The latest figures come after as former prime minister Gordon Brown told Sky News a failure to send unused COVID vaccines from Europe and the US to developing countries would be an act of "criminal" neglect.
He warned there has been a "lack of coordination" from western nations in helping other countries vaccinate their population.
Mr Brown said a report due to be released on Monday suggests there are approximately 240 million vaccines sitting in Europe and America that are unlikely to be used for months.
He said: "Many of them may go to waste - and that would be criminal - which could immediately be airlifted out to those countries where the level of vaccination is so low that not even the nurses and doctors are protected and certainly not the elderly and vulnerable.
"Boris Johnson promised at the G7 that he was going to vaccinate the whole world.
"He made this bold announcement that, by next year, everybody would be vaccinated who was an adult in the developing world as well as the developed world.
"But since then, so little has happened that we now face the possibility of every target being missed".
