Seattle fishing boat outbreak suggests antibodies protect against coronavirus infection

Crew members from a Seattle-based fishing boat that experienced an explosive outbreak of the novel coronavirus have serendipitously provided what could be the first direct evidence that antibodies can protect people from reinfection. Blood samples collected before the vessel sailed in May showed that three of the 122 people aboard had robust levels of neutralizing antibodies, the type that block the virus from entering human cells, indicating they had been previously infected and recovered. All three were spared during the shipboard outbreak, which quickly spread to more than 85% of the crew. >click to read< 08:18
