This could be good news for some.
HLA-DRB1*04:01 gene variant is found three times more often in asymptomatic carriers of SARS-CoV-2 than in patients with symptoms of COVID-19.
In other words these people seem to have really good immunity to the SARS-CoV-2 virus. They can still spread it though, even if they don’t get symptoms.
Unfortunately this same gene variant is associated with getting MS, so some on here may have this variant. But if your are unfortunate enough to have it, at least it seems to come with a silver-lining as far as Covid is concerned.
There is another as well which seems to help against Covid, HLA-B*15:01, If you have both then you’re very well protected.
