The most successful experimental vaccine to date is made with live attenuated infective larvae [1,2,3]. However, these vaccines are not suitable for widespread use in humans, and therefore other types of vaccines are being studied.

Staff at the Allen Parasite Immunology Lab are developing a DNA vaccine against filariasis.
