Before you travel abroad it is a must that you get yourself protected from every kind of diseases that may befall you. Just like the avira anti virus software that protects your computer against dangerous viruses, this is extremely important.
Immunisations help protect you from some of the diseases you may be at risk of getting on your travels. It is better if your immunisations are recorded on an official certificate which you can get from your doctor or travel health center. The purpose of this is to know what you are protected against and for your own information. You can also show this to a doctor who is treating you.
