Previously, we developed a coronavirus disease 2019 (COVID-19) protein subunit vaccine ZF2001® based on the tandem homo-prototype receptor-binding domain (RBD)-dimer of the SARS-CoV-2 spike protein. We upgraded the antigen into a hetero-chimeric prototype (PT)-Beta or Delta-BA.1 RBD-dimer to broaden the cross-protection efficacy and prove its efficiency with protein subunit and mRNA vaccine platforms. Herein, we further explored the hetero-chimeric RBD-dimer mRNA vaccines and evaluated their broad-spectrum activities as booster jabs following two doses of inactivated vaccine (IV) in mice. Our data demonstrated that the chimeric vaccines significantly boosted neutralizing antibody levels and specific T-cell responses against the variants, and PT-Beta was superior to Delta-BA.1 RBD as a booster in mice, shedding light on the antigen design for the next-generation COVID-19 vaccines.</p></div>","PeriodicalId":36178,"journal":{"name":"Biosafety and Health","volume":"5 2","pages":"Pages 89-100"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9979697/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9425351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bangladesh, like many other developing countries, is experiencing frequent dengue outbreaks. This article, therefore, critically discussed the current status of dengue disease, vector control approaches, and the need for <em>Wolbachia</em>-mediated intervention in Bangladesh and other dengue-endemic developing countries. In this narrative review study, relevant literature was searched from major databases and search engines such as PubMed, BanglaJol, World Health Organization (WHO)/European Centre for Disease Prevention and Control (ECDC) and Google Scholar. Considering the selection criteria, our search strategies finally involved 55 related literature for further investigation. Findings showed that current vector control strategies could not render protection for an extended period, and the disease burden of arboviruses is increasing. The impoverished outbreak preparedness, urbanization, climate change, and less efficacy of existing control methods have made people susceptible to vector-borne diseases. Hence, <em>Wolbachia</em>, a naturally occurring endosymbiont of many mosquito species that can potentially limit virus transmission through several host genetic alterations, would be a potential alternative for dengue prevention. We also critically discussed the challenges and prospects of <em>Wolbachia</em>-based dengue control in developing countries. The evidence supporting the efficacy and safety of this intervention and its mechanism have also been elucidated. Empirical evidence suggests that this introgression method could be an eco-friendly and long-lasting dengue control method.

Viral genotypes were identified during 19 outbreaks, and HAstV-1 was predominant (8/19, 42.10%). Eleven outbreaks were caused by mixed infection, and norovirus (9/11, 81.82%) and rotavirus (5/11, 45.45%) were the most common mixed pathogens.

To minimize the risk of transmissible infections, the production of human albumin solutions includes rigorous donor selection and plasma testing, and effective pathogen removal and inactivation methods such as fractionation and pasteurization. Compliance with international pharmacopeial standards for purity and prekallikrein activator and aluminum content is crucial, as is post-marketing pharmacovigilance for the continuous monitoring of adverse events. This review focuses on the effectiveness of manufacturing methods in the production of plasma-derived albumin, to ensure the safety of hyperoncotic solutions for volume expansion. We evaluated evidence identified through online database (PubMed) searches and from unpublished sources, on the manufacturing and pathogen safety of plasma-derived albumin solutions. The results confirmed the already established and evolving pathogen reduction capacity of the reviewed manufacturing methods. Up-to-date post-marketing pharmacovigilance data and log₁₀ reduction factors for known and emerging pathogens during albumin production are included. Towards the goal of ever-increasing clinical safety, potential areas of improvement, such as compliance rates for the completion of donor health questionnaires, are also discussed.
