The characterisation of human melanomas as immunogenic and the observa
tion of spontaneous regression have led to the development of active s
pecific immunotherapy in the form of vaccines for treatment of maligna
nt melanoma. These vaccines have recently been the subject of consider
able interest, particularly since the introduction of melanoma antigen
cloning, the identification of specific peptide sequences recognised
by the immune system, and better understanding of antigen presentation
. Today, melanoma vaccines are a significant therapeutic agent in trea
tment of malignant melanoma. There are many melanoma vaccines that are
in clinical trials which have produced very encouraging clinical resp
onses. This review discusses the different forms of melanoma vaccines
used in the 1990s and their current status in clinical trials.
