The World Health Organisation has called for a suspension on booster vaccines until at least the end of September.
WHO Chief Dr Tedros Adhanom Ghebreyesus says it would allow for least 10% of the population in every country to be vaccinated.
A number of nations including Israel and Germany have announced plans to administer a third dose.
But Dr Tedros has warned poorer nations are falling behind.
According to the WHO, low-income countries have only been able to administer 1.5 doses for every 100 people due to a lack of supply.
Dr Tedros says there needs to be a reversal and that the majority of vaccines should go to lower income countries.
