Pfizer said it would be shipping fewer CCP virus vaccine vials on Friday after finding an additional dose in each vial.
“We will meet our supply commitments according to our existing agreements — which are based on dose delivery, not vials — and we are confident in our ability to deliver 200 million doses of our vaccine to the US government by July 31” Pfizer A spokesperson for the news told the news outlets.
“In the event of limited vaccine supply amid a public health crisis, with this label change we aim to provide clarity to health care providers, reduce vaccine wastage and enable the most efficient use of the vaccine.”
Each vial contains a fixed number of doses. When vaccine administration began at the end of last year, health workers were told that each vial contained five doses. They are now being told that according to Food and Drug Administration (FDA) documents, each vial contains six doses, although the label on the vial may state that only five doses are in one vial.
Marion Gruber, director of the Office of Administration for Vaccine Research and Review, said in a letter to Pfizer earlier this month that the FDA agreed with Pfizer that “PF-BioNTTech ech 19 vaccine vial contains six 0.3 mL doses Huh.”
“Accordingly, we also include a corresponding update to the Fact Sheet for Healthcare Provider Administering Vaccine (Vaccination Provider), which clarifies that, after dilution, 0.3 mL in a vial of Pfizer-Biotech COVID-19 vaccine There are six doses of K, ”Gruber said. .
Pfizer is obliged to send 200 million doses to the United States by July 31 under agreements secured during the Trump administration.

Messenger RNA vaccines are the only two authorized for use in the United States against COVID-19, caused by the CCP (Chinese Communist Party) virus.
Patients received two shots several weeks apart.
“The safety and efficacy of a mixed product range has not been evaluated. Both doses of the series must be met with the same product, ”the CDC said in the updated guidance.
“In exceptional situations in which the first-dose vaccine product cannot be determined or is not available, any available mRNA COVID-19 vaccine has a minimum interval of 28 days between doses to complete the mRNA COVID-19 vaccination series. Can be administered on. ” It has been added.
