Encapsulation of chimeric protein rSAG1/2 into poly(lactide-co-glycolide) microparticles induces long-term protective immunity against Toxoplasma gondii in mice

- PLG-rSAG1/2 microparticles sustained the rSAG1/2 release from microparticles.
- Released rSAG1/2 from microparticles retained the original antigenicity.
- PLG-rSAG1/2 microparticles induced long-term protective immunity against Toxoplasma gondii.
