उत्तर
Microbes of different diseases are always present in our surrounding environment and we are also prone to coming in contact with persons suffering from infectious diseases directly or indirectly. But, because of a strong immune system and the presence of antibodies against specific diseases we do not necessarily develop that disease.
The immune system of our body fights back the pathogens entering the body and most often successfully removes them. In this way, our body remains protected from diseases. Antibodies to fight pathogens may develop in a natural way or maybe produce inside the body through vaccination.
