Covid infections continue to rise across the UK, with the latest data from the Office for National Statistics showing 1.7mn people testing positive, a 23 per cent increase on the week before.
Many other countries are experiencing similar increases, driven mainly by the recent BA.4 and BA.5 subvariants of Omicron, and hospitalisations are beginning to climb around the world.
But what are the symptoms and how worried should we be? Who will be offered a booster and when? Will vaccines adapted to Omicron be ready in time for the autumn? Will regulators co-ordinate a worldwide switch to these new jabs?
