The Washington Post wrote that the US president is expected to announce this news this week before the G7 summit in London. Biden traveled to London on Wednesday evening. The G7 summit begins on Friday and continues through Sunday.

National Security Adviser to US President Jake Sullivan told reporters on Wednesday that Biden was involved in the exchange of vaccines because it “is in the public health and strategic interests of the United States.” This is to show, he added, that “democracies are best suited to provide solutions to people all over the world”.
