The United States has disputed calls by the UN health agency to delay Covid-19 vaccine booster shots, as poorer countries battle with severe supply shortages and rising outbreaks of the virus.

The World Health Organization (WHO) on Wednesday said halting booster shots until at least the end of September would help ease the drastic inequity in vaccine distribution between rich and poor nations.
