A vaccine is a substance that can prevent a person from getting a disease. A vaccine goes into a person's body in a shot that is given by a doctor or nurse. Animals are given vaccines to protect them too. Vaccines are important because they prevent people from getting diseases caused by viruses. Viruses are difficult for doctors to treat when a person is actually sick, so preventing the disease is important.
