Do you know? Vaccines contain the same germs that make the people sick. But before making the vaccines, scientists treat the germs in the lab and destroy their abilities to harm someone. That means those germs won’t be able to make you sick, even they get into your blood stream. When vaccines get into human body, it induces the immune cells to produce anibodies so that if the person comes in contact of the disease, he will not get sick. #Health
