LONDON (AP) — The World Health Organization’s Europe office said it has begun discussions with Russia to try to obtain more information about the experimental COVID-19 vaccine the country recently approved.

Last week, Russia became the first country in the world to license a coronavirus vaccine when President Vladimir Putin announced its approval. But the vaccine has not yet passed the advanced trials normally required to prove it works before being licensed, a major breach of scientific protocol. Russian officials claimed the vaccine would provide lasting immunity to COVID-19 but offered no proof.
