Researchers claim they have found both human genes that make getting Covid-19 much less likely,
and identified 3 new already approved drugs that help resist getting infected

The research team also identified drugs that are currently on the market for different diseases that they claim block the entry of Covid-19 into human cells by increasing cellular cholesterol. In particular, they found three drugs currently on the market were more than 100-fold more effective in stopping viral entry in human lung cells:

Amlodipine, brand name Norvasc, by Pfizer, to treat high blood pressure and angina.

Tamoxifen, brand name Soltamox by Fortovia Therapeutics, an estrogen modulator, to treat breast cancer.

Ilomastat, brand name Galardin,
it’s a matrix metalloprotease inhibitor, that now being manufactured by many companies; a chemotherapy agent, with applications for skincare and anti-aging products.

The other five drugs that were tested — called PIK-111, Compound 19, SAR 405, Autophinib, ALLN -- are used in research but are not yet branded and used in clinical trials for existing diseases.

After intensive research the scientists and doctors claim they have found 30 genes that block the virus from infecting human cells including RAB7A, a gene that seems to regulate the ACE-2 receptor that the virus binds to and uses to enter the cell. The spike protein’s first contact with a human cell is through ACE-2 receptor.

I guess this means that some humans are born immune to Covid-19

This also may mean much less than 60% of a population will have to recover from a Covid-19 infection to reach “Herd Immunity”
