Q A vaccine is a kind of medicine which is given to the human body either through injection or medicine dosage under which the body gets trained to fight with the disease which has not come in contact before. Vaccinations form a powerful immune system under which the body can fight with different types of diseases, viruses, bacteria, etc. vaccines are designed in a way to prevent the diseases rather than treating it ("Definition of Vaccination", 2020).
