Answer:
Q6.Bacteria in the large intestine also make some important substances, such as vitamin K, which plays an important role in blood clotting. These bacteria are necessary for healthy intestinal function, and some diseases and antibiotics can upset the balance between the different types of bacteria in the large intestine.
Vaccines offer a solution to this problem. They help you develop immunity without getting sick first. Vaccines are made from the same germs (or parts of them) that cause disease; for example, polio vaccine is made from polio virus. But the germs in vaccines are either killed or weakened so they won't make you sick.
