Filter by:Vaccination is a potentially critical component of efforts to arrest development and dissemination of antimicrobial resistance (AMR), though little is known about vaccination impact within low-income and middle-income countries. This study will evaluate the impact of vaccination on reducing carriage prevalence of resistant Streptococcus pneumoniae and extended spectrum beta-lactamase-producing Escherichia coli and Klebsiella species. We will leverage two large ongoing cluster-randomised vaccine evaluations in Malawi assessing; first, adding a booster dose to the 13-valent pneumococcal conjugate vaccine (PCV13) schedule, and second, introduction of the RTS,S/AS01 malaria vaccine. Six cross-sectional surveys will be implemented within primary healthcare centres (n=3000 users of outpatient facilities per survey) and their local communities (n=700 healthy children per survey): three surveys in Blantyre district (PCV13 component) and three surveys in Mangochi district (RTS,S/AS01 component). We will evaluate antibiotic prescription practices and AMR carriage in children ≤3 years. For the PCV13 component, surveys will be conducted 9, 18 and 33 months following a 3+0 to 2+1 schedule change. For the RTS,S/AS01 component, surveys will be conducted 32, 44 and 56 months post-RTS,S/AS01 introduction. Six health centres in each study component will be randomly selected for study inclusion. Between intervention arms, the primary outcome will be the difference in penicillin non-susceptibility prevalence among S. pneumoniae nasopharyngeal carriage isolates in healthy children. The study is powered to detect an absolute change of 13 percentage points (ie, 35% vs 22% penicillin non-susceptibility). This study has been approved by the Kamuzu University of Health Sciences (Ref: P01-21-3249), University College London (Ref: 18331/002) and University of Liverpool (Ref: 9908) Research Ethics Committees. Parental/caregiver verbal or written informed consent will be obtained prior to inclusion or recruitment in the health centre-based and community-based activities, respectively. Results will be disseminated via the Malawi Ministry of Health, WHO, peer-reviewed publications and conference presentations.
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
This is a prospective clinical study aiming to investigate on the transplacental antibody transmission post Covid-19 infection during pregnancy.
To evaluate the immunogenicity, lot-to-lot consistency and safety of three consecutive batches of Measles, Mumps and Rubella Combined Vaccine, Live.
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.
