In the UK, less than 2% of elderly patients hospitalised with Covid symptoms contracted the virus three weeks after receiving their first vaccine dose, a study has found, demonstrating the level of protection offered by the initial dose after 21 days.

Russia aims to reach herd immunity against the coronavirus by the autumn, president Vladimir Putin has said, urging Russians to get vaccinated.
The Kremlin has said vaccination levels are disappointing, with more than 8 million of its 144 million-strong population having received a shot. It is not clear how many of this number have received a full vaccination course.
