Vaccination with intestinal tract antigens does not induce protective immunity in a permissive model of filariasis

- L. sigmodontis intestinal antigens (GutAg)exhibit qualities of hidden antigens.
- Infected mice develop allergy associated immune responses to GutAg.
- Vaccinated mice develop GutAg specific IgG1 and IgG2A antibodies.
- Mice vaccinated with GutAg are not protected from challenge infection.
