NCT07310472
The goal of this intervention study is to learn if giving children influenza vaccinations in early childhood education facilities (i.e., daycare) will increase vaccination coverage compared to giving vaccinations only at healthcare. The main question it aims to answer is: • Does offering children nasal influenza vaccine in daycare result in higher proportion of children getting influenza vaccine. Researchers will compare daycare setting and healthcare setting as the location of giving influenza vaccines to children to see if more children will get vaccinated if they have an opportunity to receive nasal influenza vaccine at daycare. Participants in the intervention group will: • Have the opportunity to receive influenza vaccine in the daycare or in the healthcare Participants in the comparison group will: • Have the opportunity to receive influenza vaccine in the healthcare only
NCT06850051
The objective of this study is to evaluate the safety and immunogenicity of different vaccines of hemagglutinin formulations of trivalent influenza vaccine or of a combined respiratory syncytial virus / human metapneumovirus / parainfluenza virus type 3 vaccine in healthy participants 18 to 49 years of age. A lipid nanoparticle will be used in this study. Overall, the study is designed to: * Assess the safety profile of the candidate formulations * Describe the immunogenicity profile of the candidate formulations * Eligible participants will be randomized to receive a single intramuscular injection of either one of the vaccine formulations. Participants will be provided with a diary to solicit reporting of injection site reactions and systemic reactions, unsolicited Adverse Events (AEs), Serious Adverse Events (SAEs) and Adverse Events of Special Interest AESIs). Participants will also be required to record their daily temperature on the diary.
NCT07231016
Background: Both influenza and bone fractures are significant contributors to morbidity and mortality among older adults. This study evaluated the associations between influenza vaccination (IV) and adverse outcomes following fracture-related hospitalizations in elderly individuals. Methods: A retrospective cohort study was conducted utilizing data from a health insurance database in Taiwan. The study included 561,566 individuals aged 65 years and older who were hospitalized for fractures between 2009 and 2020. Patients were stratified according to whether they had received an IV within the 12 months preceding their fracture event. Propensity score matching was employed between the vaccinated and unvaccinated groups. Multivariate logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for postfracture infectious complications and 30-day mortality associated with prior IV.
NCT05836818
The goal of this research is to increase influenza vaccine acceptance and uptake in vulnerable populations whose primary (and often only) health care access occurs in emergency departments (ED Usual Source of Care Patients). Toward this goal, the investigators will conduct one on one interviews and focus groups with ED Usual Source of Care Patients and community partners and produce trusted messaging informational platforms (PROmotion of FLU VA(X)ccination in the Emergency Department - PROFLUVAXED) that will address barriers to flu vaccination, especially vaccine hesitancy. The investigators will then conduct a cluster-randomized, controlled trial of PROFLUVAXED platforms in six EDs to determine whether their implementation is associated with greater flu vaccine acceptance and uptake in ED Usual Source of Care Patients.
NCT03637036
To reach seasonal vaccination against influenza targets, University Hospitals Birmingham (UHB) already invites staff to take up the vaccination, and every November reminds staff that have not yet vaccinated to do so. The current protocol describes a randomized controlled trial (RCT) in which staff will be sent different reminders, and the investigators will compare the proportion of staff that go on to vaccinate after receiving each reminder.
NCT03307642
Children whose parents receive text reminders are more likely to be consented to participate in the school located influenza vaccination clinic than children whose parents do not receive text reminders.
NCT03137667
A cluster-randomized trial (clustering by school) was conducted in Monroe County, NY. Twenty middle and high schools were paired based on several characteristics and randomized within pairs to receiving a school-based influenza vaccination clinic or not (control).
NCT02227186
Children in schools in which influenza vaccination clinics are held during school hours will have higher rates of influenza vaccination than children in control schools (no school-located clinics offered)
NCT01046227
The patients of pediatric haemato-oncology have a higher risk for novel H1N1 influenza infection than general population, and they are strongly recommended to receive novel H1N1 vaccination. However, there is no previous data to answer how the efficacy and effectiveness of novel H1N1 vaccination is in patients of pediatric haemato-oncology. This study is designed to investigate the antibodies titers before and after the novel H1N1 influenza vaccination in these patients. Titer of H1N1 influenza virus antibodies will be determined by hemagglutinin inhibition assay (HAI). A HAI titer with a 4-fold rise or greater is defined as seroconversion. Study subjects with seroconversion are regarded as responsiveness to the vaccination. Meanwhile, if the patient presents influenza-like symptoms, we will perform throat swab or nasal swab for influenza rapid test, viral isolation, and novel H1N1 influenza PCR to confirm the diagnosis. After the study, we will be able to know whether or not current novel H1N1 influenza vaccination schedule is adequate and efficient for pediatric haemato-oncology patients.
