I mean the pharmaceutical companies spend billions of money every year trying to find a cure for diseases, illnesses ,virus,parasites,HIV and cancer so on.
How long will this take or where there be a cure?Have they not tried every drug combinations or how many drug combinations are there ?Like is it thousands , millions or billions?
Why no cure for lung cancer ,breast caner ,liver caner ,HIV or other cancers so on?
How are drugs made ?Do they use math to come up with drugs? Or try different combinations or use organism to kill diseases or illnesses ?
I really have no idea how the pharmaceutical companies work or go about looking for a cure or how conplex the problem is.
