In June 2003 a questionnaire on immunisation training was sent to the 302 primary care trusts (PCTs) in England to ascertain the frequency and content of immunisation training being offered to healthcare professionals. Fifty-four per cent of the 227 trusts (75%) who replied were concerned about their ability to deliver an immunisation programme. Contributing factors included the lack of a designated training lead, shortage of specialist input, available time, and funding. Of PCTs, 33/219 (15%) were not providing immunisation training sessions for practice nurses, 28/219 (13%) for health visitors, and 30/219 (14%) for school nurses; 67/219 (31%) had no sessions organised for general practitioners. Most 138/175 (79%) PCTs would welcome the introduction of some national minimum standards for immunisation training to assist them in setting up and maintaining a programme, and allocating sufficient resources to it.
