Transplant rejection was not understood until the 1950s.
Transplant "rejection" was not understood until after 1950.
Transplants between 1800 and 1950 were not very successful, this is because there was not things like tissue typing and immunosuppressive drugs available, these are important because tissue typing test that the tissue is compatible with the body it will be transplanted to, and immunosuppressive drugs destroy the immune system so that the antiboddies wont destroy the new organ.
If you're talking about organ transplants, it's because there were no anti-rejection drugs available on the market prior to this.
Joseph Murray performed the first successful transplant, a kidney transplant between identical twins, in 1954, successful because no immunosuppression was necessary in genetically identical twins.

Very few, since the success rate was poor.
They are relatively safe. (The NHS or your local health authority would not fund transplants if they were very unsafe - i.e had bad outcomes. Transplants are quite expensive, but most hospitals/health authorities consider the cost "worth it"- i.e they will fund the operation. This indicates that transplants are not 'high risk'- i.e risk does not outweigh the cost). Obviously, as with any medical procedure, there are some risks attached.
