Filter by:This study was conducted on the basis of "Safety Observation of Sabin Strain Inactivated Polio Vaccine (Vero Cell) on primary Immunization, Booster Immunization and Simultaneous Vaccination with Other Vaccines in Infants and Young Children(ID: PRO-sIPV-MA4001-JX). Blood samples were collected in about 200 qualified subjects 1-9 months after their last vaccination of sIPV. And immunogenicity of sIPV and other vaccines simultaneously administrated will be tested, the antibodies against enterovirus (including EV71、CA16、CA6 and CA10) will also be tested.
Introduction: Good quality OPV campaigns can interrupt and possibly prevent transmission of the polio virus. Health care worker performance and motivation are prerequisites for the success of such campaigns. Complete, transparent and timely payments are, in turn, prerequisites for the sustenance of health care worker motivation and thereby efforts. To date, most such health care workers have been paid in cash, with chronic payment issues that have negatively affected campaign quality and vaccination coverage. Cash-based payments are often plagued with multiple delays in funds disbursements, cash leakages, and a lack of accountability and financial transparency. These difficulties have prompted a transition to digitized payments that are perceived to be faster, more convenient, traceable, reliable, easier and more reasonable to set up. The roll-out phase of these digital payment interventions has not been quantitatively evaluated and the effect of digital payments on the motivation, satisfaction and performance of health workers is not known. Therefore, this study will compare digitized payment of polio vaccination campaign health care workers with cash-based payment with regards to health care worker motivation, satisfaction and performance. Findings from this study may inform the operationalization of digital financial systems, and the transition towards cross-campaign digital payments. Primary Objectives: 1. To compare the motivation, satisfaction and performance of vaccination health care workers in areas where they are paid using mobile money versus in cash, 2. To explore how gender norms and relations influence health workers' response to payment systems (mobile money versus cash payments) and how these affect the health workers' performance and motivation in polio vaccination campaigns and Secondary objectives: 1. To compare vaccination campaign quality in areas where health care workers are paid using mobile money versus in cash 2. To compare vaccination coverage in areas where campaign health care workers are paid using mobile money versus in cash. 3. To estimate the incremental cost of the intervention. Methods: This will be a mixed methods study including a cluster-randomized controlled implementation trial and a qualitative study. A total of 60 districts be randomized to implement either a digital payment system for polio campaign vaccinators during the polio campaign or the traditional cash-based payment system.
The objective of the projects is to Develop and implement a Package of interventions that will comprise of an augmented communication and counseling strategy coupled with private sector involvement and a combined Oral Polio Vaccine and Inject able Polio Vaccine approach during the Polio campaigns followed by the evaluation of this project for acceptability, feasibility and effectiveness of the intervention Package.
The rationale for this study (IPV 002ABMG) is to evaluate and compare three doses of IPV, two doses of IPV plus one bOPV, and one dose of IPV plus two doses of bOPV in order to provide evidence for better immunization policy making in regions of the world that must switch to use of IPV/bOPV schedules in the 2014-2015 time frame. The goal is to identify the best option optimizing humoral immune responses, intestinal immunity and thereby prevent community transmission as well as preventing VAPP. Specifically, the study seeks to show that both of the sequential regimens are equivalent (not-inferior) to the 3-dose IPV regimen in the seroconversion rates to both type 1 and type 3 poliovirus such that not more than 10% of subjects fall below the 95% confidence interval observed for the 3-dose IPV alone regimen and the geometric mean titers (GMTs) are no more than 2/3 logs less than those for the 3-dose IPV regimen. In addition, the study will evaluate by a novel method (poliovirus shedding index), the adequacy of IPV vaccines in inducing intestinal immunity, specifically by reducing the shedding of poliovirus type 2 after an OPV challenge. The hypotheses of the study are: - A 3-dose IPV/bOPV sequential schedule including 1 or 2 doses of bOPV is non-inferior in terms of types 1 and 3 seroconversion rates and GMTs to a 3-dose IPV schedule. - Two and possibly 1 IPV dose(s) provides significant seroconversion rates and GMTs to type 2 poliovirus and sufficient priming to induce a rapid immune response in the context of an oral challenge at 7 months of age. - Three, 2, and possibly 1 dose of IPV will induce intestinal immunity to poliovirus type 2 as measured by a combination of quantity of virus in stools and duration of shedding (shedding index). In addition to these 3 hypotheses, the study will explore the following hypothesis: • Co-administration of bOPV and rotavirus at 16 weeks of age (the second rotavirus dose) provides similar antirotavirus IgA seroconversion rates and GMCs compared to subjects receiving rotavirus vaccine together with IPV.
This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swedish population for diseases included in the National Immunization Program (NIP), and to affirm the population's protection against polio. To be able to recommend complementary immunizations to immigrated children, a sub study focusing on foreign born teenagers will also be done and compared to children of the same age born in Sweden.
