Why Cold Chain is Important to Vaccines

The arrival of the COVID-19 pandemic has challenged the world’s health system and organization. To control and prevent this virus and others of its kind, vaccination has been adopted as an effective way to protect public health.

Vaccines are chemical and biological products, which means they are sensitive to both cold and heat and must be kept in cold storage throughout the vast cold chain. The vaccine cold chain is designed to ensure vaccines remain safe and effective from the manufacturer to the point of administration.
