Active clinical trials for "Poliomyelitis"

The purpose of the study is to evaluate safety and immunogenicity of inactivated poliomyelitis vaccine based on Sabin strain (LBVC) in healthy infants to select optimal dose of LBVC as well as to demonstrate the lot-to-lot consistency and non-inferiority of LBVC.

A dose escalating study with 3 different dosing regimens of the studied vaccine (IPOVAC- POLYVAC-Vietnam) and a licensed vaccine (IMOVAC-Sanofi Pasteur- France) is conducted in Vietnamese children, aged 2 months and above to assess the safety and immunogenicity. Two hundred and forty children are enrolled and placed randomly into 4 groups (60 children/group), each of which receive 3 doses of vaccine subcutaneously, at 4 week interval. Safety issues included immediate reaction at the site of injection and systemic reaction within 30 min of administration, within 7 days after each dose, unexpected event occur within 30 days of each dose, SAE (from start of dose 1 to 30 days after dose 3), blood cell count, urea, ALT,AST. Immunogenicity outcomes include seroconversion of neutralising antibodies for each of vaccine serotypes.

The purpose of this study will be to evaluate whether a bivalent oral polio vaccine (bOPV) manufactured by Beijing Bio-Institute Biological Products Co., Ltd (BBIBP) has a similar immunogenicity profile to a WHO prequalified bOPV.

The study will assess and compare the immune response to full-dose inactivated polio vaccines (IPV) via intramuscular (IM) administration and of the fractional dose of inactivated poliovirus vaccine (f-IPV) via intradermal (ID) administration, in different schedule combinations in the Expanded Program on Immunization (EPI) primary series.

This is a single-center, randomized, active-controlled, parallel-group, open-label, phase I study to evaluate safety and immunogenicity of single injection of LBVD or Eupenta co-administered with Imovax Polio in healthy adults.

The overall goal of this study is to identify interference between intramuscular Inactivated Polio Vaccine (IPV) and other vaccines (Measles Rubella and Yellow Fever) co-administered at nine months of age and to confirm the safety of co-administration. In addition, the study will compare the immunogenicity and safety of IPV when administered via different routes. A total of 1504 healthy infants between the ages of nine to ten months, who have completed their primary immunizations, including at least three doses of trivalent Oral Polio Vaccine (tOPV) will be recruited for this study.

This is a follow-up of the primary series vaccination schedule in Study A3L24 (NCT01177722) and booster vaccination in Study A3L27 (NCT01444781). Study Objective: To describe the long-term antibody persistence at 3.5 and 4.5 years of age following a 3-dose primary series vaccination of either DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) +Rotarix™ or Infanrix hexa™+Prevenar™ (PCV7) +Rotarix™ vaccination at 2, 4, 6 months of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) or Infanrix hexa™+Prevenar™ (PCV7) at 12 to 24 months of age. Observational Objectives: To describe the long-term antibody persistence by group and by stratification on the age at inclusion of the A3L27 booster study. To describe the effect of one additional oral dose of stand alone poliovirus isotypes 1, 2 and 3 vaccine* on the antibody persistence immune response for poliovirus isotypes (4 vs 5 doses of poliovirus administered).

The aim of the study is to assess the immunogenicity of SP059 (IMOVAX POLIO®: Inactive Poliovirus Vaccine) vaccine against poliovirus and safety after fifth dose. Primary Objective: To investigate the booster vaccine response rate against poliovirus types 1, 2 and 3 one month following the vaccination dose with SP059 as 2nd booster Secondary Objectives: To investigate seroprotection rates (percentage of subjects presenting poliovirus neutralizing antibody titers above 1:8 (1/dil.) at pre- and post-booster time points, Geometric mean titers (GMT) at pre- and post-booster time points and geometric mean of individual titer ratio (GMTR). To investigate the safety after dosing of SP059 as 2nd booster.

PRIMARY OBJECTIVES To describe in 11 to 13-year-old children previously vaccinated with either REVAXIS or DT Polio at 6 years of age the antibody persistence against diphtheria, tetanus, and poliovirus types 1, 2 and 3 To describe one month after a booster dose of TETRAVAC-ACELLULAIRE the immune responses against diphtheria, tetanus, and poliovirus types 1, 2 and 3 SECONDARY OBJECTIVES To describe other parameters of the antibody persistence against diphtheria, tetanus and poliomyelitis antigens To describe other parameters of the immune responses to diphtheria, tetanus and poliomyelitis antigens one month after a booster dose of TETRAVAC-ACELLULAIRE To describe the safety profile of a booster dose of TETRAVAC-ACELLULAIRE

Chronic malnutrition is associated with lack of effective gut immunity which is a possible explanation for why we see polio cases among a proportion of children who have received 7 or more doses of OPV.Our proposed idea is to evaluate if IPV antigen given later in life may act together to boost humoral and mucosal immunity in children belonging to low-income background in Karachi who have moderate to severe chronic malnutrition (height for age Z score less than -2SD). We also intend to compare eIPV + OPV with OPV only in non-malnourished infants at 9 -12 month of age. Thus, the proposed study is a combination of two trials, with study population stratified by nutritional status, each with a reference arm (bOPV) and an experimental arm (bOPV plus IPV).
