Abstract:
Messenger RNA (mRNA) vaccines are composed of mRNA sequences encoding pathogens. The first coronavirus mRNA vaccine (BNT162B2, Pfizer/BioNTech), approved in the United Kingdom in 2020, had prevented approximately 20 million deaths globally within the first year of use. mRNA vaccines were initially used against tumors and infectious diseases, but recent research has also turned its attention to the prevention of allergic diseases. Here, we summarized the characteristics and outcomes of mRNA vaccines in preventing allergic diseases and analyzed their advantages over traditional inactivated vaccines and DNA vaccines. This review focused on the feasibility, potential mechanisms, and preclinical research results of prophylactic allergen mRNA vaccines in the prevention of type I hypersensitivity reactions, and preliminarily addressed the key issues in clinical trials of allergen mRNA vaccines. Allergen mRNA vaccines hold promise for preventing IgE-mediated allergic diseases, yet their potential uses warrant further clinical investigations.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
