The European Union's medicines watchdog on Wednesday approved a second coronavirus vaccine, in a relief to struggling European countries as the world reached a grim new record of 15,700 deaths in 24 hours.

The Moderna vaccine is now set to join Pfizer-BioNTech's jab for use in the 27-nation EU, where governments are grappling with soaring caseloads and slow rollouts of the vaccines already available.

"Good news for our efforts to bring more Covid-19 vaccines to Europeans!" European Commission chief Ursula von der Leyen tweeted.

Britain may have been first to begin vaccinating, but the country nevertheless returned to a full lockdown Wednesday as authorities battle to contain the alarming spread of a new coronavirus strain which appears to be more infectious.

Along with other leaders, such as France's Emmanuel Macron, German Chancellor Angela Merkel is facing accusations from critics that her government should be rolling out vaccines much faster in order to spare people from more disruption to virtually every aspect of their lives.

Concerns are also growing over the new coronavirus strains first located in Britain and South Africa, which have since been detected in dozens of other countries.

While there is no evidence so far that available vaccines will prove less effective against them, the increased transmissibility of the new variants has officials worried that their spread will outstrip the rate at which they are able to protect people.

In China, which has detected cases of both of the new strains, authorities are at loggerheads with the World Health Organization after refusing entry to a ten-strong team of experts.

The team had been due to arrive in China this week, for a hugely sensitive mission seeking clear answers on how the virus first emerged in the central city of Wuhan in late 2019 after jumping from animals to humans.

Foreign ministry spokeswoman Hua Chunying admitted it was "not just a visa issue".

"The issue of origin-tracing is incredibly complicated," she told reporters, adding that talks were continuing over "the specific date and specific arrangement" of the visit.

The spikes in caseloads around the world have disrupted the few entertainment and sports events that had managed to resume after shutdowns earlier in the pandemic.
