Filter by:The goal of this interventional clinical trial is to investigate the impact of medicine and pharmacy-led education on patient acceptance rates of Prevnar 20 pneumonia vaccination in patients eligible to receive the vaccine. The education intervention and subsequent option to get the vaccine will be done while the patient is admitted to inpatient care, prior to discharge. The main questions the study aims to answer are: - Will supplemental education about the Prevnar 20 Pneumococcal vaccine influence patient acceptance rates when given a decision to receive it? - Is there any other statistically relevant qualitative reasoning behind the patient's final decision for accepting or refusing the vaccine?
The goal of this clinical trial is to find out which approach works better in getting more of the friends and connections of Latino adults get vaccinated against COVID-19. The main questions this study aims to answer are: 1. Can teaching people to use motivational interviewing help more friends and connections of Latino adults get the COVID-19 vaccine compared to just giving information about the vaccine? 2. What are the things that make it easier or harder for Latinos and networks to get the COVID-19 vaccine? 3. How does this intervention work in practice so that it can be made available to more people in the future The researchers will compare the vaccine rates of the friends and connections of Latinos who have been trained in motivational interviewing with those who have only been given information about the COVID-19 vaccine. This will help figure out which method works best to encourage more people to get vaccinated.
An Open Comprative Study of the Prophylactic Efficacy and a Non-comparative Study of the Immunogenicity and Safety of the Inactivated Whole-virion Concentrated Purified Coronavirus Vaccine (CoviVac), Produced by FSBSI "Chumakov Federal Scientific Center for Research and Development of Immune-and-Biological Products", on Volunteers at the Age of 18-60 Years
Vaccination is the best way to mitigate the coronavirus disease 2019 (COVID-19) pandemic, but the vaccine immunogenicity may be quite variable from person to person. There is increasing evidence suggesting that the gut microbiome is a major determinant of vaccine immunogenicity. Thus, the investigators investigated the relationship between gut microbiota and humoral immune response after COVID-19 vaccination.
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has caused pandemic since outbreak in 2020. Patients with HIV may be at higher risk than those without HIV for coronavirus disease 2019 (COVID-19). At present, limited data are available on the safety and immunogenicity of coronavirus vaccine for patients with HIV.
This is a prospective, single blinded randomized homologous/heterologous prime-boost vaccine clinical study, designed to assess the immunogenicity of heterologous prime-boost immunization with AZD1222 and MVC-COV1901 in adults. Participants will be healthy adults at the age of 20-70 years who have had their first dose of COVID-19 vaccine, AZD1222. All eligible participants of 2 prime-boost interval strata (28 to 42, 56 to 70 days) will be 1:1 randomly assigned to receive a single dose of either: - Homologous group: Intramuscular injection the same vaccine as their prime dose AZD1222 - Heterologous group: Medigen COVID-19 vaccine MVC-COV1901. The treatment phase of this study will be conducted in a single-blind fashion such that the subject will not know the identity of the subjects' study treatment assignment. After receiving the treatment, the participants will remain on study for 168 days following the boost vaccination. For the study primary objective, immunogenicity will be assessed during the duration of the study, including serologic neutralizing antibody titer against SARS-CoV-2, serological quantification of binding antibody to SARS-CoV-2 antigen, SARS-CoV-2 antigen specific B cell and T cell frequencies and cytokine levels. And Safety will be assessed during the duration of the study as follows: - Solicited adverse events (AEs; local and systemic) will be assessed for 7 days following each vaccination (Day 0 through Day 7 for the boost vaccination). - Unsolicited AEs will be recorded for 28 days following the boost vaccination. - Serious adverse events (SAEs) will be recorded from signing of the informed consent form through Day 168. - Adverse events of special interest (AESIs) will be recorded from the boost vaccination through Day 168. This study is going to be conducted in a single medical center in Taiwan. An appropriate number of participants will be screened to achieve approximately 44 evaluable participants for each group. Participants in each group will be divided into two subgroups according to the intervals, 28-42 days and 56-70 days, between the prime and booster doses.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused pandemic since outbreak in 2020. Patients with cancers may be at higher risk than those without cancer for coronavirus disease 2019 (COVID-19). At present, limited data are available on the safety and immunogenicity of COVID-19 vaccination for patients with cancer.
The coronavirus disease 2019 (COVID-19) caused by the infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)，resulting in more than 82 million confirmed cases and caused around 1.8 million deaths, as of 2 January 2021. The ongoing pandemic still poses unprecedented global threat to public health system worldwide. On December 31, 2020, the joint prevention and control agency of China Council announced that Sinopharm SARS-CoV-2 inactivated vaccine had been conditionally approved by National Medical Products Administration, and the protection rate was 79.34%. So far, more than 198 vaccines were currently in preclinical or clinical development. The investigators aimed to initiate an observational cohort of healthy individuals injected with SARS-CoV-2 Vaccine, which will perform a longitudinal, comprehensive analysis of the SARS-CoV-2 vaccine Induced adaptive immune responses.
Eligible,healthy infants who have finished the 3-dose-schedule of sIPV+DTaP combined vaccination clinical trial (NCT04054882) will be recruited and divided into 4 groups, and will receive vaccination at the age of 18-month-old as follows: Group 1: sIPV + DTaP + MMR, Group 2: sIPV only, Group 3: DTaP only, Group 4: MMR only. The immunogenicity and safety of the 4 groups will be compared and analyzed before and 30 days after vaccination.
The purpose of this study is to determine if adding dietary fiber, such as inulin, to a diet that does not have enough fiber would raise the levels of potentially beneficial bacteria, such as Bifidobacterium, in the gut. There is evidence to suggest that these microbes can affect gut health and immune response, including to vaccines. The investigators will examine how inulin in the diet (compared to the maltodextrin control) (1) causes changes in the composition and function of the gut microbes, (2) reduces gut inflammation and gut leakiness caused by the vaccine, (3) increases immune response to vaccination, and (4) changes the expression of important adhesion molecules on the surface of white blood cells. Intestinal and whole-body responses will be measured in all participants.
