The RH blood type was discovered in 1940 during experiments on animals.
RH means Rhesus Factor.
Most people are RH+ (they have Rhesus in them).
In 1960, the polio vaccine was developed using monkeys, and it was found to be contaminated with Simian Monkey Virus (SV40) related to the Rhesus monkey.
SV40 is "thought to cause" tumors/cancer.
A lot of people received that vaccine, a percentage of which seems to match with RH+ blood type percentages.
They keep a database of "rare humans" with "golden blood" like RH-.
This is all related to the rhesus macaque monkey. Herpes B virus also comes from this monkey.
There was a movie called 12 Monkeys about this.
In a future world devastated by disease, a convict is sent back in time to gather information about the man-made virus that wiped out most of the human population on the planet.
