Between May and June 2022, 13 parliamentary questions (PQs) were answered regarding the UK Health Security Agency testing covid-19 variants for a pre-exposure prophylaxis antibody therapy (tixagevimab and cilgavimab), known by the brand name Evusheld. The PQs are: PQ3627; PQ2654; HL215; HL219; PQ1507; PQ3710; PQ11547; PQ14599; HL157; PQ17128; PQ15321; HL653; and PQ691.

In simplifying the technical language, the responses to these PQs incorrectly indicated that testing was ongoing. During June, the UK Health Security Agency carried out isolation and characterisation of the BA.4 omicron variant in preparation for testing it against various compounds, which could potentially have included Evusheld. However, in the PQ responses, these activities were incorrectly interpreted as testing and the language was simplified. No further testing of Evusheld including against BA.4 omicron variant took place after 26 May 2022.
The table below summarises the testing UKHSA carried out on Evusheld.
Through this WMS I am apologising for these errors and clarifying the situation with regards to the testing of Evusheld. The Department takes its responsibility for parliamentary accountability very seriously and has reviewed and amended the process for checking responses to parliamentary questions to ensure future accuracy. The table below sets out the PQ reference, the Member or peer who asked the question and the date it was published.
