COVID-19: Should countries send vaccines abroad instead of giving booster jabs?

As the UK starts rolling out booster jabs, health experts have raised concerns about diverting resources from developing countries with much lower vaccination rates. Sky News analysis has found two-thirds of countries have vaccinated less than 40% of their population - the target that WHO set for the end of 2021. The UK is one of a number of developed countries rolling out a third dose to over-50s and vulnerable groups from this week in order to bolster protection against the virus. But the WHO's director general has called for the suspension of boosters until the 'critical milestone' of 40% vaccine coverage has been reached across all countries.
