Universal vaccination against COVID-19 has been threatened in the United States.
U.S. drug manufacturer Pfizer told the administration of President Donald Trump that the vaccine has been purchased. The country will not be able to provide enough additional doses of coronavirus vaccine by the end of June or July 2021. Thus, Washington may have problems with vaccination of the population: previously it was expected that most Americans will receive the drug by the late spring or early summer of 2021.
The US authorities signed an agreement with Pfizer and the German biotechnology company BioNTech in July 2020. They agreed to buy 600 million doses of coronavirus vaccine. After receiving the first 100 million doses, Washington was to pay the companies 1.95 billion dollars.
In the fall, however, it was reported that vaccine doses might not be enough. Thus, European officials warned: only part of the population of the European Union can receive the drug until 2022. Possible shortages are due to the fact that potential COVID-19 vaccines reserved by the EU may not be effective or may not be produced in sufficient quantity.
