| pubmed-article:15779792 | pubmed:abstractText | In December 2001, an increase in cases of hepatitis A was observed in South Yorkshire. Cases were predominantly young males who reported injecting drug use. A community-based vaccination programme was introduced in November 2002, but new cases continued to occur. In March 2003, a vaccination campaign was implemented in the local prison for a four-week period. One thousand two hundred and thirty-six (91%) prisoners were vaccinated. Two thirds (895/1,363) of the prisoners came from the area affected by the outbreak and 52% (465/895) reported injecting drugs. The median age of injectors was 25 years. Notifications of cases of hepatitis A from South Yorkshire ceased in August 2003. Although on this occasion the prison vaccination campaign was probably implemented too late to have had a significant impact on the local outbreak, a large number of young male injectors from the local area were successfully vaccinated. This suggests that a prison-based intervention offers a potentially effective way of immunising the IDU population and interrupting a community-based outbreak. | lld:pubmed |
