Some 45 percent of the injections took places in countries belonging to the wealthy G7 club, whose members account for just 10 percent of the global population.
Its seven countries, the US, Canada, Britain, Germany, France, Italy and Japan, promised 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 percent 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 percent of their people at least one dose include Britain (25 percent), Bahrain (16), the US (13), Chile (12), the Seychelles (43) and the Maldives (12).
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.
