Of the tools that are available or envisioned, only a highly efficacious, long-lasting vaccine would provide the degree and duration of transmission-blocking needed to achieve the simultaneous protection applied across a whole population at contiguous risk that is required to reduce and maintain R0 < 1 for that entire area

But:

… taking Bill and Melinda Gates’ challenge to heart and considering it seriously, we have come to the conclusion that eradication just might be possible, but only if a new set of tools are developed that focus on reducing the effectiveness of the mosquito vector. … Could a vaccine alone eradicate malaria? … A vaccine used in combination with antimalaria drugs and vector control could be quite effective in reducing the disease burden. However, eradication is a different story. We would argue that, in addition to vaccines, antimalarial drugs, and presently available vector control methods, eradication will require special tools that we have yet to develop.
