Meanwhile, AstraZeneca has resumed British clinical trials of its Covid-19 vaccine, one of the most advanced in development, after receiving the green light from safety watchdogs, the company said on Saturday.
The late-stage trials of the experimental vaccine, developed with researchers from the University of Oxford, were suspended this week after an illness in a study subject in Britain, casting doubts on an early rollout.
"On 6 September, the standard review process triggered a voluntary pause to vaccination across all global trials to allow review of safety data by independent committees, and international regulators," AstraZeneca said.
It added that safety reviewers had recommended to Britain's Medicines Health Regulatory Authority (MHRA) that it was safe to resume the UK trials.
The patient involved in the study had been reportedly suffering from neurological symptoms associated with a rare spinal inflammatory disorder called transverse myelitis.

Police forces across the UK on Saturday urged the public to exercise restraint and stay away from large gatherings ahead of the new "rule of six" lockdown rules that will officially come into force from Monday, amid a spike in coronavirus infections across the country.
The chairman of the organisation representing police officers across England and Wales asked people to resist any temptation for a weekend of gatherings ahead of the stricter rules restricting indoor and outdoor gatherings to just six at a time, the breach of which comes with a GBP 100 fine.
"There is a real risk some members of the public will take advantage of the current situation and treat this weekend as a party weekend ahead of the tighter restrictions being introduced on Monday," said John Apter, of the Police Federation of England and Wales.
In a series of tougher localised lockdowns, new measures banning people from mixing in homes and gardens will be imposed on Birmingham, Solihull and Sandwell from Tuesday as the R number - or the rate of infection - crossed the crucial mark of one for the first time since the lockdown was gradually eased from June.

French Prime Minister Jean Castex on Friday said his government was not planning a new nationwide lockdown to contain a resurgence in Covid-19 cases, but would implement a raft of less radical measures, Reuters reported.
France has the seventh-highest Covid-19 death toll in the world, and President Emmanuel Macron's government is trying to curb the spread of the virus while ensuring that economic and social activities such as school children's education can continue.
"The virus is with us for several more months and we must manage to live with it without letting ourselves get drawn once again into a narrative of nationwide lockdown," Castex said in a televised address.
