Filter by:Supported be a digital vaccine registry the investigators will test the impact of automated appointment reminders, real time appointment reminders, motivational interviewing and targeted vaccine on routine childhood vaccine completion rates.
This study will test the relative efficacy of high-risk messages in increasing flu shot rates in patients at moderately high risk for flu and complications (those in the top 11-20% of risk). It will also examine whether informing patients that their high-risk status was determined by analyzing their medical records or by an artificial intelligence (AI) / machine-learning (ML) algorithm analyzing their medical records will affect the likelihood of receiving a flu vaccine.
The purpose of this study is to investigate the correlation of intention to receive COVID-19 vaccine, recommendation behavior, and 5C psychological antecedents among Nurses. The results can be used to assist suggestions in the health education provided by nurses on the topic of COVID-19 pneumonia and its vaccination. The purpose of the study is also wants to build a basis for future research and public support in vaccine decision-making, as well as to enhance the promotion of vaccine policy and enhance the resilience of the whole population during the pandemic ear.
A two-phases study will be carried out with the following aims 1. st phase (2018-2020) - To investigate the vaccination coverage for Rotavirus vaccine (RV) in Campania Region together with other pediatric vaccinations scheduled in the first 12 months of life: hexavalent, pneumococcal conjugate (PCV), meningococcal B (MenB) - To collect data on appropriate timing of the 3 doses of human bovine pentavalent reassortant vaccine (RV5) administration - To evaluate the frequency of a co-administration of RV5 with other vaccines scheduled in the first 12 months of life (hexavalent/PCV+RV5, MenB+RV5 vs RV5 alone) and assess the variability in co-administration rates according to RV5 dose 2. nd phase (2020-2022) - To investigate the effect of Coronavirus-Disease-19 (COVID-19) pandemic on vaccination coverage in the first year of life, focusing on RV vaccination - To investigate the effect of COVID-19 pandemic on timing of vaccine administration in the first year of life, focusing on those vaccines without catch-up vaccination schedule (i.e. RV) Hypothesis are the following: - Vaccination coverage and timing of vaccines scheduled in the first year of life are not fully aligned with what is established by the Italian National Prevention Plan 2017-2019 - Co-administration of RV5 and MenB in comparison with other coadministration e.g. hexavalent/PCV is lower - Co-administration of RV5 and MenB allows to ensure appropriate timing of RV vaccination schedule - COVID-19 pandemic may have affected the overall vaccination coverage as well as the timing of selected vaccination scheduled in the first year of life, with a more relevant impact on vaccines for whom a catch-up vaccination schedule is not feasible, such as RV immunization.
Background: ISHLT and AASLD guidelines recommend SARS-CoV2 vaccination in all individuals undergoing lung and liver transplantation, but there are currently scarce data on the safety and efficacy of these vaccines in this population. In Italy, immunocompromised patients have received the indication to be administered mRNA vaccines only. Primary outcome: safety and reactogenicity Secondary outcomes: immunogenicity and prevention of COVID19 Visits and timepoints: - T0: before first dose administration: visit and venous sampling to assess baseline COVID19 serum status - Telephone calls to assess safety and reactogenicity 1 and 2 days after each dose of vaccination - T21 or 28 (based on vaccine; mRNA BNT162b2 and mRNA-1273, respectively): visit, venous sampling to assess immunogenicity - Follow up visits after 60, 120, 180 and 365 from T0: visit and venous sampling to assess immunogenicity
Aim of this study is to evaluate whether COVID-19 vaccination induces a persistent cellular immune response. To this aim, blood samples are taken from vaccinated individuals and not immunized subjects as a control group. Cells isolated from blood samples are tested in vitro to assess the percentage of spike-specific T and B lymphocytes 1 and 7 months after a second dose of Comirnaty vaccine.
This randomized controlled trial tested the effect of culturally tailored and standard electronic secure messages and mailings from patients' primary care physicians to encourage COVID-19 vaccination among adults aged 65 and older.
Background: Vaccines against SARS-CoV-2, the virus that causes COVID-19, have been highly effective against preventing severe disease. But the protective effects of these vaccines appear to wane over time. Researchers want to learn why. Objective: To learn more about how the immune system responds to vaccines against infections like SARS-CoV-2. Eligibility: Healthy adults ages 18 or older who are scheduled to receive either a new vaccine or a booster shot against SARS-COV-2 or another emerging infection. Design: Participants will be screened with a medical history and blood and urine tests. Participants will have up to 8 study visits in 1 year. Each visit should last less than 2 hours. At each visit, participants will give blood samples. Some blood samples will be used for genetic testing. They will also give updates on their health. After the first study visit, participants will receive either a first vaccination or a booster shot. They must get the vaccine in their community or workplace. They will not get the vaccine at NIH. This study currently focuses on SARS-CoV-2, but it will expand to other infectious diseases as they emerge and become the target of new vaccines. ...
Chronic kidney disease (CKD) including patients on dialysis and kidney transplant recipients. represents the special subgroups of patients that required protection during the Severe Coronavirus Disease 2019 (COVID-19) pandemic .Since COVID-19 is associated with severe morbidity and mortality in these particular subgroup of patients, the main strategies is proper and rapid vaccination. CKD patients usually have a reduced immune responses, vaccination in these group of patients usually require higher dosage and more frequent dose since the vaccine response is short-lived and less response especially in dialysis patients5 .In patients with normal renal function,the immunity is durable but with modest declines at 6-8months. One study showed a linear decline in IgG in dialysis patients for up to 3months , but there are otherwise limited data. Previous reports of the vaccination in CKD patient involved mainly the mRNA vaccines. The recent reports of seroconversion rate dialysis patients receiving two doses of BNT 162b2 vaccine (Pfizer BioNtech) was lower than in control. In Thailand, the main vaccines available are Coronavac (Sinovac Life Science, Beijing, China) and ChadOx1 nCoV-19 (Oxford-Astra Zeneca) which was dispensed all over the country since April 2021. Data of the efficacy and safety of these vaccines in these patient groups is lacking. Therefore, the aim of this study is to measure the antibody and cellular responses in CKD patients including those with dialysis therapy and kidney transplantation and monitor the adverse events after the first and second doses of after vaccination. The incidence rate of Sars-COV2 infection post vaccination was also observed.
The objective of this study is to better understand public attitudes towards coronavirus disease 2019 (COVID-19) vaccination. This understanding will inform the development of community engagement strategies to be used in future interventions and studies aimed at addressing factors that impact the disproportionate burden of COVID-19 in under-served and vulnerable communities.
