With the increase in the spread of the Corona virus worldwide, the precedent for obtaining a Corona vaccine has become a duty for governments, especially those who suffer a constant increase in the number of infections and deaths.
But the race to get the vaccine goes through several complex challenges, as it needs to go through a special cycle, as it will go from development laboratories, to pharmaceutical factories, and then distributed through special tracks that need cooling in stages. to preserve the validity of vaccines.
Around three billion people may have difficulty obtaining the vaccine due to the lack of cooling technologies necessary to maintain the validity of the vaccine. According to a report published by the Associated Press, the poor of the nearly 8 billion people worldwide will be “the hardest hit by the Corona pandemic and they are the last who will recover from it.”
The report indicates that the poor are not only suffering from the lack of vaccine-only storage methods, as the health systems in their countries suffer, especially under the weight of the Corona pandemic, as these countries lack equipment and supplies. medical, especially refrigeration technologies.
And more than two-thirds of the world do not have the technology or refrigerated logistics equipment to maintain the cold chain for the transport and preservation of vaccines, according to a study carried out by the German logistics company DHL.
It has been estimated that transporting and delivering the vaccines around the world will require some 15,000 air cargo flights.
The issue of cooling Corona vaccines will not be easy even in the richest countries, as it will need storage degrees of minus 70 degrees Celsius, which is what logistics experts warn.
This can be a real problem in most countries in Central Asia, India, Southeast Asia, Latin America, and African countries.
In a small clinic in Burkina Faso that sees about 11,000 patients, vaccines are brought in from a hospital 40 minutes away, because they don’t have a refrigerator to store these vaccines after their refrigerator burned out last fall.
And it causes overcrowding of patients in this clinic, waiting more than 4 hours to receive regular vaccinations, and to see a doctor you also have to wait several hours.
Currently, 42 vaccines are undergoing clinical trials and a further 151 vaccines are undergoing preclinical evaluations.
The World Health Organization says it is aiming for vaccines that require refrigerated storage at temperatures of 2-8 degrees Celsius below zero.
