To ensure efficacy against wild poliovirus, Jonas Salk methodically classified circulating polio strains before choosing three to use in his inactivated vaccine.1 Several other successful vaccines against viruses and bacteria have likewise included immunogen variants that were selected through careful assessments of pathogen genetic diversity and strain-specific protective immunity. In contrast, virtually all vaccines against the malaria parasite Plasmodium falciparum, including RTS,S/AS01, have been designed with the use of genetic sequences that are derived from a single, well-characterized reference strain thought to be of West African origin — 3D7. In light of the extreme diversity of malaria parasites, could . . .
