United Nations Secretary General Antonio Guterres has renewed his call for countries to share vaccines, particularly with those that are struggling to cope with new surges and variants. 

He also renewed his call to the international community to come together to address the unprecedented challenge of COVID-19 pandemic.

"There is an urgent need for increased global solidarity to ensure that vaccines are available to everyone, everywhere," said his Spokesperson Stephane Dujarric in a regular briefing on Friday. 

Equitable access to vaccines is a prerequisite for ending the pandemic and kick-starting a strong recovery, he said.

The UN welcomed the announcement made by the Biden administration that it will be sharing millions of vaccine doses with both the COVAX facility as well as bilaterally with countries in particular need.

The Administration announced its framework for sharing at least 80 million U.S. vaccine doses globally by the end of June and the plan for the first 25 million doses.

The Biden-Harris Administration on Thursday announced an allocation plan for the first 25 million doses to be shared globally.

Approximately 7 million doses will be shared in Asia covering countries and entities including Bangladesh, India, Nepal, Pakistan, Sri Lanka, Afghanistan, Maldives, Malaysia, Philippines, Vietnam, Indonesia, Thailand, Laos, Papua New Guinea, Taiwan, and the Pacific Islands, according to White House. 

The United States will share vaccines in service of ending the pandemic globally. 

The United States will share 75% of these vaccines through COVAX. 

The United States will share at least three-quarters of its donated doses through COVAX, supplying U.S. doses to countries in need. 

"But I also want to add that the Secretary-General is extremely grateful to the United States Government for the inclusion of United Nations personnel and Member States delegates serving in the United States in its national vaccination programme, and for the generous offer to provide vaccines for United Nations frontline personnel serving in the most challenging and dangerous locations around the world," said the UN Spokesperson. 

This donation, he said, will allow the UN staff to stay and deliver critical services to vulnerable people around the world in a safe and effective manner.
