerous of them are of allergic nature. There is a small chance that a person inoculated with the flu jab may develop an allergic reaction to the vaccine, and symptoms are usually characterized by edema, breathing difficulties, anaphylactic shock and seizures.

Some of the flu vaccines issued for adults contain thiomersal, which is an organomercury compound, with antiseptic and antifungal action. This chemical compound is also very toxic, and even though studies have shown no conclusive toxicity related to thiomersal, due to flu shot administration, the fact that some flu vaccines contain it has generated controversy.

Lastly, if the vaccine is not prepared correctly, anyone inoculated with that particular vaccine is exposed to an infection with the influenza virus. And an infection with the virus itself increases the death rate by up to 1 to 10,000. Also an infection with flu virus increases the chance of the patient to develop the Guillain-Barré syndrome, an acute polyneuropathy that affects the peripheral nervous system.

Flu Jab Contraindications

Flu jab side effects of allergic nature may occur to patients that are also allergic to eggs. That’s because many vaccines not only the influenza vaccine are grown in embryonated eggs. Therefore, the vaccine may contain egg protein traces and induce an allergic reaction if the subject is allergic to eggs.

Vaccination with the flu jab is also not recommended to people with a history of Guillain-Barré syndrome. Also, this vaccine is not recommended to people with a weakened immune system since they just may become infected with the influenza virus.
