Billionaire Elon Musk became co-author of a study on Covid-19 where he joined researchers to track the coronavirus infection in 4,000 SpaceX workers who came forward as volunteers Results suggest that only a certain threshold of antibodies can provide people with lasting protection against the virus

To monitor the prevalence of the virus among SpaceX employees nationwide, “Musk and the rocket company’s senior medical executive worked with doctors and university researchers to develop an antibody screening program More than 4,000 SpaceX employees have volunteered for monthly blood tests, ”Wall Street Journal reports

The results suggest that people who had fewer symptoms of milder Covid-19 generated fewer antibodies and were therefore less likely to reach the threshold of long-term immunity

The immune decision to generate a robust or weak response may occur at the time of host-pathogen interaction, depending on the level of viral challenge or inflammatory signals

“A low level challenge may cause only weak and malfunctioning antibodies Conversely, a high load challenge can lead to the generation of a potent and functionally robust immune response, programmed to respond aggressively upon re-encounter with the pathogen, “the study says. published in the journal Nature Communications

The results noted that unlike natural asymptomatic / mild infection, SARS-CoV-2 vaccines appear to induce robust immune responses

Researchers have observed a few cases of reinfection in workers who previously had low antibody counts

“People can have antibodies, but that doesn’t mean they’ll be immune,” Galit Alter, one of the physician co-author and professor of medicine at Harvard Medical School, told the Journal.

“The good news is that most vaccines induce levels (of antibodies) much higher than these levels,” Alter said.

The need for multiple rounds of immunization suggests that more antigen or booster may be needed to push the immune system to generate functional immunity that may be needed for protection, the study noted.
