Study information

Study designClinical trial, evaluation based, randomised double blind trial
Primary study designInterventional
Secondary study designRandomised controlled trial
Study setting(s)Not specified
Study typePrevention
Scientific title
Study objectivesOne dose of monovalent oral poliovirus vaccine induces higher levels of seroconversion against poliovirus type 1 when compared to trivalent oral poliovirus vaccine.

Please note that as of 18/10/2007 the anticipated start and end dates of this trial were modified, the initial trial dates were as follows:
Anticipated start date: 15/07/2005
Anticipated end date: 31/07/2006
Ethics approval(s)Ethics approval received on the 28th June 2005.
Health condition(s) or problem(s) studiedPolio
InterventionOne dose of monovalent oral poliovirus vaccine compared to trivalent oral poliovirus vaccine.

Measurements:
1. Cord blood will be collected immediately after birth
2. 30 days after birth, second sample of blood collected by heel stick method and a stool sample taken
3. Four additional stool samples collected on a weekly basis at 7, 14, 21, and 28 days after birth
4. 60 days after birth, third sample of blood collected by heel stick method
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Oral poliovirus
Primary outcome measureTo demonstrate the superiority of one dose of mOPV1 compared with tOPV by assessing:
1. Humoral Immunity - one dose of mOPV1 induces significantly higher levels of seroconversion against poliovirus type 1 than does one dose of tOPV
2. Mucosal Immunity - one dose of mOPV1 significantly reduces excretion of poliovirus type 1 after a mOVP1 challenge than following one dose of tOPV
Secondary outcome measuresThe secondary endpoint is prevalence of excretion of poliovirus type 1 in stool specimens 7 days post-challenge with mOPV1 at age 30 days + 7 days. Additional endpoints will be prevalence of excretion in 4 weeks after mOPV1 challenge by vaccination group; and seroconversion at 60 days after 2 doses of mOPV1 (no control available).
