Delivering vaccines to all parts of the world is a difficult and complex task, requiring a series of coordinated steps in precisely controlled environments.
This will apply to the long-awaited Corona vaccine, as its transfer to the countries of the world will require the so-called “cold chain”, which aims to control its temperature very carefully.
Experts recommend that the vaccine be stored within a certain temperature range and continuously (from the time of manufacture to the time of vaccination).
The recommended temperature varies from one vaccine to another, and if it is not followed, the vaccine loses its effectiveness, that is, its ability to protect against diseases.
For example, the Pfizer vaccine, which has been shown to be highly effective against the Corona virus, should be kept at a temperature of minus 70 degrees.
Many governments have announced their efforts to obtain Pfizer and other vaccines, as they prepare to prepare for the transport of these vaccines in a way that maintains their safety, through global cold chains.
According to the United Nations UNICEF website, the vaccine will travel by plane as “refrigerated goods.” Once it reaches a specific country, it is stored in cold rooms before being distributed to health facilities in a “refrigerated vehicle”.
The World Organization highlighted the need for “storage and transportation equipment such as cold rooms, refrigerators, freezers, and cold storage boxes to meet the performance and storage standards established by the World Health Organization.”
UNICEF has purchased nearly $ 100 million in “cold chain” equipment and services since 2018 as the organization works to obtain ongoing vaccines related to diseases that affect children, such as polio and others.
“We are working closely with partners and governments to ensure that the cold chain continues to operate effectively and efficiently in each country,” the organization stated.
Frederick McKinley Jones invented portable refrigeration and co-founded Thermo King with businessman Joe Numero.
In 1938, Numero sold his motion picture sound equipment company to Cinema Supplies Inc. to form the new entity, American Thermal Control Company, before later becoming Thermo King, in partnership with his engineer Jones.
Jones designed an air-cooled portable unit for trucks transporting perishable foods and patented it on July 12, 1940, after challenging the invention of a refrigerated truck on the Golf in 1937 by Numero partners Henry Werner, Werner co-chairman. Transportation and president of the air conditioning company. American Al Feinberg.
