Abstract Background Sexual stage surface antigens are potential targets of transmission-blocking vaccines (TBVs). The gametocyte and gamete surface antigen P230, a leading TBV candidate, is critical for red blood cell binding during exflagellation and subsequent oocyst development. Here, the genetic diversity of Pvs230 was studied in Plasmodium vivax parasite isolates from the China–Myanmar border (CMB) and central Myanmar. Methods Plasmodium vivax isolates were collected in clinics from malaria-endemic areas of the CMB (143 samples) and...
