Flu Shot: What to Expect After Getting Vaccinated

 

A flu vaccine, otherwise known as a flu shot, is the most effective way to prevent or reduce infection by flu viruses. This vaccine was created in the 1930s as a solution for the flu virus infection that has affected millions of people worldwide every year.

Flu is one of the most contagious diseases in the world. It can easily spread by coughing, sneezing or even touching surfaces that contains viruses. Anyone can be infected by this disease, young or old, female or male, rich or poor.

The World Health Organization (WHO) is still collaborating with many scientists around the world in developing the most effective vaccines that can prevent flu infections. Meanwhile, the current flu vaccine is considered to be effective and has reduced the rates of flu virus infections over the years. This is why children and adults aged 60 years old or older who have the risk of developing complications due to flu should be given flu shots every year.

If you are about to receive the flu vaccine, you must know that certain people are bound to feel something after receiving their flu shot. This is not to scare you; these are the things that you may expect after having a flu shot.
