Seattle is one of four cities taking part in a new Phase One clinical trial for an updated coronavirus vaccine.

The brand-new trial will test a Moderna vaccine that's been slightly altered to better protect against the coronavirus variant first found in South Africa.

The trial is taking place at Kaiser Permanente Washington Health Research Institute and joins other trials under way in Atlanta, Nashville and Cincinnati.

The purpose of this trial is to get a first look at the safety and efficacy of this version of the vaccine.
