Dido Harding today said the UK is in one of the leading positions worldwide to recognise and deal with new variants of the coronavirus.
And the NHS Test and Trace boss admitted to MPs that her biggest fear about Covid-19 is what we don t know , saying she was certain it would present new, unknown problems in the future.
Lady Harding was speaking to Parliament s Public Accounts Committee today to discuss the inner workings of Test & Trace.
The system, which now claims to be capable of doing more than 800,000 coronavirus swab tests every day, is one of the most comprehensive in the world, Lady Harding said.
