Second U.K. Vaccine to Combat Covid to Begin Human Testing

A second experimental Covid-19 vaccine from the U.K. is starting tests in humans this week, relying on cutting-edge technology that scientists hope will allow hundreds of millions of doses to be produced quickly.

Imperial College London’s vaccine is backed by 41 million pounds ($52 million) in U.K. funding along with another 5 million pounds of donations, including contributions from the public, the government said on Monday.
