NEW YORK, April 15 (CNA) - A COVID-19 vaccine may be the only thing that can bring back "normalcy", United Nations (UN) Secretary-General Antonio Guterres said on Wednesday (Apr 15).

"A safe and effective vaccine may be the only tool that can return the world to a sense of 'normalcy', saving millions of lives and countless trillions of dollars," he added during a video conference with the African countries that are members of the United Nations.

He called for its accelerated development and accessibility to all, adding it must have a "universal global benefit" and "allow us to control the pandemic".

"We need an ambitious effort to ensure that international stakeholders operate through a harmonised, integrated and leveraged approach to maximise the speed and scale needed for the universal deployment of such a vaccine by the end of 2020," he added.

Guterres said his appeal on Mar 25 for US$2 billion in donations for a comprehensive UN humanitarian response to the pandemic had so far raised about 20 per cent of that amount.

Through the World Health Organization, the United Nations has been able to equip 47 African countries with COVID-19 tests, he said.

The UN chief also praised the efforts of several African governments to mitigate the consequences of the pandemic.

He cited Uganda, which has given businesses more time to file their tax returns; Namibia, which provides emergency income for workers who have lost their jobs; Cape Verde, which provides food aid; and Egypt, which has reduced taxation on industries.
