This is a randomized, blinded, controlled phase II and III clinical trial evaluating the immunogenicity and safety of adsorbed cell-free DPT vaccine. 320 subjects aged 7 years and older in the phase II were divided into two age groups, the ≥18 years group and the 7-17 years group, and randomized 3:1 to receive the trial vaccine Tdcp versus the control vaccine PPV23. 1500 subjects in the phase III were divided into 3 age subgroups. 780 subjects were planned to be enrolled in the 6-year-old group and randomized 1:1 to receive the experimental vaccine Tdcp versus the control vaccine DTaP, and 360 subjects were planned to be enrolled in each of the 7-17 and ≥18 age groups and randomized 3:1 to receive the experimental vaccine Tdcp versus the control vaccine PPV23.
NCT06815250
The goal of this InTroDuce-Programme interventional trial aims to test whether a web-based educational program can improve pregnant women's knowledge about Influenza and Tdap vaccinations and increase their intention to get vaccinated in the future. The main questions it aims to answer are: Does the InTroDuce-Programme increase knowledge and future intention of pregnant mothers to get vaccinated against Influenza and Tdap? How does demographic factors, attitudes and barriers affect vaccination decisions among pregnant mothers? Researchers will compare InTroDuce-Programme to standard care (routine antenatal care) to see if InTroDuce-Programme works to improve knowledge and future intention of pregnant mothers to be vaccinated against Influenza and Tdap. Participants will: Receive the web-based educational module (InTroDuce-Programme), which covers the importance, safety, and effectiveness of vaccinations, as well as addressing common concerns. Be followed up one month after the intervention. Answer questionnaires before and after the intervention to measure changes in vaccination knowledge and future intention to get vaccinated

NCT05457946
The purpose of this study is to evaluate immunogenicity and safety of different doses of candidate hexavalent vaccine in comparison to co-administration of Pentavalent vaccine and Poliomyelitis Vaccine (Inactivated) in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants and thereby to select the optimal dose of candidate vaccine(Stage 1) and to demonstrate lot-to-lot consistency of three lots of LBVD (Stage 2)
NCT01896596
In the UK, infants currently receive a 5-in-1 vaccine (Pediacel) at 2, 3 and 4 months of age, which protects against diphtheria, tetanus, pertussis (whooping cough), polio and Haemophilus influenzae type b (Hib). Infants also routinely receive a meningococcal group C vaccine (MenC) at 3 and 4 months and a 13-valent pneumococcal vaccine (Prevenar13) at 2 and 4 months of age. This study aims to offer infants a 6-in-1 vaccine (Infanrix-Hexa)that also helps protect against hepatitis B alongside the other routine vaccinations in the UK infant immunisation schedule and assess their immune responses to the different vaccines. Hepatitis B virus infects the liver and usually affects adults, but children can be infected through close contact with carriers of the virus. Children with hepatitis B infection may not have symptoms for many years but may go on to develop liver failure, cirrhosis and cancer. Many other countries already use Infanrix-Hexa and this study is being undertaken to help decide whether the UK can do the same. Babies taking part in this study will receive Infanrix-Hexa instead of Pediacel. All other vaccines given will be the same as in the routine schedule but will include one MenC vaccine instead of 2 doses because the UK infant immunisation schedule is soon going to change so that all babies will receive only one MenC vaccine at 3 months of age. There are currently several licensed MenC vaccines that can be given to babies. In order to check whether there are differences in protection, babies taking part will randomly receive one of 3 MenC-containing vaccines: NeisVacC, Menjugate or Menitorix. Studies have already shown that one dose of Neis-Vac or Menjugate given to babies at 3 months provides similar protection against MenC infection as two doses given at 3 and 4 months. Menitorix protects against both Hib and MenC, so babies in the group receiving MenitorixTM will have an extra dose of Hib which is also included in Infanrix-Hexa but might have a lower antibody response to MenC compared to the other two MenC vaccines, although all infants should be well-protected after their 12-month booster vaccinations, which also contain Menitorix.
NCT00228917
This study will be conducted in two stages. In the diphtheria, tetanus, pertussis (DTP) booster phase, subjects will receive a booster dose of Tritanrix-HepB/Hib-MenAC or Tritanrix-HepB/Hiberix (active control) at 15 to 18 or 24 months in a single-blind manner so that the subjects' parents will not know which vaccine was administered to their child. In the Mencevax ACWY phase at 24-30 months, a dose of Mencevax ACWY will be given in an open manner to only those subjects who received less than 4 doses of Tritanrix-HepB/Hib-MenAC. No blood samples will be taken in this safety study.
NCT02096263
The purpose of this study is to assess the immunogenicity and safety of GSK Biologicals' Infanrix hexa vaccine when administered to healthy infants as primary vaccination at 2, 4 and 6 months of age, co-administered with Prevnar and Rotarix with a booster dose of GSK Biologicals' Infanrix and Hiberix vaccines at 15-18 months of age.
NCT04177485
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.
NCT03998215

NCT01090453
This study will evaluate the safety and immunogenicity of GSK Biologicals' GSK2202083 vaccine co-administered with Prevenar 13® at 2, 4 and 12 months of age and with Rotarix™ at 2 and 4 months of age.
NCT00282295
New immunization recommendations in the US include vaccination of adolescents against pertussis and meningococcal disease. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention recommends that Tdap (Tetanus Toxoid, Reduced Diphtheria Toxoid And Acellular Pertussis Vaccine Adsorbed) and MCV4 (Meningococcal conjugate vaccine against serotypes A, C, Y and W-135) vaccines be administered to adolescents at the same office visit if vaccination with both vaccines is indicated. Therefore, this study is designed to evaluate the safety and immunogenicity of a booster vaccination with Boostrix co-administered with Menactra as compared to the administration of either vaccine alone in healthy adolescents 11 - 18 years of age.
NCT00317187
The purpose of this study is to compare the reactogenicity \& safety of Tritanrix™-HepB/Hib-MenAC vaccine to the international standard of care, Tritanrix™-HepB/Hiberix™.
NCT03552445
