Abstract

The SARS-CoV-2 pandemic has highlighted the need for improved vaccines that can elicit long-lasting mucosal immunity. Although mucosal delivery of vaccines represents a plausible method to enhance mucosal immunity, recent studies utilizing intradermal vaccine delivery or incorporation of unique adjuvants suggest that mucosal immunity may be achieved by vaccination via non-mucosal routes. In this expert insight, we highlight emerging evidence from pre-clinical studies that warrant further mechanistic investigation to improve next-generation vaccines against mucosal pathogens, especially those with pandemic potential.

增强粘膜免疫的非粘膜疫苗接种策略
严重急性呼吸系统综合征冠状病毒2型疫情凸显了对能够引发长期粘膜免疫的改进疫苗的需求。尽管粘膜递送疫苗是增强粘膜免疫的一种可行方法,但最近利用皮内疫苗递送或掺入独特佐剂的研究表明,通过非粘膜途径接种疫苗可以实现粘膜免疫。在这一专家见解中,我们强调了临床前研究的新证据,这些证据需要进一步的机制研究,以改进针对粘膜病原体的下一代疫苗,特别是那些具有大流行潜力的疫苗。
