Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Term babies born by elective caesarean section are randomised to recieve routine intramuscular monovalent hepatitis B immunisation (0.5mL of H-B-Vax II, CSL Biotherapies/Merck & Co Inc, containing 5 micrograms of hepatitis B surface antigen adsorbed onto 0.25 mg of aluminium hydroxide in 0.5 mL) either at 24 or after 96 hours of age. Daily CRP levels are taken at 24, 48, 72 and 96 hours. Administration of vaccine at either 24 or 96 hours is within standard practice.
Intervention code [1] 257836 0
Early detection / Screening
Comparator / control treatment
All babies recieve standard treatment, namely immunisation with monovalent hepatitis B vaccine within the first week of life. In one group (the control group) vaccine is given slightly later. The comparison is the effect on CRP concentrations between normal dose and no dose of hepatitis B vaccine in the first 96 hours of life.

Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At 24 hours of age, babies were randomised to a treatment group by opening sequentially numbered opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation sequence was developed before the start of the study by placing a single slip of paper labelled either Immunisation or Control (6 slips, 3 of each treatment, block length 6) into each of 6 identical opaque envelopes, sealing the envelopes, shuffling and then numbering the envelopes sequentially. The process was repeated in blocks of 6 until the required total number of envelopes (40 envelopes numbered 1-40) was assembled.
