Pfizer vaccines require regulatory approval to be administered in an emergency. In the United States, healthcare workers and people who live in nursing homes will be paid first. But the biggest challenge in the case of ticks now is their conservation. Many hospitals and advanced healthcare centers in the United States do not have complex, super cold storage facilities.
New technologies such as mRNA are being used to develop Pfizer vaccines that activate the human immune system against the virus. The vaccine requires a temperature of minus 60 degrees Celsius (minus 94 degrees Fahrenheit).
Amesh Adalja, a senior expert at the Johns Hopkins Center for Health Safety, said the cooling chain is the most challenging in vaccine supply. Many hospitals in large cities do not have the ability to store vaccines at such low temperatures.
Pfizer spokeswoman Kim Benka said the company was working closely with governments around the world, including those of the United States, Germany and Belgium, to have the vaccines delivered from their supply centers. The detailed plan is to transport the vaccine by air or road using dry ice within 10 days.
