The US company Pfizer has reduced the number of doses of the coronavirus vaccine that it planned to deliver by the end of the year, from 100 to 50 million.
This is reported by the Wall Street Journal.
According to the source, the reason for this decision was problems in the supply chain.
“Increasing the supply of raw materials took longer than expected. It is also important to emphasize that the results of clinical trials appeared later than initially predicted,” said Amy Rose, a Pfizer spokeswoman.
It is noted that the pharmaceutical giant was faced with the fact that some raw materials used in the early stages of production did not meet the necessary standards.
At the same time, Pfizer still expects to release more than a billion doses in 2021, as originally planned.
Recall that on Wednesday it became known that the UK was the first in the world to approve for mass use a vaccine developed by Pfizer together with the German company BioNTech.
