The Hini vaccine side effects (also known as H1N1 vaccine) may not be as popular as it's benefits, but like any other medications this drug also has a negative story to tell as well.  In the past couple of years viral outbreak surprised the world with its widespread and created a worldwide scare among many nations.  The original source of the virus is the endemic swine flu present among pigs and has evolved to Influenza A with a subtype AH1N1 after being transmitted to humans.  The viral plaque has been around and was discovered dated back in 2005 the first outbreak was detected in Spain dated back 1918 as the virus killed 50 to 100 million population.  But the original strain was called avian influenza was thought to be one of the deadliest plaque in human history.

Luckily, today scientists have discovered drugs that will suppress the virus, eliminating the dangers it may bring.  Apparently the current vaccine still has a few cons that we all have to know about.  Apart from the break trough curing effect of the vaccine it inflict side effects to the patient taking the shot.  FDA doesn't have a concrete decision about approving the drug for human use.  More and more people are getting skeptical about signing in for a shot.  Because of the effects of the medication, the drug was just pre-approved in the time of worldwide outbreak the government is still monitoring the development about the medication.  The tests made on the drug was not enough to ensure safety for human use, but in spite of the speculations running around the health community the public doesn't have that much choice but to subject themselves to the medication rather being ruined by the dreadful disease.  The common indication of the drug's side effect includes swelling at the shot area.  Worst case of life threatening effects is very rare mostly caused by beforehand health conditions.  There are guidelines to be followed before taking the flu shot and certain conditions are to be considered in lieu to the present health condition of the patient. 

A website called CDC released a report stating that the 1976 strain of the virus vaccine caused a person to develop a severe case of Guillain-Barre Syndrome a kind of paralytic disease popularly known as GBS.  The studies indicated that the rare case ratio ranges only at 1 in every 100,000 people vaccinated.  Knowing the risk factors involved in taking the vaccine would somewhat scare us a bit as well, but the odds of getting a severe side effect is less realistic rather than risking our lives to a more dreadful fate of being infected with AH1N1 virus, but then again the decision is yours.
