Coronavirus: Second Vaccine Trial Begins in US

A participant gets an experimental vaccine for COVID-19 at the Center for Pharmaceutical Research in Kansas City, Missouri, Wednesday, April 8.

U.S. researchers have opened another safety test of an experimental COVID-19 vaccine, this one using a skin-deep shot instead of the usual deeper jab.

The pinch will feel no worse than a simple skin test, a researcher told the volunteer lying on an exam table in Kansas City, Missouri, on Wednesday.

The experiment, using a vaccine candidate developed by Inovio Pharmaceuticals, is part of a global hunt for much-needed protection against a virus that has triggered an economic shutdown and forced people indoors as countries try to stem the spread.

A different vaccine candidate began safety testing in people last month in Seattle, one developed by the U.S. National Institutes of Health. About two-thirds of that study's participants have gotten the first of two needed doses.

These early-stage studies are a first step to see if a vaccine appears safe enough for larger tests needed to prove whether it will protect. Even if the research goes well, it is expected to take more than a year before any vaccine could be widely available.
