No, because what would happen is the cancer companies would charge like $100,000 for that shot. That would in turn bankrupt thousands of uninsured citizens who need the medicine to stay alive and support their families. But then when they go bankrupt, their wives will divorce them, and they will just end up killing themselves anyway. So in the end you've got a dead person anyway, and a broken family which will produce thousands of fucked up children who will end up growing up and becoming sociopaths, further reducing the quality of life for the rest of the population of the earth.
Duh.
