Four industrialized countries need improvement: Austria, Belgium, Ireland and the United Kingdom. Each of them warrants slightly different causes for concern. In Austria, there has been a waning in immunization coverage for all the major vaccines since 1997, with measles at 79 per cent. In Belgium and the United Kingdom, protection against measles has fallen. Belgium reached 90 per cent coverage for measles in 1986 but has not done so since, with erratic performance and no clear sign of progress.
The United Kingdom was consistently immunizing against measles with coverage over 90 per cent in the mid-1990s, but since 1997 has seen a decline in coverage that by 2003 had still not been reversed. Ireland, in contrast, has never yet managed to achieve coverage of 90 per cent of any of the basic vaccines, except BCG, with measles standing lowest in 2003, at 78 per cent.
