We are continuously looking at ways to speed up the vital independent batch testing of Covid-19 vaccines without compromising safety.
For the COVID-19 Vaccine AstraZeneca, the independent testing performed by the National Institute for Biological Standards and Control usually takes around four days to complete.
This work is just one part of a broader set of quality and safety checks by the manufacturer which – because this is a complex biological product – cannot be sped up further.
To increase speed, our testing is done in parallel with checks by the manufacturer. The data from the manufacturer are sent to us in tranches so we can conduct interim reviews of it and complete our final review quicker.
Once we receive the manufacturer’s complete testing data, it typically takes us less than 24 hours to finalise our review of it and, provided everything meets the product specification, to issue a certificate confirming the batch is suitable in quality for use.
We keep this process under review and will take any further steps necessary to improve the timeline as long as they never compromise quality and safety.
