Covid: UK vaccines minister 'confident' over Pfizer supply

Vaccines minister Nadhim Zahawi says he is "confident" the UK's Pfizer supply "remains safe".

The EU has warned it will tighten exports of Covid vaccines produced in the bloc, amid a row with AstraZeneca over a cut in planned supplies.

Last week, AstraZeneca told the EU it was falling behind on its supply target because of production problems.
