Perspectives for subunit vaccines for the control of ticks

For the first time, successful vaccination against a tick has been carried out using a single defined antigen. Further, it has been shown that it is feasible to produce active antigenic material by recombinant DNA technology. This represents a significant advance towards the development of an alternative means of tick control. Nevertheless, as with any new product and new technology, much developmental work still has to be done before one can be confident that a practical means of tick control will result. From the published information, it does not seem that research on vaccines against other tick species is as advanced as that on Boophilus microplus. The work on B. microplus may, however, provide a short cut to the development of further tick vaccines.
