More than 200 million coronavirus vaccine doses have been administered in at least 107 countries and territories, according to an AFP count based on official sources Saturday.

In total 201,042,149 doses had been given worldwide by 1000 GMT -- a figure that does not include the latest data from China and Russia, who have stopped making their progress public in recent days.

Some 45 per cent of the injections took places in countries belonging to the wealthy G7 club, whose members account for just 10 per cent of the global population.

Its seven countries - the US, Canada, Britain, Germany, France, Italy and Japan - promised on Friday to share doses more fairly with worse-off countries.

G7 leaders plan to more than double their total support to worldwide coronavirus vaccinations, to $7.5 billion, including through the World Health Organization-led Covax scheme.

More broadly, 92 per cent of doses worldwide have been given in countries classified by the World Bank as "high-income" or "upper-middle income", accounting for around half of global population.

Among the 29 countries the institution ranks as "low-income", only Guinea and Rwanda have begun vaccinating.

Israel is far ahead of any other country worldwide with almost half its population having received at least one vaccine dose.

One in three Israelis has received both doses needed for full protection.

Other countries to have given more than 10 per cent of their people at least one dose include Britain (25 per cent), Bahrain (16 per cent), the US (13 per cent), Chile (12 per cent), the Seychelles (43 per cent) and the Maldives (12 per cent).

Malta, which had administered just over 62,000 doses by Saturday, has also given 12 per cent of its population at least one vaccine dose.  

In absolute figures, the US has injected more people than any other nation, with 59.6 million doses.

China had reached 40.5 million by February 9, while Britain is at 17.5 million, India 10.7 million and Israel 7.1 million.
