Several countries are working on vaccines to eradicate COVID-19. It’s a worldwide effort to share information. And today the heads of state from several of America’s biggest allies took part in a virtual vaccine summit. Notably absent was the United States. The Associated Press writes:

World leaders, organizations and banks on Monday pledged 7.4 billion euros ($8 billion) for research to find a vaccine against the new coronavirus, but warned that it is just the start of an effort that must be sustained over time to beat the disease.

The funds, pledged at a video-conference summit hosted by the European Union, fell marginally short of the 7.5 billion euros being sought, but more money could arrive in coming days. Notably absent from the event was the United States, where more than 67,000 people have died, and Russia.

The Washington Post adds that Germany’s Angela Merkel, France’s Emmanuel Macron, Britain’s Boris Johnson, Japan’s Shinzo Abe, Israel’s Benjamin Netanyahu and Turkey’s Recep Erdogan all took part.

A senior Trump administration official said Monday the United States “welcomes” the efforts of the conference participants. He did not explain why the United States did not join them.

The Post adds, “Public health officials and researchers expressed surprise. “It’s the first time that I can think of where you have had a major international pledging conference for a global crisis of this kind of importance, and the U.S. is just absent,” said Jeremy Konyndyk, who worked on the Ebola response in the Obama administration.”
