Filter by:Previous studies have shown that a small incentive can have a large impact on health behaviors like vaccinating children. New Incentives, an international non-governmental organization (NGO), aims to boost demand for immunization by offering cash incentives to caregivers who have their child vaccinated at a program clinic. In collaboration with New Incentives, IDinsight is conducting a study to see whether this approach will increase immunization in North West Nigeria. This study aims to investigate whether giving cash to caregivers in North West Nigeria who bring their infants to receive vaccination against common infections (tuberculosis, diphtheria, tetanus, pertussis, hepatitis B virus (HBV) infection, Haemophilus influenzae Type B (Hib), pneumococcal bacteria, measles, rotavirus, polio, yellow fever) increases the proportion of children who are immunized. The study's main hypothesis is that New Incentives' program will increase the percentage of children immunized with BCG, any PENTA, or Measles 1 by an average increase of at least 7-percentage points across all program clinics that share a similar profile to the clinics New Incentives will operate in at scale. The study is taking place in Jigawa, Katsina, and Zamfara States between August 2017 and January 2020.
The study has two arms; both experimental and control areas will receive standard interventions given under polio eradication program of PCI. Participants in the experimental arm receive additional interventions on nutrition (improve diet diversity in pregnant women and children of 6-23 months) for exact 12 months. The study includes awareness generation (regarding nutrition) through community mobilization, counseling and capacity building of community mobilization.
The purpose of this study is to evaluate the immunogenicity and safety of different sequential immunization strategies by Sabin IPV and bOPV in Chinese infants.
This study aims to assess and confirm the adequate immunogenicity and safety profile of the Sanofi Pasteur's DTaP-Hep B-IPV-PRP-T fully liquid combined hexavalent vaccine administered in HIV-exposed uninfected infants and in HIV-exposed infected infants. The primary objectives of the study are: - To evaluate the immunogenicity of the study vaccine 1 month after the 3-dose primary series in HIV-exposed infected and in HIV-exposed uninfected infants. - To describe the persistence of all antibodies before receipt of the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. - To evaluate the immunogenicity of the study vaccine 1 month after the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. The secondary objectives of the study are: - To describe the safety profile after each and all doses of the study vaccine administered as a 3-dose infant primary series in HIV-exposed infected and in HIV-exposed uninfected infants. - To describe the safety profile of the study vaccine administered as a booster in HIV-exposed infected and in HIV-exposed uninfected infants.
The investigators propose to study both inter- and intra-household Oral Polio Vaccine (OPV) transmission in a primarily inactivated-polio vaccine (IPV)-vaccinated community in Mexico. The investigators will enroll 3 distinct clusters of households in a municipality in Orizaba, Veracruz, Mexico prior to the February 2015 National Immunization Week (NIW.) These clusters will be physically separate from one another and differ only in the proportion of OPV-eligible children who will receive OPV during the February 2015 NIW (10%, 30% and 70% vaccinated.) The investigators will look at inter-household and intra-household transmission. The investigators will then determine if epidemiologic (i.e.: degree of contact), anthropometric (i.e.: nutritional status) or clinical covariates (i.e.: IPV/OPV immunization history) are associated with intra-household transmission.
Phase II, observer-blind, randomized study on the safety, reactogenicity, immunogenicity and impact on intestinal shedding of a single dose of monovalent high-dose inactivated poliovirus type 2 vaccine (m-IPV2 HD) or a single dose of standard trivalent inactivated poliovirus vaccine (t-IPV) when given concomitantly with the third dose of bivalent oral poliovirus vaccine (b-OPV) to infants early in life
The aim of the study is to assess the immunogenicity of SP059 (IMOVAX POLIO®: Inactive Poliovirus Vaccine) vaccine against poliovirus and safety after fifth dose. Primary Objective: - To investigate the booster vaccine response rate against poliovirus types 1, 2 and 3 one month following the vaccination dose with SP059 as 2nd booster Secondary Objectives: - To investigate seroprotection rates (percentage of subjects presenting poliovirus neutralizing antibody titers above 1:8 (1/dil.) at pre- and post-booster time points, Geometric mean titers (GMT) at pre- and post-booster time points and geometric mean of individual titer ratio (GMTR). - To investigate the safety after dosing of SP059 as 2nd booster.
This study aims to assess if pictorial messages promoting routine immunization during supplementary campaigns for oral polio vaccine in areas with poor DTP3 vaccine coverage can improve immunization rates. A cluster randomized trial design in low literature populations will be used.
Globally, polio cases have decreased by over 99% since 1988. However, wild poliovirus cases continue in Pakistan. Conflict and lack of access to children due to on-going insecurity in tribal areas present special challenges in interrupting transmission rapidly. There exists limited knowledge on the effect of shorter intervals of mOPV vaccination on immunogenicity levels in young children. The aim of this study is to demonstrate the non-inferiority of shorter intervals (7 and 14 days) between doses of mOPV1 vaccine compared to the customary interval (30 days). A 4th arm will receive bivalent (bOPV) vaccine at standard intervals beginning at 6 weeks of age.
Hypothesis: The immunogenicity of oral polio vaccine (OPV) will be enhanced in Bangladeshi infants who receive bicarbonate buffer at the time of polio immunization.
