Elon Musk's SpaceX conducted a study of immunity to coronavirus, more than 4.3 thousand employees of the company volunteered and took part in it. Writes about this The Wall Street Journal.

Volunteer workers undergo blood tests for antibodies to COVID-19. Together with Musk, the study was led by the heads of the company's medical division..

The authors of the work concluded that a certain threshold of antibodies may provide longer lasting protection against coronavirus. They also found that people who had COVID-19 in a milder form and with fewer symptoms produced fewer antibodies.. Accordingly, such people are less likely to receive longer lasting immunity..

The study was co-authored by Dr. Galit Alter, Senior Fellow at the Ragon Institute at the Massachusetts General Hospital, MIT and Harvard.. "

According to scientists, the results of the study will help determine who is most vulnerable to coronavirus and should be vaccinated in the first place.. For example, people without antibodies in areas with a high number of infected people may receive priority.
