Background:

• Nanocarriers (NCs) are engineered nanosized delivery systems with unique properties like biocompatibility and targeted delivery.
• These characteristics make NCs ideal for vaccine development, improving antigen stability, retention, and immune responses.
• Nanovaccines offer potential solutions to limitations of conventional vaccines regarding efficacy and resource consumption.

Purpose of the Study:

• To review the types, advantages, and limitations of nanocarriers (NCs) in vaccine development.
• To provide updates on nanovaccine candidates in clinical trials for infectious diseases and cancer.
• To highlight key lessons learned and future research directions for nanovaccine advancement.

Main Methods:

• Literature review of nanocarrier technology and nanovaccine development.
• Analysis of nanovaccine candidates in clinical trials for infectious diseases and cancer.
• Discussion of challenges and opportunities in nanovaccine research and development.

Main Results:

• NCs enhance vaccine efficacy through improved antigen stability, targeted delivery, and adjuvant effects.
• Several nanovaccine candidates are progressing through clinical trials for infectious diseases and cancer.
• Challenges include understanding NC mechanisms, upscaling, safety, and regulatory hurdles.

Conclusions:

• Nanovaccines represent a promising frontier in vaccine technology, offering enhanced efficacy and personalized approaches.
