Immunization Cold Chain

Cold Chain

The “cold chain” is the name given to a system of people and equipment which ensures that the correct quantity  of potent vaccine reaches the women and children who need it from the point of production. The cold chain system is necessary because vaccines are delicate substances that lose potency if they are exposed to temperatures that are too warm or too cold.  High levels of immunization coverage are useless if the vaccine that was used is not potent!
