WASHINGTON (AP) — The Trump administration says it will not work with an international cooperative effort to develop and distribute a COVID-19 vaccine because it does not want to be constrained by multilateral groups like the World Health Organization.

The decision to go it alone, first reported by The Washington Post, follows the White House’s decision in early July to pull the United States out of the WHO.

Trump claims the WHO needs reform and is heavily influenced by China.

Some nations have worked directly to secure supplies of vaccine, but others are pooling efforts to ensure success against a disease that has no geographical boundaries. More than 150 countries are setting up the COVID-19 Vaccines Global Access Facility, or COVAX.

White House spokesman Judd Deere says the U.S. will continue engaging with its global partners to defeat the virus, but will not be “constrained by multilateral organizations influenced by the corrupt World Health Organization and China.”

The WHO says even governments making deals with individual vaccine makers would benefit from joining COVAX because it would provide backup vaccines in case the ones being made through bilateral deals with manufacturers aren’t successful.
