GENERAL practitioners in Britain have been given new guidance allowing them to use Pfizer Inc’s extra Covid-19 vaccine doses “at their discretion”, NHS England said.
The development came a day after US regulators issued a similar guidance.
Every vial of the Pfizer/BioNTech vaccine was expected to include five doses, but GPs found it was possible to make six doses out of the vials, the Daily Telegraph newspaper reported late last Thursday (17).
The NHS confirmed that in a weekly webinar with NHS England last Thursday, clinicians were told they could use the sixth dose “at their discretion”.
The Medicines and Healthcare products Regulatory Agency (MHRA) told Reuters it was aware of the advice from NHS regarding the use of any surplus, and that the regulator had raised no objections.
The US Food and Drug Administration (FDA) had said last Wednesday (16) that extra doses from vials of Pfizer’s Covid-19 vaccine can be used, after reports of vaccine doses being thrown away by pharmacists due to labelling confusion.
The Pfizer vials are supposed to hold five doses, according to the labelling, but media reports said that pharmacists in the US had found a way for a sixth or even a seventh dose. Without clear approval from the manufacturer, however, the extra dose had to be discarded.
The Pfizer/BioNTech shot, the first Covid-19 vaccine to be approved by Western drugs regulators, is being rolled out in countries including Britain and the United States, and is expected to be approved for use in the European Union this week.
Pfizer, last Friday (18) said it had applied for an approval of its vaccine in Japan.
Britain earlier this month became the first country in the world to deploy Pfizer’s vaccine.
