摘要
Patients exhibit good tolerance to messenger ribonucleic acid(m RNA)vaccines,and the choice of encoded molecules is flexible and diverse.These vaccines can be engineered to express full-length antigens containing multiple epitopes without major histocompatibility complex(MHC)restriction,are relatively easy to control and can be rapidly mass produced.In 2021,the U.S.Food and Drug Administration(FDA)approved the first m RNA-based coronavirus disease 2019(COVID-19)vaccine produced by Pfizer and Bio NTech,which has generated enthusiasm for m RNA vaccine research and development.Based on the above characteristics and the development of m RNA vaccines,m RNA cancer vaccines have become a research hotspot and have undergone rapid development,especially in the last five years.This review analyzes the advances in m RNA cancer vaccines from various perspectives,including the selection and expression of antigens/targets,the application of vectors and adjuvants,different administration routes,and preclinical evaluation,to reflect the trends and challenges associated with these vaccines.
