(New York) The United States will buy an additional $ 200 million worth of vaccine made by the Pfizer-BioMtech alliance and stand up for serum against variants, Pfizer said Friday.
The new dose will bring total orders from the United States to their population of up to 500 million doses, the company said in a press release.
In detail, 110 million of these additional doses should be delivered by December 31, and 90 million of the remaining doses by April 30, 2022.
The United States placed the purchase option on the next version of the vaccine, “taking into account potential variations”, as well as new formulations of the vaccine, prescribed by health officials “if they are available and authorized”, Pfizer.
The Pfizer-Bioentech alliance confirmed in early July that the third dose of its vaccine “in the coming weeks” will increase the effectiveness of his vaccine, especially after “promoting results” in the United States and Europe.
U.S. health officials responded cautiously that “Americans who are fully immunized do not need a booster at this time,” but said “they are ready to give booster doses when science shows that they are needed.”
The spread of the Delta variant worldwide, which first appeared in India and is highly contagious since the spread of the COVID-19 pandemic, is currently causing pollution to rise sharply.
