In the field of epidemiology, maintaining the cold chain is crucial for several reasons:
1. Vaccine Efficacy: Vaccines must be stored within specific temperature ranges to stay effective. If the cold chain is broken, the vaccines can lose their potency, leading to reduced immunization coverage and increased risk of outbreaks. 2. Safety: Improperly stored vaccines can become unsafe, posing health risks to individuals. 3. Public Trust: Consistent and reliable vaccination programs build public confidence in health systems.
