Poorer nations will only have enough Covid-19 vaccines for one tenth of their populations.
That's according to Amnesty International, which is calling for more companies to be allowed mass-produce the jabs.
It comes as the World Trade Organisation is to discuss a submission from South Africa and India calling for a temporary drop on copyright for vaccines.
Head of Economic and Social Justice at Amnesty, Steve Coleburn, says wealthier nations are buying most of the available supply.
"Although richer countries have boutgh enough vaccines to vaccinate their populations three times over, about 70 poorer countries will only have enough vaccines in 2021 to vaccinate 1 in 10 of their population.
"Part of the problem is that companies producing vaccines are keeping it to themselves, rather than sharing it more widely and selling only to richer countries.
"We want that to change so that everyone everywhere can benefit."
