Abstract: | For many parasites, the interaction between the immunogenicity of the parasite and the immunological response of the host is a dynamic equilibrium that allows both to survive, albeit often with severe consequences for the host. Vaccines, if intended as a means of parasite control, are unlikely to be generally successful if they do no more than mimic an immunological equilibrium that would be reached after natural exposure to the parasites. The situation must be tipped in favour of the host. It has been difficult to find ways around this impasse. One approach has been receiving practical attention over recent years, an approach that Peter Willadsen, Craig Eisemann and Ross Tellam have called vaccination against 'concealed' antigens. |
