Active clinical trials for "Whooping Cough"

The aims of this study are to evaluate the safety and immunogenicity of a booster dose of GSK Biological's candidate Tdap vaccine containing 0.3 mg Al when administered to healthy school children and adolescents (9-13 years of age) previously vaccinated with five consecutive doses of Pa-containing vaccine. The inclusion of hepatitis A vaccine (Havrix®) as a control vaccine enables this study to be conducted in a double-blinded in terms of immunogenicity and safety assessments.

This study will evaluate the safety and immune response to GlaxoSmithKline Tdap vaccine compared to licensed Td vaccine when used as a booster in healthy adolescents (10-18 years of age).

OBJECTIVES General: To investigate the immunological background for the non-specific effects of diphtheria-tetanus-pertussis (DTP) and measles vaccines on child mortality Specific: Examine the cytokine responses and possible association with morbidity in a study of DTP vaccinated children who will be randomised to receive a measles vaccine or no vaccine at 4½ months of age. (All children will receive a measles vaccine at 9 months of age)

The purpose of the study is to support the recommendation of vaccination of all pregnant women in Colombia with Diptheria, tetanus and pertussis (dTpa) by studying the transfer of pertussis specific IgG antibodies from mother to the child.

The study is a Phase I, first in human, monocenter study, aiming at assessing the safety and immunogenicity of a genetically detoxified pertussis toxin (PT) when administered via the cutaneous route with Viaskin patches to healthy volunteers at 2 different doses of 25 mcg or 50 mcg PT protein compared to Viaskin placebo. Two cohorts of 30 subjects will be successively enrolled. Safety of the product will be assessed throughout the 10-week study and its immunogenicity will be assessed at regular intervals with collection of blood samples for immunological analyses. Four weeks after the second Viaskin application (at Day 42 of the study), all subjects will receive a dose of diphtheria-tetanus-pertussis vaccine (Boostrix® dTpa) to ensure the optimal recall of their immunity against pertussis.

Randomized controlled trial of 2 strategies to provide adults with the Tdap vaccine to patients presenting to the emergency department. Rates of vaccination as well as effects on department efficiency will be measured.

The purpose of this protocol is to generate a set of data that will be analysed by integrated systems biology approach, for validation in subsequent clinical trials or in animal models. 240 healthy participants (18-45y) will be enrolled, 200 will be administered a dose of Boostrix on Day 0, 20 will receive a placebo on Day 0.

The primary research aim of this project is to test the effectiveness of a comprehensive, evidence-based vaccine promotion package implemented in the obstetric setting on increasing the likelihood that a pregnant woman in Georgia will receive an influenza and/or pertussis vaccine.

The purpose of this study is to evaluate the persistence of immune response against the three pertussis antigens (anti- pertussis toxoid (PT), anti-filamentous hemagglutinin (FHA) and anti-pertactin (PRN)) in subjects who received a booster dose of either aP or Tdap study vaccines or Boostrix® during V113_01 study. There was only one Clinic Visit at day 1. Eligible subjects went undergo a single blood draw after which they were observed for approximately 15 minutes. Approximately 10.0 mL of blood was withdrawn. No vaccine was administered and no safety data was collected in this study.

The purpose of this study is to perform an epidemiological survey of the adult population in Hungary to calculate the seroprevalence of pertussis.
