During the COVID-19 pandemic, mRNA (mRNA) vaccines emerged as leading vaccine candidates in a record time. Nonreplicating mRNA (NRM) and self-amplifying mRNA (SAM) technologies have been developed into high-performing and clinically viable vaccines against a range of infectious agents, notably SARS-CoV-2. mRNA vaccines demonstrate efficient delivery, long-lasting stability, and nonexistent risk of infection. The stability and translational efficiency of transcription (IVT)-mRNA can be further increased by modulating its structural elements. In this review, we present a comprehensive overview of the recent advances, key applications, and future challenges in the field of mRNA-based vaccinology.

Since its use during the COVID-19 pandemic, mRNA has emerged as a leading candidate vaccine platform for pandemic infections. A critical difference between RNA-encoded antigen and protein vaccines is that RNA-based vaccines require the antigen to be translated in the body, adding an important variable. Much of the research focus in the field has been on ways to increase expression, but inflammation plays a critical role.

Objective: The aim of this study was to assess the association between allergic reactions after COVID-19 vaccination and the history of high-risk allergy, individual predisposing factors such as age and gender, and COVID-19 vaccine type.
Materials And Methods: This retrospective cohort study included 234 adult patients (18 years old and above) who underwent a COVID-19 vaccine allergy test up until February 2023 in a Clinic of Allergy and Clinical Immunology in the University Clinical Center of Kosovo. All patients suspected of allergy underwent skin testing: SPT (skin prick test) and IDT (intradermal test) using either an mRNA (ribonucleic messenger acid) vaccine (BNT162b2, Pfizer-BioNTech) and/or an adenoviral vector vaccine (AZD1222, AstraZeneca).

The emergence of messenger ribonucleic acid (mRNA) vaccines as an alternative platform to traditional vaccines has been accompanied by advances in nanobiotechnology, which have improved the stability and delivery of these vaccines through novel nanoparticles (NPs). Specifically, the development of NPs for mRNA delivery has facilitated the loading, protection and release of mRNA in the biological microenvironment, leading to the stimulation of mRNA translation for effective intervention strategies. Intriguingly, two mRNA vaccines, BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna), have been permitted for emergency usage authorization to prevent COVID-19 infection by USFDA.

Cancer vaccines represent a transformative shift in oncology, aiming to prevent malignancies or treat established cancers by training the immune system to recognize tumor-specific or tumor-associated antigens. This review explores the diverse platforms and mechanisms supporting cancer vaccines, ranging from prophylactic vaccines such as HPV and hepatitis B vaccines that have significantly reduced virus-related cancers to therapeutic vaccines like Sipuleucel-T and T-VEC that extend survival in prostate cancer and melanoma. Vaccine types are classified, and delivery platforms including mRNA, peptide, dendritic cell and viral vector-based approaches are examined alongside pivotal clinical trial outcomes.

Despite the development of messenger ribonucleic acid (mRNA) vaccines for the infectious novel coronavirus 2 (SARS-CoV-2), further research on test methods is required to ensure their quality as well as rapid and effective approval for release to the market. During the current national lot release testing, identity tests cannot be conducted on other products using primers, probes, and in-house reference materials provided by the manufacturer and specific to one vaccine, because their sequences do not match. When key reagents and reference materials are dependent on the manufacturer in this way, difficulties in national lot release approval-which serves as an additional step for the government to verify product quality-arise if the manufacturer does not provide them.
