Over the past several years, messenger RNA (mRNA) vaccine has evolved from a term familiar only to vaccine scientists into one easily recognized by much of the general population. This change occurred because of the remarkable success of effective and safe mRNA vaccines during the COVID-19 pandemic that saved countless lives. Although mRNA vaccine technology has a clear use for combating future emerging diseases, its role in fighting currently known pathogens, such as HIV-1, is not well defined. This review summarizes mRNA vaccine technology, highlighting its success during the COVID-19 pandemic. It then addresses past and current efforts to develop a vaccine for HIV-1, including how mRNA vaccine technology has created opportunities in the ongoing search for an effective HIV-1 vaccine.

Humans and predators occupy dominant positions in ecosystems and are generally believed to play a decisive role in maintaining ecosystem stability, particularly in the context of virus transmission. However, this may not always be the case. By establishing some ecosystem virus transmission models that cover both human perspectives and predators, we have drawn the following conclusions: (1) Controlling vaccination activities from the human perspective can potentially lower the transmission rate and improve herd immunity, thereby indirectly protecting unvaccinated risk groups.

Liquid biopsy is gaining importance in oncology in the age of precision medicine. Extracellular vesicles (EVs), among other tumor-derived indicators, are isolated and analysed from bodily fluids. EVs are secreted by both healthy and cancerous cells and are lipid bilayer-enclosed particles that are diverse in size and molecular makeup.

Purpose: Outer membrane vesicles (OMVs) derived from Gram-negative bacteria naturally serve as a heterologous nano-engineering platform, functioning as effective multi-use nanovesicles for diagnostics, vaccines, and treatments against pathogens. To apply refined OMVs for human theranostic applications, we developed naturally exposed receptor-binding domain (RBD) OMVs grafted with antigen 43 as a minimal modular system targeting angiotensin-converting enzyme 2 (ACE2).
Methods: We constructed -derived OMVs using the antigen 43 autotransporter system to display RBD referred to as viral mimetic Ag43β700_RBD OMVs.

Introduction: Animal influenza viruses pose a danger to the general public. Eurasian avian-like H1N1 (EA H1N1) viruses have recently infected humans in several different countries and are often found in pigs in China, indicating that they have the potential to cause a pandemic. Therefore, there is an urgent need to develop a potent vaccine against EA H1N1.

The drug resistance problem of needs to be solved urgently. Here, we report the rapid identification of human antibodies by high-throughput single-cell RNA and VDJ sequencing of memory B cells derived from 64 volunteers immunized with recombinant five-component vaccine (clinical phase I). From 676 antigen-binding IgG1 clonotypes, TOP10 sequences were selected for expression and characterization, with the most potent one, Abs-9, having nanomolar affinity for the pentameric form of the specific antigen protein A.
