Scientific title
Study objectives1. Does a schedule of three fractional 0.1 ml IPV doses administered intradermally (intervention) provide comparable seroconversion and titre with a three-dose schedule of full 0.5 ml IPV doses (control) administered intramuscularly at 2, 4, and 6 months?
2. What is the contribution to seroconversion and titre in each group after the first, second and third dose of study vaccines?
3. What is the influence of maternally-derived antibodies on seroconversion and titre?
4. Does each study arm have comparable adverse events - systemic and local (the intervention group receives fractional doses by needle-free device, while the control group receives full doses by intramuscular injection by needle and syringe)?
5. Is resistance to excretion of poliovirus type 1 (an indication of mucosal immunity) following a challenge dose with monovalent type 1 Oral Poliovirus Vaccine (mOPV1) similar among the two study groups?
Ethics approval(s)Ethics approval received from:
1. World Health Organization (WHO) Research Ethics Review Committee on the 29th January 2007 (ref: RPC189)
2. Ethical Review Committee of the Ministry of Health, Muscat, Oman on the 30th August 2006 (ref: 502)
Health condition(s) or problem(s) studiedPoliomyelitis vaccination
InterventionPatients will be randomised between:
1. A fractional dose of IPV (0.1 ml or 1/5 of a dose) administered intradermally by needle-free device - potency of IPV is 40-8-32-D antigen units
2. A full dose of IPV (0.5 ml) administered intramuscularly by needle and syringe - potency of IPV is 40-8-32-D antigen units
