• Circular RNA (circRNA) vaccines present a novel platform with advantages like stability and sustained antigen expression.

Purpose of the Study:

• To review recent advances in circular RNA (circRNA) vaccine development.
• To highlight the potential of circRNA vaccines against diverse pathogens, including antibiotic-resistant bacteria.
• To discuss challenges and future directions for circRNA vaccine technology.

Main Methods:

• Review of recent scientific literature on circRNA vaccine development.
• Analysis of synthetic circularization techniques and delivery approaches.
• Examination of immunological mechanisms induced by circRNA vaccines.

Main Results:

• circRNA vaccines demonstrate high stability, low innate immunogenicity, and sustained antigen expression.
• circRNA vaccines can induce protective immune responses against viral and bacterial pathogens.
• Evidence supports the application of circRNA vaccines against antibiotic-resistant bacteria.

Conclusions:

• circRNA vaccines are a versatile and emerging platform for next-generation vaccine innovation.
• This technology offers a viable alternative to conventional antimicrobial strategies.
• Further research is needed to address current challenges and optimize circRNA vaccine development.
