Pneumococcal Vaccination in Patients With Inflammatory Bowel Disease

ABSTRACT: Patients with inflammatory bowel disease (IBD) will be assessed for immunologic response to pneumococcal vaccination. Patients with IBD meet criteria as outlined by the Centers for Disease Control (CDC) for pneumococcal vaccination, yet the investigators have found that pneumococcal vaccination in this population is under-utilized. It is unknown whether or not IBD or IBD-related medications impact the immune response to this recommended vaccine. Three groups of 25 patients each will be recruited. The first group will consist of outpatients with IBD who are receiving infliximab (Remicade TM) while on concommitant immunosuppressive therapy (with either 6MP, azathioprine, or methotrexate). This group is intended to represent a common ‘heavily immunosuppressed’ patient group with IBD. The second group will consist of patients with IBD seen in our outpatient clinic who are not on any immune-suppressive medications. These patients meet CDC criteria for vaccination by virtue of having a chronic medical illness. The third group will consist of healthy age-matched (to the first group) controls. After obtaining informed consent, patients will be screened with baseline lab tests including testing for antibodies against pneumococcus. At the baseline visit, patients will also undergo a brief medical history, physical examination, and assessment of their IBD disease activity. Included patients will then undergo a one-time intramuscular vaccination with 23-valent polysaccharide pneumococcal vaccine (Pneumovax TM). One month later, subjects will return for a blood draw to assess for response to pneumococcal vaccination.

Comparable CD8 + T cell responses to SARS-CoV-2 vaccination in single-cell transcriptomics of recently allogeneic transplanted patients and healthy individuals

Project description:Despite extensive research on SARS-CoV-2 vaccination responses in healthy individuals, there is comparatively little known beyond antibody titers and T-cell responses in the vulnerable cohort of patients after allogeneic hematopoietic stem cell transplantation (ASCT). In this study, we assessed the serological response and performed longitudinal multimodal analyses including T cell functionality and single-cell RNA sequencing combined with TCR/BCR profiling in the context of BNT162b2 vaccination in ASCT patients. In addition, these data were compared to publicly available data sets of healthy vaccinees. Protective antibody titers were achieved in 40% of patients. We identified a distorted B and T cell distribution, a reduced TCR diversity, and increased levels of exhaustion marker expression as possible causes for the poorer vaccine response rates in ASCT patients. IGHV gene rearrangement after vaccination proved to be highly variable in ASCT patients. Changes in TCRα and TCRβ gene rearrangement after vaccination differed from patterns observed in healthy vaccinees as well as unvaccinated ASCT patients and associated transplant donors. Crucially, ASCT patients elicited comparable proportions of SARS-CoV-2 vaccine-induced (VI) CD8+ T cells, characterized by a distinct gene expression pattern that is associated with SARS-CoV-2 specificity in healthy individuals. Our study underlines the impaired immune system and thus the lower vaccine response rates in ASCT patients. However, since protective vaccine responses and VI-CD8+ T cells can be induced in part of ASCT patients, our data advocate early post-transplant vaccination due to the high risk of infection in this vulnerable group.

Long-Term Programming of Antigen-Specific Immunity from Gene Expression Signatures in the PBMC of Rhesus Macaques Immunized with an SIV DNA Vaccine

Project description:The primary objective of this study was to evaluate response to a SIV DNA-based vaccine that was adminstered via vivo electroporation (EP) in rhesus macaques to further understand the molecular correlates of protection against SIV. In this study, rhesus macaques were immunized with a DNA vaccine including individual plasmids encoding SIV gag, env, and pol alone, or in combination with a molecular adjuvant, plasmid DNA expressing the chemokine ligand 5 (RANTES), followed by EP. At eight month post-vaccination, animals were challenged with SIV. Standard immunological assays, flow-based activation analysis without ex vivo restimulation and high-throughput gene expression analysis were performed to determine the host response to each vaccine regimen. The overall study was designed to evaluate the response to a SIV-DNA vaccination administered to animals via intramuscular electroporation. Chinese rhesus macaques were divided into three treatment groups (n=6 animals per group): Control (no vaccination), DNA vaccine alone (pCSIVgag, pCSIVpol, pCSIVenv), DNA vaccine with RANTES adjuvant (pCSIVgag, pCSIVpol, pCSIVenv, pmacRANTES). Eight months following the last vaccination, animals were infected with 25 MID of SIVmac251 and response to infection was monitored. RNA for microarray analysis was isolated from fresh PBMCs that were isolated from individual animals and treated overnight with a pool of overlapping SIV pol peptides or mock treated. Samples for microarray analysis were taken longitudinally at 8 months post-vaccination (pre-SIV challenge; biological n=5-6 per group for each treatment; technical n=2 for each sample) and at day 10 post-SIV challenge (n=5-6 per group for each treatment; technical n=2 for each sample).

Immune transcriptome in adult-onset Still’s disease with mild flare following administration of mRNA vaccine BNT162b2

Project description:Adult-onset Still’s disease (AOSD) patients represent a population for which vaccination can induce disease flare1. The COVID-19 pandemic vaccination programs presented these patients and their health care providers with a critical decision. Previously it has been described that AOSD patients can experience disease flare with COVID-19 vaccination but no one has yet reported their immune transcriptional and antibody response. Here we present the transcriptional response and anti-spike antibody profile of a 58-year-old male after vaccination with BNT162b2 who experienced a mild AOSD flare following the second vaccine.

Gene expression analysis of Influenza vaccine response in Young and Old - Year 1

Project description:We profiled gene expression from a stratified cohort of subjects to define influenza vaccine response in Young and Old Differential gene expression by human PBMCs from Healthy Adults receiving Influenza Vaccination (Fluvirin, Novartis). Healthy adults (older >65, younger 21-30 years) were recruited at seasonal Influenza Vaccination clinics organized by Yale University Health Services during October to December of 2010 M-bM-^@M-^S 2011 and 2011-2012 seasons. With informed consent, healthy individuals were recruited as per a protocol approved by Human Investigations Committee of the Yale University School of Medicine. Each subject was evaluated by a screening questionnaire determining self-reported demographic information, height, weight, medications and comorbid conditions. Participants with acute illness two weeks prior to vaccination were excluded from study. Blood samples were collected into BD Vacutainer Sodium Heparin tube at four different time points, once prior to administration of vaccine and three time points after vaccination on days 2/4, 7 and 28. Peripheral Blood Mononuclear Cells (PBMC) were isolated from heparinized blood using Histopaque 1077 in gradient centrifugation. About 1.0x10^7 freshly isolated PBMC were lysed in Triso and immediately stored in -800C. Total RNA in aqueous phase of Trisol - Chloroform was isolated in an automated QiaCube instrument using miRNeasy according to manufacturerM-bM-^@M-^Ys instructions. Integrity of RNA samples were assessed by Agilent 2100 BioAnalyser Samples were processed for cRNA generation using Illumina TotalPrep cRNA Amplification Kit and subsequently hybridized to Human HT12-V4.0 BeadChip at Yale Center for Genomic Analysis (YGCA).

Gene expression profiling after vaccination with the RTS,S candidate malaria vaccine in a controlled human malaria infection study

Project description:RTS,S is the sole candidate vaccine shown to provide protection against infection to malaria-naive adults challenged with mosquito-borne homologous falciparum malaria and protection against infection and clinical and severe disease to volunteers in malaria-endemic Africa who were exposed to diverse Plasmodium falciparum strains. In this experiment we profiled gene expression in PBMCs after vaccination with the RTS,S candidate malaria vaccine in a controlled human malaria infection study. Subjects were vaccinated with three doses of the RTS,S candidate malaria vaccine. Blood samples for PBMC isolation and subsequent gene expression analysis were taken on day 0 (0m), day of the third vaccination (8w), 1 day post third vaccination (8w1d), 3 days post third vaccination (8w3d), the day of the infection (10w), 1 day post infection (10w1d), and 5 days post infection (10w5d). After infection the subjects were closely monitored for parasitemia. The response to the controlled infection was recorded as follows: no parasitemia (P, protected), parasitemia in the same time frame as the control group (NP, not protected), parasitemia later than the control group (DL, delayed). In addition to the experimental factors, a confounding factor was identified in the data analysis related to the use of a specific kit batch (Kit A or B).

RNAseq of skin vaccination array

Project description:The study aims to determine the molecular signature associated with varying applications of a novel skin vaccination array, compared to traditional needle and syringe immunization. The hypothesis is that the vaccination array induces a better immune response compared to the needle and syringe and this is due to a heightened inflammatory profile at the site of vaccination. We performed the study on wild-type mice that received varying forms of immunization, including intradermal needle and syringe with or without vaccine, Nanopatch with or without vaccine, Nanopatch with vaccine with QS-21 adjuvant, and Nanopatch with vaccine at higher application energy.

mRNA COVID-19 vaccine elicits potent adaptive immune response without the acute inflammation of SARS-CoV-2 infection [CV8]

Project description:SARS-CoV-2 infection and vaccination elicit potent immune responses. Our study presents a comprehensive multimodal single-cell dataset of peripheral blood of patients with acute COVID-19 and of healthy volunteers before and after receiving the SARS-CoV-2 mRNA vaccine and booster. We compared host immune responses to the virus and vaccine using transcriptional profiling, coupled with B/T cell receptor repertoire reconstruction. COVID-19 patients displayed an enhanced interferon signature and cytotoxic gene upregulation, absent in vaccine recipients. These findings were validated in an independent dataset. Analysis of B and T cell repertoires revealed that, while the majority of clonal lymphocytes in COVID-19 patients were effector cells, clonal expansion was more evident among circulating memory cells in vaccine recipients. Furthermore, while clonal αβ T cell responses were observed in both COVID-19 patients and vaccine recipients, dramatic expansion of clonal gdT cells was found only in infected individuals. Our dataset enables comparative analyses of immune responses to infection versus vaccination, including clonal B and T cell responses. Taken together, our comparative analysis shows that vaccination induces a robust adaptive immune response, including a durable clonal B and T cell response, without the severe inflammation associated with infection.
