Publication Abstract from PubMedTransmission-blocking vaccines have the potential to be key contributors to malaria elimination. Such vaccines elicit antibodies that inhibit parasites during their development in Anopheles mosquitoes, thus breaking the cycle of transmission.

Here, we present molecular analyses of human antibody responses generated in a clinical trial evaluating Pfs25 vaccination.
