A Phase IIb randomised, participant-blinded, placebo-controlled, multi-centre phase IIb efficacy study in 2030 volunteers aged 65 and over. The study will assess the safety and efficacy of the co-administration of a viral vectored vaccine, MVA- NP+M1, and the annual recommended licensed inactivated influenza vaccine (IIV). Within the main cohort 100 participants will be recruited to an immunology sub-cohort.
The clinical study will evaluate safety and the immune response of a prime- boost regimen with a live attenuated influenza vaccine (LAIV) prime and an inactivated split influenza vaccine (IIV) boost with or without adjuvant.
This is a Phase 1/2, randomized, observer-blinded, active-controlled trial. Approximately 330 eligible subjects will be enrolled and randomized into 1 of 3 treatment groups as shown in the Trial Design table below. Each group will consist of approximately 110 subjects total, stratified by age, gender, and history of receipt of 2016 - 17 influenza vaccine. On Day 0, subjects in Groups A and B will be administered an IM injection of NanoFlu at one of two dose levels; subjects in Group C will receive the preconfigured comparator (Fluzone HD) at the manufacturer's recommended dose and volume. On Day 21, all Group A and B subjects will be administered a rescue injection with a licensed seasonal influenza vaccine, while all Group C subjects will be administered an injection with sterile saline placebo to maintain trial blind. Trial follow-up for each subject will span approximately 1 year from the Day 0.
This multi-site study assesses the impact of text message reminders on the receipt of the second dose of influenza vaccine, and takes place in practices from the American Academy of Pediatrics (AAP) Pediatric Research in Office Settings (PROS) network.
This randomized, modified double-blind, active-controlled, multi-center trial will assess the safety and immunogenicity of the high-dose quadrivalent influenza vaccine (QIV-HD) compared to either the licensed or investigational high-dose trivalent influenza vaccine (TIV-HD) in adults.
Influenza infection results in an estimated 31 million outpatient visits, 55,000 to 974,200 hospitalizations, and 3,000 to 49,000 deaths. Membership in household in which someone else has influenza is the major risk factor for contracting influenza. The household secondary attack rate (SAR) is as high as 19% based on laboratory-confirmed influenza and 30% based on symptoms. Non-pharmaceutical preventive measures, including education, may play a role in decreasing transmission, but are only effective if started within 36 hours of symptom onset in index cases. Yet, most interventions are delayed because they are not initiated until care is sought. The investigators have demonstrated in one primarily Latino, urban community sample, that text messaging can be used to rapidly identify community members with influenza-like illness (ILI) early in an illness. This early identification would enable implementation of an educational intervention in the optimal time frame to reduce influenza transmission. Providing education within a text message is a proven successful strategy to influence behavior. Text messaging itself is scalable, low-cost, and can be used in low literacy populations. However, using text-message based surveillance to trigger a real-time text-message behavioral educational intervention to decrease household influenza transmission has not been assessed.
The aim of this study is to characterize the immune profile of frail and healthy aged individuals and investigate their immune responsiveness including the response to influenza vaccine over an 18-month period. The project will include a longitudinal study to define immune signatures and multi-parameter profiles associated with frailty and may lead to the identification of predictive markers of evolution to frailty and Immunosenescence in the elderly.
The primary purpose of this study is to validate the sensitivity and specificity of the iTreat Flu A+B Test and the ellume.lab Flu A+B Test in detecting influenza A and influenza B as compared to viral culture. The secondary aims are to: Validate the sensitivity and specificity of the iTreat Flu A+B Test and the ellume.lab Flu A+B Test in detecting influenza A and influenza B as compared to Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). Evaluate the correct interpretation of the iTreat Flu A+B Test by subjects with influenza-like symptoms. Evaluate the subjects' satisfaction with the convenience, comfort and ease of use of the iTreat Flu A+B Test. Evaluate the operators' satisfaction with the ease of use of the ellume.lab Flu A+B Test.
The study consists of two arms (PHARM and PEER) designed to educate participants about three vaccine-preventable diseases (zoster, pneumonia, and influenza) and vaccination. PHARM will consist of a 60-minute presentation about the three vaccine-preventable diseases and their vaccinations delivered by a pharmacist, featuring a didactic lecture and discussion supplemented by video clips of community members discussing their experiences around vaccination, as well as physicians underscoring the importance of vaccination. PEER will consist of a 60-minute small-group session led by a peer educator which includes scripted roleplaying exercises designed to reinforce learnings pertaining to these three vaccine-preventable diseases and their vaccinations. The components of these interventions will be designed to address specific barriers to vaccination identified by literature search and our prior work in the area of community-based vaccine education. Both arms will focus primarily on pneumococcal disease and zoster but will include limited content on influenza because participants are likely to have questions about how the flu and its vaccination differ from pneumococcal diseases and zoster. The study will be implemented in an older, predominantly African-American (AA) population, consistent with our prior work in this area.
This phase I/II, randomized, modified double-blind, multi-center study will assess the safety and immunogenicity of a high-dose quadrivalent influenza vaccine (QIV-HD) in older adults (≥65 years).
