The American company Pfizer, which is responsible for the coronavirus vaccine that has proven to be 90 percent effective, announced Wednesday that the vaccine has been produced in sufficient quantities.

However, it will soon enter a ‘complex’ distribution phase which may raise its price significantly.

According to the Washington Post, the distribution of the Pfizer vaccine in China saw significant rises in pricing due to the particular processes required in distribution.

The distribution followed a complex and costly system in terms of transportation, refrigeration and delivery across the designated points throughout China, which proved to be increasingly costly.

After the vaccine reaches vaccination centers, the vaccines must be thawed from -70 degree Celsius temperatures and injected within five days, otherwise the vaccine will become damaged, according to a Bloomberg report.

Each time, the distribution companies have to follow the same steps when transporting each batch of vaccines, which is a tedious process that will incur added expenses for companies, making the price of the vaccine high.

The Bloomberg report indicated that even the more developed countries which ordered the vaccine such as Japan, the US and the UK, will face significant obstacles in securing efficient transportation and distribution of the vaccine for logistical reasons such as truck breakdowns, power outages or sickness of transport workers.
