Developments in influenza vaccination coverage in England, Scotland and Wales covering five consecutive seasons from 2001 to 2006.

This study aims at assessing trends in influenza vaccination coverage from 2001 to 2006 in Great Britain, at understanding drivers and barriers to vaccination and at identifying vaccination intentions for influenza season 2006/2007. In seasons 2001/2002 to 2005/2006, telephone-based household surveys representative of the population from age 16 were conducted, with about 2000 interviews per season (10,095 in total). Overall influenza vaccination coverage rate in Great Britain reached 25.9% in season 2005/2006. A sub-analysis showed that the highest coverage was reported in Wales reaching 33.3%. In the elderly recommended vaccination (from age 65), the coverage reached 79% in 2005/2006. Advice from the family doctor and the perception that influenza is a serious illness were the most frequent reasons for getting vaccinated. The most frequent reasons for not getting vaccinated, in persons never vaccinated before, were that they had not considered immunisation or had not received a recommendation from their family doctor. Those vaccinated in the past but not in the current season said they had not thought about vaccination/forgot. A gap continues to exist between those with intention to get vaccinated and those actually vaccinated, indicating a potential to increase vaccination coverage rate in the future. Our study shows that stable vaccination coverage rates were observed from 2002 to 2006 in Great Britain. The coverage had increased in Wales and in Scotland. The coverage among the elderly above 65 years was the highest in Europe. Although Great Britain complies with national and international goals of vaccination coverage rates effort is needed to ensure high vaccination coverage rates at the same level in the future.
