Special Issue Information
Dear Colleagues,
SARS-CoV-2, the causative agent of COVID-19, has emerged as a serious global pandemic. Vaccines have been developed as an effective public intervention for the COVID-19 epidemic, with multiple vaccines including mRNA, adenoviruses, and inactivated and recombinant vaccines. However, the transmissibility and immune escape of SARS-CoV-2 increased as different viral variants continued to emerge during transmissions, such as Delta and Omicron. In addition, reduction in vaccine effectiveness and even breakthrough infections have been widely reported, posing challenges to existing vaccines. Respiratory mucosal immunity plays a critical role in SARS-CoV-2 infection and transmission, triggering mucosal and systemic immune responses to neutralize viral particles. The induction of mucosal immunity by oral or intranasal vaccines has become one of the important directions for subsequent vaccine development. In addition, virus-specific T cell responses induced by betacoronavirus infection can generate broad-spectrum immune responses and long-lasting immune memory. Therefore, by exploring the common features of the betacoronavirus, designing peptide vaccines that contain conserved T cell epitopes and are effective against current and future potential variants has become a hotspot for next-generation vaccine development. An overview of the COVID-19 vaccines will help us broaden our horizons for future vaccine development. The goal of this study is to summarize the current understanding of various available SARS-CoV-2 vaccines, analyze crucial directions for the next-generation vaccine development by reviewing the current status and challenges of COVID-19 vaccines, exploring the impact on humoral and cellular immune activation and the duration of vaccine protection from multiple perspectives, including vaccine delivery and antigen format. This study belongs to the scope of vaccine technology.
In this Special Issue, original research articles and reviews are welcome. We look forward to receiving your contributions.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Vaccines is an international peer-reviewed open access monthly journal published by MDPI.
