Solution
Vaccines are dead/weakened microorganisms which provide immunity against diseases by inducing immune response of the body. Since, these microorganisms are dead/weakened, they lose their disease-causing abilities and thus pose no harm. However, if these microorganisms are not stored properly and if they are in their infective stage, they can result in widespread of the disease.
