Popis: | The protozoan pathogen Giardia lamblia is an important worldwide cause of diarrheal disease and malabsorption. Infection is managed with antimicrobials, although drug resistance and treatment failures are a clinical challenge. Prior infection provides significant protection, yet a human vaccine has not been realized. Individual antigens can elicit partial protection in experimental models, but protection is weaker than after prior infection. Here, we developed a multivalent nanovaccine by coating membranes derived from the parasite onto uniform and stable polymeric nanoparticles loaded with a mucosal adjuvant. Intranasal immunization with the nanovaccine induced adaptive immunity and effectively protected mice from G. lamblia infection. |
