Acknowledging the fallibilities of recalling events from more than three decades ago, the recollection of Richard Carter’s impact on the identification and development of Pfs25, a major surface protein of Plasmodium falciparum zygotes and ookinetes, and target of malaria transmission-blocking vaccines, remains unassailable. In fondest memories of Richard Carter’s many contributions, herein retells some memorable events along the tortuous journey toward the development of Pfs25 vaccines.
