However, the health authorities in Denmark have taken a decision to stop using the AstraZeneca vaccine.

Can these vaccines be used elsewhere?

In theory, yes. Countries are willing to sell or donate vaccines they no longer need.

On April 15, the Director of the World Health Organization (WHO) for Europe (WHO), Hans Kluge, suggested that Denmark was trying to do just that.

“I understand that the Danish Foreign Ministry is ready or is really looking for options to share AstraZeneca vaccines with the poorest countries,” Kluge said in a statement.

Some neighbors in Denmark offered to receive unwanted doses.

“We have fewer vaccines than people who want to be vaccinated,” said Lithuanian Prime Minister Ingrida Simonetti. “Therefore, Lithuania has expressed its willingness to receive doses of AstraZeneca as often as Denmark wishes to participate.”

There is no global record, but regional data provides an overview. Denmark, for example, responded 202,920 doses of astrazinica Figures from the European Center for Disease Prevention and Control (ECDP) appear as of April 15.

who are they, 150.671 doses It was administered 52249 remained unused.

The picture is similar across Europe, with many countries restricting AstraZeneca and Janssen vaccines to older adults.

Data from the U.S. Centers for Disease Control and Prevention also shows that many U.S. states are experiencing an overdose.

More than 20% of the vaccines purchased have yet to be administered in states such as Alabama (37%), Alaska (35%), Vermont (27%) and North Carolina (24%).

Health experts say so Unused capacity indicates that some areas may have residents unwilling to vaccinate.

Is there a plan to share the remaining vaccines?

It An international consortium aims to ensure that vaccines are shared fairly Among all nations, rich and poor. Led by Who is the With the participation of the Global Vaccine Alliance (Gavi) and the Coalition for Innovation in Epidemic Preparedness (Cepi).

By the end of 2021, Covax expects to deliver more than 2 billion doses in 190 countries.

Part of this scheme includes redistributing surplus vaccines from rich countries to the poor.

For example, the UK that bought About 450 million dosesIt promised to donate most of its “surplus” to the poorest countries. Other, wealthier nations have shown similar solidarity initiatives.

However, they faced criticism because, so far, none of them has explained exactly when you will receive the overdoses and how many intend to donate.

At least for now, rich countries are focusing on vaccinating their populations, while providing financial resources for the Covax program.

How and when can surplus vaccines be shared?

The BBC asked Gavi if he had a record of the number of surplus vaccines promised by Covax. This was his response:

“Given the context of short-term limited supply, the donated doses from oversupply countries that are equitably allocated through Covax will be an important part of the solution to get fast and fair access globally. High-end economies. Income upon sharing overdoses and we look forward to announcing our first deals soon. ”

So there are agreements to exchange surplus vaccines, but there is still no specific information about when and who is getting what, which is frustrating for many.
