Filter by:The primary objective of the study is to determine the impact of a behavior change intervention that partners Orthodox priests with members of the Health Development Army (HDA) and train them to conduct newborn health outreach to increase rates of early initiation of and exclusive breastfeeding through 6 months and vaccination coverage at six months. Secondary objectives include: - Determine the impact of the intervention on infant growth at six months, observed and self-reported changes in nutrition and feeding practices of mother and infants, and early identification of newborn illness. - Design a culturally relevant, scalable intervention for community-based newborn and infant health in Gondar in partnership with local partners, the Federal Ministry of Health, and the Gondar Regional Health Bureau.
Pregnant women who get influenza are more likely than non-pregnant women to have serious complications, including hospitalizations, death, preterm labor and premature birth. Pertussis can cause hospitalization or death for newborns. However, influenza and Tdap vaccination rates for pregnant women are low nationally. In this study, the investigators will perform a randomized controlled trial aimed at practice change in obstetricians' offices, with an overall goal of reducing morbidity and mortality from influenza and pertussis infections.
A multicentre study to evaluate the impact of timing of whooping cough (pertussis) vaccination in pregnancy, with participants randomised to receive whooping cough vaccination at one of three time points in pregnancy.
This study will be conducted in four low-income areas of Bin Qasim Town Karachi. This will be a community based randomized control trial of 21 months duration. The trial will include four arms; arm A and B will enroll children age 14-18 weeks and randomize them to either full dose IPV (0.5ml) or fractional IPV (0.1ml). Arms C and D will enroll children at 9 months of age and randomize them to either fractional or full dose IPV. Children aged 14 weeks for arms A and B and 9 months for arms C and D living in the selected communities of Bin qasim Town Karachi who have not received IPV vaccine during routine immunization for arms A and B and who have documentary evidence of receiving IPV vaccine at 14 weeks of age for arms C and D will be eligible for enrollment. The investigators will exclude children who are found acutely ill or those requiring emergent medical care/hospitalization at the time of enrollment. The investigators will use the Demographic Surveillance System (DSS) in the four study areas to identify the households with eligible children. The children of the parents who agree to participate in the study will be screened for eligibility by the trained research associates. After randomization into four different arms, the study trained research vaccinators will administer the IPV or fIPV as per randomization. Children will be observed in the center for 30 minutes after vaccination before leaving for home. Parents/guardians of all the participants will also be requested to immediately report any adverse effect occurring later. This study will be conducted in compliance with this protocol, GCP guidelines and all applicable international and local regulatory requirements. The study has approval by the Ethical Review Committee of the Aga Khan University (AKU), the National Bioethics Committee of Pakistan, and ethical approval at WHO/Headquarters in Geneva. All study procedures will be conducted in AKU's field research sites from where subjects will be recruited. The Clinical Trials Unit (CTU) of AKU will be engaged in providing support for specific study procedures conducted at CTU such as randomization, management of vaccines (storage, dispensing and incineration), and other responsibilities agreed in writing. Adverse events following vaccine administration will be monitored and all serius adverse events will be reported within 24 hours to WHO, DSMB and AKU IRB. All the vaccines used are licensed in Pakistan and in routine use.
