Most people think that influenza is a mild disease. But influenza can also cause serious illness and can even cause death, especially in infants and children and can cause death in adults or the elderly.

The flu vaccine is very effective to prevent influenza disease and complications from influenza. The Centers for Disease Control and Prevention (CDC) recommends that everyone get the influenza vaccine every 6 months or 1 year.

Why do we need to make the flu vaccine every year?

Each year the influenza vaccines that recently issued, tailored to the type of virus. The virus can evolve very quickly, which means last year's influenza vaccine may not protect you from influenza this year. After vaccination, the body's immune system produces antibodies that protect the body from viruses contained in the vaccine. In addition, the levels of antibodies in the body the longer it will be getting down, therefore needed the flu vaccine each year.

The flu vaccine is given in two ways:

InjectionsVaccines are typically injected in the upper arm muscles. These vaccines contain inactivated viruses (viruses), so it will not cause you to be exposed to the flu, but it will help the body to form antibodies.

A Nasal Spray (Nasal Spray)This vaccine consists of flu viruses that live but weakened in small amounts. Recommended for children ages 2-8 years, but is not recommended for pregnant women at all.

How many types of flu vaccine?

Flu vaccines are of two types, namely the quadrivalent and trivalent:

TrivalentTrivalent vaccine contains three virus types, namely H3N2, H1N1, and influenza b.QuadrivalentQuadrivalent vaccine can protect the body from four types of the virus strain, i.e. H3N2, H1N1, influenza B strains and 2. Types of vaccines are available in the form of injections and nasal sprays.

What are the contradictions?

• Infants < 6 months.
• Have a history of allergic reactions are excellent post administering flu vaccine before. In addition, you should also be careful if you have egg allergies.
• Most flu vaccines contain small amounts of egg protein. You may still be able to do the vaccinations, but must wait at least 30 minutes up to 1 hour in the doctor's room after the shots, to see if there is an allergic reaction or not. But now it's available flu vaccines that do not contain egg protein.

How the security level and whether there are any side effects?

The flu vaccine is very safe given. The side effects of this vaccine is that may occur are headache, fever and redness or swelling at the place of injection.

You can still do the flu vaccine if only experience mild pain, such as a cough with fever with or without fever or diarrhea. However, the flu vaccine in the form of nasal sprays can not be given if you are experiencing flu and nasal congestion by mucus, as it can interfere with the absorption of the vaccine.
