Active clinical trials for "Poliomyelitis"

This study will assess both the antibody persistence of the investigational vaccine and the immune response and safety of a booster dose of PENTAXIM™ vaccine in 18 months-old toddlers who participated in an earlier study in order to determine if they are still protected before they receive a booster dose of D, T, IPV, pertussis or Hib vaccines and also to assess the quality of the induced immune memory in response to a booster dose of the same vaccine as in the primary series. Primary Objective: To describe the antibody persistence at 18 months of age and the booster effect of a dose of PENTAXIM™ on immunogenicity. Secondary objective: To describe the safety profile of the booster dose PENTAXIM™ in each vaccine group defined by the vaccines received during the primary series.

The purpose of this study is to evaluate safety and immunogenicity of Pediacel® in infants and toddlers when given at 2,3,4 and 12-18 months of age. Primary Objectives: To compare the post-dose 3 immunogenicity of Pediacel® to Infanrix®-IPV+Hib when both are co-administered with Prevenar®. To describe the post-dose 3 pertussis antibody responses. Secondary Objectives: To compare the post-dose 4 immunogenicity of Pediacel® to Infanrix®-IPV+Hib when both are co-administered with Prevenar®. To describe the safety after each vaccination following co-administration with Prevenar®.

The purpose of this study is to evaluate the safety of Sabin Inactivated Poliovirus Vaccine (Vero cell)(sIPV)in the primary immunization of infants at the age of 2 months and booster immunization of children at the age of 18 months, and the simultaneous immunization with other vaccines of children at the age of 2 months and older, so as to provide reference for the improvement of immunization strategy.

This Phase III study has been designed to compare the SII Inactivated Salk Polio Vaccine (Adsorbed) with Sii licensed IPV by testing the vaccine in infants (three doses administered 4 weeks apart, starting at 6-8 weeks of age) in order to demonstrate the non-inferiority in the induction of specific poliovirus neutralizing antibody (PVNA) to poliovirus type 1, type 2 and type 3 by these vaccines. The study will also evaluate lot-to-lot consistency in the manufacture of SII Inactivated Salk Polio Vaccine (Adsorbed) by demonstrating equivalence in the induction of PVNA across three production lots.

This is a phase IV open-label randomized clinical trial that will compare intestinal and humoral immunity in infants receiving inactivated poliovirus vaccine (IPV) and two or three doses of bivalent oral poliovirus vaccine (bOPV).

A Phase 4 study to evaluate the safety and immunogenicity of monovalent oral polio vaccine type 2 in healthy IPV-vaccinated children aged 1 to 5 years in Lithuania.

The objective of this study is to assess the immunogenicity and safety of the DTaP-IPV combination vaccine compared with those of separate DTaP and IPV vaccines administered to healthy infants at 2, 4, and 6 months of age.

The background of the present clinical trial is the overall aim of the World Health Organization (WHO) to obtain eradication of polio in the world. As part of this overall plan, inactivated polio vaccine (IPV) against poliovirus types 1, 2 and 3, at an affordable price, needs to be available in low resource third world countries. The intention of the present phase II clinical trial is to determine if reduced dose(s) of IPV-Al SSI are safe in the target population and do not decrease the immunogenicity clinically significantly compared to full dose IPV Vaccine SSI. The infants will receive three doses of one of the trial vaccines according to the WHO Expanded Program on Immunization (EPI) schedule of 6, 10 and 14 weeks of age. A total of 824 healthy infants will be included in the trial.

The purpose of this study is to determine whether a lower dose of inactivated polio vaccine (IPV) injected into the skin (intradermal administration) can work equally well or better than the standard dose injected into the muscle (intramuscular administration). There are more immune cells in the skin than in the muscle, and other vaccines have been shown to require a lower dose when administered intradermally. The study is being done in participants infected with HIV because HIV-infected people are known to respond less well to vaccines than other groups, so it is particularly important to know if IPV might work better in HIV-infected people if administered intradermally. If it is possible to lower the dose of IPV by intradermal administration, this would make inactivated polio vaccine more affordable in the developing countries where it is most needed

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.
