COVID-19 vaccines advance to field trials

UK scientists immunize hundreds with coronavirus vaccine | CP 24 - Associated Press:

July 30, 2020 - "Scientists at Imperial College London say they are immunizing hundreds of people with an experimental coronavirus vaccine in an early trial after seeing no worrying safety problems in a small number vaccinated so far. Dr. Robin Shattock, a professor at the college, told The Associated Press that he and colleagues ... would now expand the trial to about 300 people, including some over age 75.

"'It's well tolerated. There aren't any side effects,' he said, adding it was still very early in the study. Shattock, who is leading the vaccine research at Imperial, said he hopes to have enough safety data to start inoculating several thousand people in October.

"Since COVID-19 infections have dropped dramatically in Britain, making it difficult to determine whether or not the vaccine works, Shattock said he and his colleagues are also looking to test their vaccine elsewhere....

"Earlier this week, the world's biggest coronavirus vaccine study started in the United States, with the first of 30,000 planned volunteers getting immunized with shots created by the U.S. National Institutes of Health and Moderna Inc. Several other vaccines made by China and by Britain's Oxford University, based on different vaccine technologies, began smaller final-stage tests in Brazil and other hard-hit countries earlier this month.

"The World Health Organization has said multiple vaccine approaches are necessary for COVID-19, noting that the usual success rate for vaccine development is about 10%. Shattock said there were numerous coronavirus vaccines now in clinical trials, and he predicted that at least some of them would prove to be effective....

"'I'm just going to hold my breath and wait to see,' he said."
