Filter by:This is a phase 1/2, single-centre, double-blind, double-dummy, randomized, active-controlled, age de-escalation trial. Age de-escalation will be based on a review of the safety data from the preceding cohort (adults for toddlers and toddlers for infants) up to day 14 post study product administration by a data monitoring committee (DMC). All participants will receive either the MRV-MNP and a placebo (0.9% sodium chloride) SC injection (PLA-SC) or a placebo-MNP (PLA-MNP) and MRV by the SC route (MRV-SC). Only those study staff randomizing participants and preparing the study products for administration will be aware of the products administered. Those administering the study products, all other trial staff and the participants and parents will be blinded to treatment group. 45 adults (18 to 40-years-of-age) will be randomized in a 2:1 ratio. Thus, 30 adults will receive MRV-MNP and PLA-SC while 15 adults will receive MRV-SC and PLA-MNP. 120 toddlers (15 to 18 months-of-age) will be randomized in a 1:1 ratio. Thus, 60 toddlers will receive MRV-MNP and PLA-SC while the same number of toddlers will receive MRV-SC and PLA-MNP. 120 infants (9 to 10 months) will also be randomized in a 1:1 ratio. Thus, 60 infants will receive MRV-MNP and PLA-SC while the same number of infants will receive MRV-SC and PLA-MNP. Solicited local and systemic AE will be collected daily from all participants from the day of study product administration to day 13 post study product administration. Unsolicited AE and SAE will be collected from the day of study product administration to day 180 post study product administration. All participants will have laboratory investigations (hepatitis B, hepatitis C, hematology and biochemistry) conducted as part of screening. Adults will have safety laboratory investigations repeated on day seven and day 14 post study product administration. Toddlers and infants will have safety laboratory investigations repeated on day seven post study product administration. All participants will have measles- and rubella-specific SNA titers and measles- and rubella-specific IgG concentrations measured at baseline and day 42 and 180 post study product administration. Other Expanded Program on Immunization (EPI) vaccines due in toddler (oral poliovirus vaccine, diphtheria-tetanus-pertussis) and in infants (oral poliovirus vaccine, yellow fever vaccine and MenAfriVac® [due at 12 months]) will be given by the investigator team at the day 42 study visit (V4).
Till now, mortality reports among children below 9 years remains extremely low despite that the incidence of death toll is high and exceeding 50,000 patients among older population, One speculation for lower SARS infectivity is that cross-protective antibodies against measles vaccine ( MV). In mice susceptible to measles virus, recombinant MV induced the highest titers of neutralizing antibodies and fully protected immunized animals from intranasal infectious challenge with SARS-CoV, The primary objective of the present study is to determine the benefit of measles vaccine in health care professional to decrease the incidence of COVID-19. We Hypothesized that, measles vaccine may lower the incidence of serologically proven SARS-CoV-2 infection and reported respiratory illness
In addition to protecting against measles infection, measles vaccine (MV) strengthens the individual's ability to combat infections in general - MV has beneficial non-specific effects (NSE) lowering the risk of death and admissions by around 30%. In Guinea-Bissau 30% of children do not receive a routine MV scheduled at 9 months of age, putting both the individual child's health and measles eradication at risk. WHO recommends vaccination at health system contacts, including those for curative services. At the paediatric ward of the national hospital in Guinea-Bissau, there are more than 2600 yearly contacts with measles-unvaccinated children aged 9-59 months, but no vaccines are given. In a randomised controlled trial, we will assess the effect of providing MV vs placebo to 5400 children at hospital contacts (at discharge or after an out-patient consultation) to test the hypothesis that MV reduces the risk of admission or death (composite outcome) by 25% over the subsequent 6 months.
Thus study is a clinical trial for Measles and Rubella vaccine that will be used inIndonesian National Program of Immunization. The study design will be randomized, observer blind, prospective intervention study.
Faced with high rates of immunization drop-out, Uganda's immunization program requires innovative approaches to address this weakness. Building upon Uganda's growing mHealth infrastructure to pilot a scalable short message service (SMS) system to remind caregivers of their children's upcoming vaccination visits, it was hypothesized that the SMS intervention will increase immunization coverage in a cost-effective and affordable manner that would make it scalable. The study design was an investigator-blinded, multi-center, parallel groups randomized controlled trial with randomization occurring at the caregiver level in select health facilities of Arua District in Uganda. Enrollment took place at the time of Pentavalent 1 vaccination, and both arms included standard of care provided by the health worker. However, in the intervention arm, caregivers also received SMS text messages reminding them to return for their children's second and third doses of Pentavalent vaccine (four and eight weeks after the first dose of Pentavalent vaccine) and measles-containing vaccine (9 months of age). The primary outcome of interest is vaccination coverage at 12 months of age among children enrolled in the study and will be measured by comparing Penta3 and MCV coverage between arms. The study will also examine the SMS impact on timeliness of vaccine receipt, as it is hypothesized that those children receiving the SMS intervention will be more likely to have timely vaccination than those in the control group. The study will also assess caregiver acceptability and cost-effectiveness of the SMS intervention. In addition to assessing its impact on strengthening the immunization program, this intervention has implications for strengthening other programs of the health system through similar health messaging directed toward caregivers.
IDinsight is conducting a randomized controlled trial to assess the impact of various sized cash incentives for caretakers of infants that require a 9-month measles vaccination on the completion rate for the vaccine in Nigeria. The purpose of the experiment is to help New Incentives (NI) determine the optimal size of the incentive as they scale to the North West region of Nigeria.
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.
to assess safety and immunogenicity of measles-rubella (MR) routine immunization in Indonesian Children and Infants
The world is set on eradicating measles and polio infections in the coming decade. Once both infections are under control, campaigns with measles and oral polio vaccines will be phased out. This might do more harm than good for child survival in low-income countries. Studies from the Bandim Health Project in Guinea-Bissau, and elsewhere, have revealed, that the live measles and oral polio vaccines have beneficial non-specific effects, i.e. effects on child morbidity and mortality unrelated to prevention of the targeted diseases. The campaigns are presumed to be most beneficial for children not reached by routine vaccination programs, as they are not already protected. However, studies show that prior routine or campaign vaccination may boost resistance against unrelated infections. If we phase out measles and oral polio campaigns after eradicating their target infections without considering the impact on child survival, the drastic decline in child mortality since 1990 could change direction. We will conduct the first cluster randomized controlled trial to evaluate the effect of measles and oral polio campaigns on general child morbidity and mortality via the Bandim Health Project. Bandim Health Project runs a Health and Demographic Surveillance System in Guinea-Bissau since 1978 and assesses child health interventions' real-life effects, via continuous registration of all interventions given to all children, and follow-up of individuals. We will conduct the trials in rural Guinea-Bissau monitoring all nine health regions. The hypotheses are: RECAMP-MV: Measles vaccination campaign in Guinea-Bissau reduce morbidity and mortality among children between 9 and 59 months of age by 80% during the subsequent 18 months in a context of limited measles infection. RECAMP-OPV: Oral polio vaccination campaigns in Guinea-Bissau reduce morbidity and mortality among children between 0 and 8 months of age by 25% during the subsequent 12 months in a context with no polio infection. Originally, the trials were meant to be implemented in 182 clusters, enrolling 21000 children. Following revised sample size calculations and discussions with the Data Safety and Monitoring Board, the number of clusters were increased to 222 and the planned number of enrolments increased from 21,000 to 28,000 (RECAMP-MV: 18000, RECAMP-OPV: 10000). To explore the hypothesis that at least part of the beneficial non-specific effects of OPV is driven by changes in the gut and/or respiratory microbiome, we will collect microbiome samples in a sub-group: A nasal swab and a rectal swab will be collected from 50 infants allocated to the intervention group, and 50 infants allocated to the control group. Two sample will be collected for each infant one when recruited for RECAMP-OPV and a second two months later.
This trial will evaluate the safety and immunogenicity of: i) measles vaccine (CAM-70) after primary dose at 6 months (MV1) and booster vaccination at 12 months (MV2); ii) a single dose of varicella vaccination at 18 months; and iii) a single dose of hepatitis-A vaccination at 18 months in HIV-exposed and HIV-unexposed South African children.
