Pfizer said Friday it will send fewer vials of CCP virus vaccines after an extra dose in each vial.
“We will meet our offer obligations in accordance with our existing agreements – which are based on the delivery of doses, not vials – and we are confident in our ability to deliver 200 million doses of our vaccine to the US government by 31 July. “Pfizer spokesman told newspapers.
“In a situation of limited vaccine supply in the midst of a public health crisis, our intention with this label change is to provide healthcare providers with clarity, minimize vaccine wastage and use the vaccine effectively.”
Each vial contains a certain number of doses. When the administration of vaccines began late last year, health professionals were told that each vial contained five doses. They are now told that each vial contains six doses, according to documents from the Food and Drug Administration (FDA), although on the labels on the vials it may appear that only five doses are in a vial.
Marion Gruber, director of the administration’s office for vaccination and vaccine research, said in a letter to Pfizer earlier this month that the FDA agrees with Pfizer ‘that there are six 0.3 ml doses in a bottle of Pfizer-BioNTech COVID -19 vaccine. ‘
“Consequently, we agree with the related updates of the facts for healthcare providers administering vaccine (vaccination providers) that make it clear that one vial of Pfizer-BioNTech COVID-19 vaccine contains six 0.3 ml doses after dilution,” Gruber said.
Pfizer is required to ship 200 million doses to the United States by July 31 under agreements reached during the Trump administration.
The Centers for Disease Control and Prevention (CDC) meanwhile said on Friday that the vaccines Pfizer and Moderna could not be exchanged.
The messenger RNA vaccines are the only two that may be used in the United States against COVID-19, the disease caused by the CCP virus (Chinese Communist Party).
Patients receive two shots that are several weeks apart.
‘The safety and effectiveness of a range of blended products have not been evaluated. Both doses of the series must be completed with the same product, ”the CDC said in an updated guide.
“In exceptional situations where the first dose of vaccine product cannot be determined or is no longer available, any available mRNA COVID-19 vaccine may be administered with a minimum interval of 28 days between doses to complete the mRNA COVID-19 vaccination series. complete, ”it added.
