To overcome the current pandemic, a vaccine will need to be developed. However, conventional vaccination via sub-cutaneous injection is expensive, time-consuming, and operationally complex; it will require many months or even years to complete, significantly prolonging the pandemic recovery process. This project aims to develop a robust, convenient, and easily administered delivery system for the eventual SARS-COV-2 vaccine, avoiding sub-cutaneous injection and the requirement for trained healthcare professionals in the vaccination process. This system will use thin polymer strips that dissolve rapidly (within several seconds) in the mouth and are loaded with viral antigens, providing an alternative vehicle that can easily and conveniently deliver a precise dose of vaccine to the sub-lingual mucosa. It has already been shown that sub-lingual vaccine delivery in liquid form is effective in producing an immune response to a variety of infectious agents. This project will advance these results to the thin-film platform, allowing vaccinations to be carried out in an operationally simple manner, and enabling the pace of global vaccination to dramatically increase.

为了克服目前的流行病，需要研制疫苗。然而，通过皮下注射的常规疫苗接种昂贵、耗时且操作复杂;它将需要数月甚至数年才能完成，从而显著延长了大流行的恢复过程。该项目旨在为最终的SARS-COV-2疫苗开发一种稳健、方便和易于管理的递送系统，避免皮下注射和在疫苗接种过程中对训练有素的医疗保健专业人员的要求。该系统将使用在口腔中快速溶解（在几秒钟内）并装载有病毒抗原的薄聚合物条，提供了一种替代载体，可以容易和方便地将精确剂量的疫苗递送到舌下粘膜。 已经表明，舌下递送液体形式的疫苗在产生对多种传染性病原体的免疫应答中是有效的。 该项目将把这些成果推进到薄膜平台，使疫苗接种能够以操作简单的方式进行，并使全球疫苗接种的速度大大加快。
