Immune response to the yellow fever vaccine 17D.

ABSTRACT: Correlates of immune mediated protection to most viral and cancer vaccines are still unknown. This impedes the development of novel vaccines to incurable diseases such as HIV and cancer. In this study, we have used functional genomics and polychromatic flow cytometry to define the signature of the immune response to the yellow fever (YF) vaccine 17D (YF17D) in a cohort of forty volunteers followed for up to one year after vaccination. We show that immunization with YF17D leads to an integrated immune response that includes several effector arms of innate immunity including complement, the inflammasome and interferons, as well as adaptive immunity as shown by an early T cell response followed by a brisk and variable B cell response. Development of these responses is preceded, as demonstrated in three independent vaccination trials and in a novel in vitro system of primary immune responses (Modular IMmune In vitro Construct (MIMIC) system), by the coordinated up-regulation of transcripts for specific transcription factors including STAT1, IRF7 and ETS2 that are upstream of the different effector arms of the immune response. These results clearly show that the immune response to a strong vaccine is preceded by coordinated induction of masters transcription factors, that lead to the development of a broad, polyfunctional and persistent immune response that integrates all effector cells of the immune system.

Interferon and inflammasome networks are associated with lower neutralizing antibody responses to Yellow Fever vaccination

Project description:The immune response to vaccines is critically dependent on multiple host and environmental factors including acute and chronic infections as well as metabolic and/or pathophysiological states of the host. In this study, we used computational systems biology to analyze a cohort of Ugandan subjects following immunization with the Yellow Fever vaccine (YF-17D) to identify pre-vaccination molecular and cellular mechanisms that are associated with the response to the vaccine. By integrating gene expression profiling, cell subset phenotyping and cytokine measurements, we highlight the upregulated levels of interferon-regulated, and inflammasome genes and proteins at the time of vaccination as negative correlates of the antibody response to the YF-17D vaccine. We show that this innate immune response is associated with higher levels of genes that interact with bacterial components and with increased frequencies of Tr1 CD39+ IL-10 producing cells. Our results provide a framework to define the influence of environmental parameters present prior to vaccination on the response to vaccines in human populations

A systems immunology study comparing innate and adaptive immune responses in adults to COVID-19 mRNA (BNT162b2/mRNA-1273) and adenovirus vectored vaccines (ChAdOx1-S)

Project description:We longitudinally profiled plasma proteomes in 54 adults vaccinated with the BNT162b2 (Pfizer-BioNTech) or ChAdOx1-S (Oxford-AstraZeneca) vaccines. Blood was collected pre-vaccination (V0) and 1-7 days after the 1st doses (BNT162b2 or mRNA-1273, V1) to assess innate and early adaptive responses. We identified key differences in the immune responses induced by the ChAdOx1-S and BNT162b2 vaccines that were correlated with subsequent antigen-specific antibody and T cell responses or vaccine reactogenicity. We observed that vaccination with ChAdOx1-S but not BNT162b2 induced a memory-like response after the first dose, which was correlated with the expression of several proteins involved in complement and coagulation. The COVID-19 Vaccine Immune Responses Study (COVIRS) thus represents a major resource to understand the immunogenicity and reactogenicity of these COVID-19 vaccines.

Anti-SARS-CoV-2 antibodies elicited by COVID-19mRNA vaccine exhibits a unique glycosylation pattern

Project description:Messenger RNA-based vaccines against COVID-19 induce a robust anti-SARS-CoV-2 antibody response with potent viral neutralization activity. Antibody effector functions is determined by its constant region subclasses as well as by its glycosylation patterns, but their role in vaccine efficacy is not well understood. Moreover, whether vaccination induce antibodies with similar Fc structures and protection potential as in COVID-19 patients remains unclear. Here, we analyzed BNT162b2 vaccine-induced IgG subclass distribution and Fc glycosylation patterns, as well as their potential to drive effector function via Fc-gamma receptors and complement pathways. We identified a unique Fc composition of these antiviral protein antibodies that is distinct from COVID-19 patients and convalescences. Vaccine-induced anti-spike SARS-CoV-2 IgG displayed a pro-inflammatory Fc profile and superior Fab- and Fc-mediated function, as compared to antibodies generated during natural viral infection. Moreover, differences in the kinetics of IgG Fc structure formation and their engagement with immune receptors were observed between different age groups. These data highlight the heterogeneity of the IgG Fc response to SARS-CoV-2 infection and vaccination and suggest that they differently support long-lasting protection.

Transcriptional profiles in pregnant women in response to vaccination

Project description:Vaccination in pregnancy is an effective tool to protect both the mother and infant. Vaccines against tetanus, pertussis and influenza are recommended for use in pregnancy and new vaccines with specific indications for pregnancy are in the clinical trials pipeline. However our understanding of the immune response to vaccination in pregnancy is incomplete. We compared the effect of pregnancy on early (24 hours) transcriptional responses to vaccination. Pregnant mice and women were immunised with Boostrix-IPV, a vaccine containing pertussis antigens.

Proteomic and metabolomic signatures associated with the immune response in healthy individuals immunized with an inactivated SARS-CoV-2 vaccine

Project description:CoronaVac (Sinovac), an inactivated vaccine for SARS-CoV-2, has been widely used for immunization. However, analysis of the underlying molecular mechanisms driving CoronaVac-induced immunity is still limited. Here, we applied a systems biology approach to understand the mechanisms behind the adaptive immune response to CoronaVac in a cohort of 50 volunteers immunized with 2 doses of CoronaVac. Vaccination with CoronaVac led to an integrated immune response that included several effector arms of the adaptive immune system including specific IgM/IgG, humoral response and other immune response, as well as the innate immune system as shown by complement activation. Metabolites associated with immunity were also identified implicating the role of metabolites in the humoral response, complement activation and other immune response. Networks associated with the TCA cycle and amino acids metabolic pathways, such as phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, and glycine, serine and threonine metabolism were tightly coupled with immunity. Critically, we constructed a multifactorial response network (MRN) to analyze the underlying interactions and compared the signatures affected by CoronaVac immunization and SARS-CoV-2 infection to further identify immune signatures and related metabolic pathways altered by CoronaVac immunization. These results help us to understand the host response to vaccination of CoronaVac and highlight the utility of a systems biology approach in defining molecular correlates of protection to vaccination.

Blood transcriptome profiling reveals distinct gene networks induced by mRNA vaccination against COVID-19

Project description:Messenger RNA (mRNA) vaccines represent a new class of vaccines that has been shown to be highly effective during the COVID-19 pandemic and that holds great potential for other preventative and therapeutic applications. Understanding the underlying mechanisms of the immune responses induced by this novel vaccine type and their relation to vaccine responses might help to further refine and optimize future vaccine design. In this study, we conducted an in-depth analysis of the blood transcriptome before and 24h after second and third vaccination with licensed mRNA vaccines against COVID-19 in humans, following a prime vaccination with either mRNA or ChAdOx vaccines. Utilizing an unsupervised weighted gene correlation network analysis, we identified distinct gene networks of co-varying genes characterized by either an expressional up- or down-regulation in response to vaccination. Down-regulated networks were associated with cell metabolic processes and regulation of transcription factors, while up-regulated networks were associated with myeloid differentiation, antigen presentation, and antiviral, interferon-driven pathways. Within this interferon-associated network, we identified highly connected hub genes such as STAT2 and RIGI, potentially playing important regulatory roles in the vaccine-induced immune response. The expression profile of this network significantly correlated with S1-specific IgG levels at the follow-up visit in vaccinated individuals. Those findings could be corroborated in an independent cohort of mRNA vaccine recipients. Collectively, insights from this study might contribute to current research endeavors aimed at further enhancing/ or optimizing vaccine-induced immunity.

Vaccine-Elicited CD4 T Cells Induce Immunopathology Following Chronic LCMV Infection

Project description:CD4 T cells promote innate and adaptive immune responses, but how vaccine-elicited CD4 T cells contribute to immune protection remains unclear. Here we evaluated whether induction of virus-specific CD4 T cells by vaccination would protect mice against infection with chronic lymphocytic choriomeningitis virus (LCMV). Immunization with vaccines that selectively induced CD4 T cell responses resulted in catastrophic inflammation and mortality following challenge with a persistent form of LCMV. Immunopathology required antigen-specific CD4 T cells and was associated with a cytokine storm, generalized inflammation, and multi-organ system failure. Virus-specific CD8 T cells or antibodies abrogated the pathology. These data demonstrate that vaccine-elicited CD4 T cells in the absence of effective antiviral immune responses can trigger lethal immunopathology. Splenic GP66-specific CD4 T cells from mice immunized with either a LMwt vaccine (sham) or LMgp61 vaccine (CD4 vaccine) were purified by FACS on day 8 post-infection with LCMV clone 13

Single-cell multi-omics analysis revealing immune features of inactivated SARS-CoV-2 vaccination in systemic lupus erythematosus patients

Project description:The COVID-19 vaccine-induced immunity has been widely reported in the general population, but the protective immune response of COVID-19 vaccines in SLE patients (SLEs) remains largely unknown. Here, we performed a comprehensive and time-series investigation of immunological alterations induced by inactivated COVID-19 vaccines in SLEs and healthy controls using single-cell multi-omics methods. Compared with healthy controls (HCs), the lower titres of neutralizing antibodies and global transcriptomic and epigenomic changes in peripheral immune cells were detected in SLEs. Increased expression levels of inflammatory responses related genes and AP-1 family members were commonly detected in SLEs and HCs, along with increased activation of T cells and diversity of T cell receptor repertoire. However, this vaccine enhanced chromatin accessibility at interferon response factors (IRF) loci in monocytes and conventional dendritic cells (cDCs) from SLEs at the late stage after vaccination, which was confirmed by transcriptome data and distinct from HCs. Vaccine induced less differentiations of B cells, expanded clonotypes and class switching clonotypes in SLEs, which was associated with impaired neutralization antibodies. Our study provides a system biology assessment of the transcriptomic and epigenomic landscape during an immune response induced by COVID-19 vaccine within SLEs, providing insights that will be useful in the optimization of vaccination strategies in immune compromised populations.
