Five Americans are out of the hospital and back in quarantine at a Northern California military base. They had shown symptoms of coronavirus after evacuating from China last week, but the CDC cleared them today. They rejoined over 200 other evacuees being housed in isolation at Travis Air Force Base. The quarantine at a different base in Southern California was lifted yesterday, and those people were allowed to return to their homes after being cleared.
At the same time, the race is on to get a coronavirus vaccine on the market. Inovio Pharmaceuticals in San Diego created it in just three hours after Chinese scientists released the genetic sequence last month. The vaccine has already been tested on mice and guinea pigs. Human trials are up next. The hope is to have it ready by early summer.
