The World Health Organization (WHO) has called for a suspension on booster vaccines until at least the end of September.

WHO Chief Dr Tedros Adhanom Ghebreyesus said on Tuesday that it would allow for at 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 said that there needs to be a reversal and that the majority of vaccines should go to lower-income countries.
