Zoonotic Parasite Nanovaccines: Progress, Challenges, and Future Perspectives.

Area of Science:

• * Parasitology and Vaccinology
• * Nanotechnology in Medicine

Background:

• * Parasitic infections are a significant global health concern, especially in low- and middle-income countries.
• * Traditional vaccines face limitations due to parasite complexity and immune evasion strategies.
• * Nanoparticle-based vaccines (e.g., mRNA-lipid, polymeric, virus-like particles) demonstrate enhanced immunogenicity.

Purpose of the Study:

• * To review recent advancements in nanoparticle-based vaccines for parasitic infections.
• * To detail the roles of different nanoparticle types in vaccine development.
• * To analyze challenges and provide future perspectives for parasite nanovaccines.

Main Methods:

• * Comprehensive literature review of nanoparticle-based vaccines for parasitic infections.
• * Analysis of various nanoparticle platforms (mRNA-lipid, polymeric, VLPs).
• * Examination of clinical, ethical, and regulatory challenges.

Main Results:

• * Nanoparticle vaccines, including mRNA-lipid particles, polymeric particles, and virus-like particles (VLPs), offer a promising alternative to traditional vaccines.
• * These nanovaccines exhibit improved immunogenicity in preclinical and clinical trials.
• * Significant challenges remain in the clinical translation and regulatory approval of parasite nanovaccines.

Conclusions:

• * Nanoparticle-based vaccines represent a significant advancement in combating parasitic infections.
• * Addressing clinical, ethical, and regulatory hurdles is crucial for successful implementation.
• * Further research is needed to develop next-generation parasite nanovaccines.
