Generalized urticaria induced by the Na-ASP-2 hookworm vaccine: Implications for the development of vaccines against helminths
The Journal of Allergy and Clinical Immunology,
Diemert DJ et al. – Infection with N americanus induces increased levels of total and specific IgE to Na–ASP–2 that result in generalized urticaria on vaccination with recombinant Na–ASP–2. These data advance knowledge of vaccine development for helminths given their propensity to induce strong TH2 responses. Study data highlight the important differences between the immune responses to natural helminth infection and to vaccination with a recombinant helminth antigen.
