LEFT: Richard Carter at Stonehenge, Wiltshire, England in Summer 2018. Depicted in the background are his hand-drawn predicted structures of the major transmission blocking vaccine candidate antigens, Pfs230, Pfs48/45 and Pfs47.

RIGHT: Richard Carter’s predicted disulphide-bond structure for Pfs230, a major transmission blocking vaccine candidate antigen.

Inset: A reinterpretation of an early attempt of Richard Carter’s to discover fertilization ligands in Plasmodium falciparum. Represented are parts of the polymorphic region Pfs230 domain 4 and the polymorphic region of Pfs48/45 domain 2. Culleton and Carter, acrylic on pine, 2002.
