Chief Medical Advisor to President Biden, Dr Anthony Fauci, has said that the world is in a race between vaccinations and another surge of the virus. He tells Today that we should be careful not to "prematurely declare victory" despite good progress on the vaccination programme.

We also get the UK view from Professor Jeremy Brown, a member of the Joint Committee on Vaccination and Immunisation, and Professor James Naismith, director of the Rosalind Franklin Institute and professor of structural biology at Oxford University.
