Preventable diseases still pose a grave threat
Vaccination can offer great protection
Ensuring kids can grow up safe
...from many of the world’s most notorious diseases
But, it’s a huge challenge to get the vaccines to many of the people
who need them, especially in the poorest countries.
Vaccines are sensitive to heat
This can quickly render them useless
Proper cooling can protect the vaccines
But kids don’t always live in places with electricity
and refrigerators How to get the vaccine safely to them?
There is a linked system of cold storage devices, also called a "cold chain."
The vaccines can travel from major cities to the smallest, most remote community, and stay cool and safe the entire journey.
To reach children in the hottest, most remote places, we need to make the cold chain even better. People are working hard on new ideas like:
Improved solar powered refrigerators.
Creating dried vaccines
Better small mobile cooling units
Reducing weight and bulk.
Creating combined vaccines, thus reducing the size and the number of doctor visits.
A lot of work remains to be done
But the invention of cold chains has been a huge step in making sure children around the world can be vaccinated.منبع:
