Covid news - live: New UK Covid variant under investigation as surge testing rolled out in two more areas

Russia says it expects several European Union countries to approve the use of its Sputnik V vaccine this month, and that Moscow could provide vaccines for 50 million Europeans from June if it wins EU-wide approval, writes Ella Glover:

Four orangutans and five bonobos at a zoo in California have been given an experimental vaccine after becoming infected, National Geographic reports.

Zoo chiefs suspect the nine great apes caught the virus from a worker who had previously tested positive for the virus.

The animals’ symptoms ranged from runny noses and sporadic coughing to consistent coughing, reduced appetite, and lethargy.

They were given a vaccine developed for dogs and cats by Zoetis, a veterinary pharmaceutical company.

The apes had no adverse reactions and are doing well, say zoo officials.

Three leftover doses will soon go to bonobos and one of the zoo’s gorillas who did not get the virus.

Other US zoos have also requested doses of the vaccine for their great apes, Zoetis said.

The company is conducting trials of its vaccine in mink, with plans to apply for commercial authorisation once trials are complete, National Geographic says.

Boris Johnson has appealed for over-80s to continue observing lockdown restrictions after receiving the Covid vaccine, as a new study found that more than 40 per cent had breached them.

Less than 90 hours before the home secretary’s latest measure to deter outbound travel from the UK takes effect, there is no sign of the promised “Declaration to Travel”.

A number of travel and transport firms contacted by The Independent say they have not been briefed on the new arrangements.

A care worker put nearly two dozen vulnerable people at risk by carrying out home visits while she was suspected to have Covid-19, a tribunal has heard.

Samantha Gould, who previously worked for 1st Grade Care in Cardiff, attended a number of calls last June despite being told by her GP to self-isolate and arrange a coronavirus test after feeling unwell.

Ms Gould claimed she had been given "a verbal negative Covid test result" before making the visits and said she "kept her distance during calls and had an apron, gloves and mask".

Social Work Wales imposed an interim 18-month suspension last August over concerns Ms Gould had "showed a reckless disregard for the health and wellbeing of those in her care".

The care worker appealed against her suspension, but it was rejected.

A Catholic priest has joined legal action by other Christian leaders against the Scottish government over lockdown church closures.

Canon Tom White, of St Alphonsus RC Church in Glasgow, issued a pre-action letter to the government in February demanding it lifts lockdown restrictions forcing places of worship to close.

Separately, a group of other religious leaders launched legal proceedings in January to force the Scottish government to change tack.

Canon White has now joined the action by the other religious leaders, including representatives from the Free Church of Scotland (Continuing), the Free Church of Scotland, and a number of independent churches.

They state the closures are unlawful as they breach human rights law and the Scottish constitution.

In a major U-turn, Germany has approved AstraZeneca’s coronavirus vaccine, developed alongside the University of Oxford, for use in people over 65.
