Vaccination Pros And Cons

Vaccination Pros And Cons
The immune system is our body guard, which protects it from foreign biological material. Recognizing foreign substances, it liquidates them, while “remembering” the answer to, if necessary, use it when dealing with a similar virus. In the absence of the immune system we would have been easy prey for viruses, fungi, bacteria, and helminths. Slight draft would affect most difficult infectious disease deaths. And so it happens in people with immune deficiency, immune functions are weak. And it does not matter it is innate or acquired (eg HIV infection) – the effect is the same.
