FOI 22/554
24th March 2022
Dear
Thank you for your information request, dated 13th March 2022, where you asked a follow-up question to FOI 22/465 in relation to batch testing of COVID-19 vaccines:
How many batches have been rejected?
How many times has a manufacturer been notified of a failed batch?
I am pleased to provide you with the information requested.
We have obtained out of specification results for an individual test for two batches of a vaccine. The relevant manufacturer was notified on each occasion. In each case, the manufacturer withdrew their request for release of the batch and it was not necessary for NIBSC to formally reject the batch.
I hope this answers your question.
Yours sincerely
