Filter by:Rotavirus is the leading cause of severe gastroenteritis in infants and young children worldwide and is estimated to account for 600,000 deaths in children <5 years of age. However, live oral enteric vaccines (e.g. OPV, cholera vaccines, typhoid vaccine) have been less immunogenic in poor communities with high levels of malnutrition and poor sanitation. Rotavirus vaccines also appear to be less immunogenic in the setting where they are most needed. High maternal antibody (IgG) to rotavirus and breast feeding near the time of vaccination may inhibit rotavirus vaccine effectiveness. We propose a quick study to look at practical ways to improve the immunogenicity of rotavirus vaccine in our own setting in Bangladesh. The objectives are to assess if delaying Rotarix vaccination will improve the immune response to the vaccine and to assess if avoiding breastfeeding in the 45 minutes before and after vaccine administration will improve the immune response to administration of Rotarix vaccine. The study will be conducted in the urban Dhaka Mirpur Community, a setting where previous rotavirus vaccine immunogenicity studies have been successfully conducted. A total of 300 infant will be randomly assigned to one of the following groups: 1) Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus vaccine with no intervention in normal breastfeeding practices before and after receiving vaccine. 2) Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration. 3) Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus, with no intervention in normal breastfeeding practices before and after receiving vaccine. 4) Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration. Blood and stool samples will be collected from infants and breast milk from mothers. The primary outcome is to determine the sero-conversion rate of anti-rotavirus IgA in different groups of infants.
Effects on weight will be monitored in healthy infant subjects consuming assigned infant formulas.
This study is initiated to investigate the gastrointestinal tolerance of a new infant formula in healthy, term, Asian infants.
The proposed Japanese Encephalitis (JE)Vaccine study is a four-arm double-blind randomized controlled single center trial to evaluate, by examining post-vaccination seroprotection titers, the lot-to-lot consistency of three lots of JE live attenuated SA 14-14-2 vaccine manufactured in a new GMP facility, and to establish non-inferiority of the new vaccine in comparison to a single lot of the same vaccine manufactured in the existing facility. The study will enroll a total of 1,000 Bangladeshi infants aged 10 to 12 months. In addition to providing immunogenicity data, JEV05 will provide local safety data of JE live attenuated SA 14-14-2 vaccine among Bangladeshi children. This will be the first step to secure licensure for this life-saving vaccine in Bangladesh as well as provide data to support WHO prequalification of JE live attenuated SA 14-14-2 vaccine.
This randomized clinical trial will assess the immune response in infants following administration of three types of oral poliovirus vaccine trivalent OPV (tOPV), monovalent OPV type 1 (mOPV1), bivalent OPV types 1 and 3 (bOPV) using two different schedules: a short schedule with administration at two week intervals and the usual schedule at four week intervals. The results of this study will guide the Global Polio Eradication Program in the implementation of new strategies that may: 1) improve the quality of the response to outbreaks following importation of wild poliovirus type 1 by shortening the interval at which several OPV doses are provided; 2) prevent alternate outbreaks of type 1 and type 3 poliovirus by using bOPV in outbreak responses in countries with weak routine immunization systems; and 3) prevent the emergence of type 2 vaccine-derived poliovirus through the replacement of tOPV with bOPV in immunization campaigns and routine immunization programs.
This randomized trial has two sets of diapers-- a normal one and one that has tips for how to talk to and engage your toddler. The investigators are hoping that the intervention improves language development.
In this study the effect of Infant formula with added Inulin will be compared with the effect of Infant formula without Inulin on the Bifidobacterium level in stool. It is expected that drinking Infant formula with added Inulin will result in higher beneficial bacteria level in stool compared to an Infant formula without Inulin.
The frequency of iron deficiency anemia was extensively studied in infants on the first year of life. There is not enough information about the frequency of iron deficiency during the second and third years of life. In a previous study performed in Israel and published in Pediatrics 2006 the incidence of anemia does not decrease towards age 18 months. Then there is reasonable to study the iron deficiency frequency beyond this age.
There is a paucity of information on whether and how the composition of formulas fed to infants influences their short-term feeding behaviors during the first few months of life. The purpose of this study is to investigate whether the composition of infant formula affects infants' feeding behaviors, in particular, how much formula is consumed within a given feed (i.e., measure of satiation) and how much time elapses after the feed until the infant exhibits signs of hunger (i.e., measure of satiety). The investigators will also examine the relationship between the composition of infant formula consumed and infant temperature, activity, sleep, and mothers' perceptions of infants' intake and regulatory behaviors.
