Roger Dodger knocks on wood:
So you haven't caught COVID yet. Does that mean you're a superdodger?
The race is on to figure out why: "Are these people just lucky or did they really have a mutation in their genes that was protecting them from infection?'"
"We've heard countless anecdotes about nurses and health-care workers, being exposed without any protection and remaining negative over and over again,"
Having a particular mutation in the HLA gene increases a person's chance of being asymptomatic by almost 10 times.
HLA signals to the immune system that cells are invaded and need help. That signal triggers a cascade of events that ultimately leads your body to make potent weapons specifically designed to fight SARS-CoV-2. These weapons include antibodies and T cells that uniquely recognize pieces of this virus. Once these targeted weapons are available, your immune system has a much easier time clearing up the infection.
The HLA gene increases a person's chance of being asymptomatic by almost 10 times.
Some people have T cells that are already pre-programmed to recognize and fight off SARS-CoV-2. So there's no delay in generating COVID-specfic weaponry. It's already there.
