Dissecting humoral immune responses to an MVA-vectored MERS-CoV vaccine in humans using a systems serology approach. iScience 2024; 27:110470. [PMID: 39148710 PMCID: PMC11325358 DOI: 10.1016/j.isci.2024.110470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 06/11/2024] [Accepted: 07/03/2024] [Indexed: 08/17/2024] Open
Abstract
Besides neutralizing antibodies, which are considered an important measure for vaccine immunogenicity, Fc-mediated antibody functions can contribute to antibody-mediated protection. They are strongly influenced by structural antibody properties such as subclass and Fc glycan composition. We here applied a systems serology approach to dissect humoral immune responses induced by MVA-MERS-S, an MVA-vectored vaccine against the Middle East respiratory syndrome coronavirus (MERS-CoV). Building on preceding studies reporting the safety and immunogenicity of MVA-MERS-S, our study highlights the potential of a late boost, administered one year after prime, to enhance both neutralizing and Fc-mediated antibody functionality compared to the primary vaccination series. Distinct characteristics were observed for antibodies specific to the MERS-CoV spike protein S1 and S2 subunits, regarding subclass and glycan compositions as well as Fc functionality. These findings highlight the benefit of a late homologous booster vaccination with MVA-MERS-S and may be of interest for the design of future coronavirus vaccines.

Quantitative assay to analyze neutralization and inhibition of authentic Middle East respiratory syndrome coronavirus. Med Microbiol Immunol 2024; 213:6.

Abstract
To date, there is no licensed vaccine for Middle East respiratory syndrome coronavirus (MERS-CoV). Therefore, MERS-CoV is one of the diseases targeted by the Coalition for Epidemic Preparedness Innovations (CEPI) vaccine development programs and has been classified as a priority disease by the World Health Organization (WHO). An important measure of vaccine immunogenicity and antibody functionality is the detection of virus-neutralizing antibodies. We have developed and optimized a microneutralization assay (MNA) using authentic MERS-CoV and standardized automatic counting of virus foci. Compared to our standard virus neutralization assay, the MNA showed improved sensitivity when analyzing 30 human sera with good correlation of results (Spearman's correlation coefficient r = 0.8917, p value < 0.0001). It is important to use standardized materials, such as the WHO international standard (IS) for anti-MERS-CoV immunoglobulin G, to compare the results from clinical trials worldwide. Therefore, in addition to the neutralizing titers (NT50 = 1384, NT80 = 384), we determined the IC50 and IC80 of WHO IS in our MNA to be 0.67 IU/ml and 2.6 IU/ml, respectively. Overall, the established MNA is well suited to reliably quantify vaccine-induced neutralizing antibodies with high sensitivity.

Abstract
In response to the COVID-19 pandemic, multiple vaccines were developed using platforms such as viral vectors and mRNA technology. Here, we report humoral and cellular immunogenicity data from human phase 1 clinical trials investigating two recombinant Modified Vaccinia virus Ankara vaccine candidates, MVA-SARS-2-S and MVA-SARS-2-ST, encoding the native and the prefusion-stabilized SARS-CoV-2 spike protein, respectively. MVA-SARS-2-ST was more immunogenic than MVA-SARS-2-S, but both were less immunogenic compared to licensed mRNA- and ChAd-based vaccines in SARS-CoV-2 naïve individuals. In heterologous vaccination, previous MVA-SARS-2-S vaccination enhanced T cell functionality and MVA-SARS-2-ST boosted the frequency of T cells and S1-specific IgG levels when used as a third vaccination. While the vaccine candidate containing the prefusion-stabilized spike elicited predominantly S1-specific responses, immunity to the candidate with the native spike was skewed towards S2-specific responses. These data demonstrate how the spike antigen conformation, using the same viral vector, directly affects vaccine immunogenicity in humans.

Modified vaccinia virus Ankara (MVA) is used as a vaccine against monkeypox virus and as a viral vaccine vector. MVA-MERS-S is a vaccine candidate against Middle East respiratory syndrome (MERS)-associated coronavirus. Here, we report that cross-reactive monkeypox virus neutralizing antibodies were detectable in only a single study participant after the first dose of MVA-MERS-S vaccine, in 3 of 10 after the second dose, and in 10 of 10 after the third dose.

Abstract
Background The Middle East respiratory syndrome coronavirus (MERS-CoV) is a pathogen associated with an acute respiratory infection that has a high mortality rate in humans. It was first identified in June of 2012 in the Arabian Peninsula. The success of the COVID-19 vaccines has shown that it is possible to take advantage of medical and scientific advances to produce safe and effective vaccines for coronaviruses. This study aimed to examine the safety and immunogenicity of MERS-CoV vaccines. Methods The research method Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used as the guideline for this study. RevMan 5.4 software was used to perform a meta-analysis of the included studies. The safety was assessed by recording adverse events following vaccination, and the immunogenicity was assessed by using seroconversion. Results The study included five randomized controlled trials that met the inclusion criteria after screening. The studies had 173 participants and were performed in four countries. The vaccines examined were the ChAdOx1 MERS vaccine, MVA-MERS-S vaccine, and GLS-5300 DNA MERS-CoV vaccine. The meta-analysis showed no significant differences in local adverse effects (all local adverse effects and pain) or systemic adverse effects (all systemic adverse effects, fatigue, and headache) among participants in groups receiving a high-dose vaccine or a low-dose vaccine. There were, however, higher levels of seroconversion in high-dose groups than in low-dose groups (OR 0.16 [CI 0.06, 0.42, p = 0.0002]). Conclusion The findings showed that high doses of current MERS-CoV vaccine candidates conferred better immunogenicity than low doses and that there were no differences in the safety of the vaccines.

Abstract
Introduction Tick-borne encephalitis virus (TBEV) is an important human pathogen that can cause a serious disease involving the central nervous system (tick-borne encephalitis, TBE). Although approved inactivated vaccines are available, the number of TBE cases is rising, and breakthrough infections in fully vaccinated subjects have been reported in recent years. Methods In the present study, we generated and characterized a recombinant Modified Vaccinia virus Ankara (MVA) for the delivery of the pre-membrane (prM) and envelope (E) proteins of TBEV (MVA-prME). Results MVA-prME was tested in mice in comparison with a licensed vaccine FSME-IMMUN® and proved to be highly immunogenic and afforded full protection against challenge infection with TBEV. Discussion Our data indicate that MVA-prME holds promise as an improved next-generation vaccine for the prevention of TBE.
