SpaceX, Elon Musk's company dedicated to space flights, has become a laboratory for Covid.
Its more than 4 thousand employees - as reported by the Wall Street Journal - made themselves available for research on immunization which was then published in the scientific journal Nature Communications.
SpaceX workers have made themselves available for a certain period of time, in recent months, to take blood samples so that researchers could analyze the content of the antibodies.
The result suggests that a certain threshold of antibodies could provide people with lasting protection against the virus but that they do not become immune.
In addition, 61% of 120 employees who contracted the coronavirus reported experiencing mild symptoms of the infection.
The published study includes data from April to June, but according to the WSJ, regular tests are still ongoing.
