Study hypothesis
When giving routine immunisations to infants, does the needle size used to administer the vaccines affect the serum antibody responses and/or the incidence of local and general reactions.
Ethics approval
This study was approved by the Mid and South Buckinghamshire and Oxfordshire local research ethics committees.
