Influenza vaccination coverage rates in Europe--covering five consecutive seasons (2001-2006) in five countries

OBJECTIVE

To understand potential drivers and barriers to influenza vaccination in the general population.

METHODS

47 982 household surveys were conducted in five European countries between 2001 and 2006.

RESULTS

Overall influenza vaccination coverage increased over the years and reached 26.2% in 2005/06. Among the elderly > or =65 years, the rate increased significantly to 67.8% (2005/06). The most common reason for being vaccinated over the 5 years was the perception of influenza as a serious illness, which people want to avoid. The main reason for not getting vaccinated among those never previously vaccinated was feeling that they were unlikely to catch influenza. A recommendation by the family physician was the most encouraging factor for vaccination.

Increasing influenza vaccination coverage in recommended population groups in Europe

The clinical and economic burden of seasonal influenza is frequently underestimated. The cornerstone of controlling and preventing influenza is vaccination. National and international guidelines aim to implement immunization programs and targeted vaccination-coverage rates, which should help to enhance the vaccine uptake, especially in the at-risk population. This review purposes to highlight the vaccination guidelines and the actual vaccination situation in four target groups (the elderly, people with underlying chronic conditions, healthcare workers and children) from a European point of view.

Universal influenza vaccination: the time to act is now

Annual influenza epidemics create a significant public health burden each year in the United States. That influenza continues to pose a public health threat despite being largely preventable through vaccination is indicative of continuing weaknesses in the U.S.'s public health system. Moreover, the burden of annual influenza epidemics and the fragility and instability of the capacity to respond to them underscore the U.S.'s ongoing vulnerability to pandemic influenza and highlights gaps in bioterrorism preparedness and response efforts. This article examines the burden of annual influenza epidemics in the U.S., efforts to combat that burden with vaccination, shortcomings of influenza vaccination efforts, and how those shortcomings exemplify weaknesses in pandemic influenza and bioterrorism preparedness efforts. We make the case for establishing an annual universal influenza vaccination program to assure access to influenza vaccination to anyone who can safely receive vaccination and desires it. Such a program could greatly reduce the annual burden of influenza while advancing and maintaining U.S. pandemic influenza and bioterrorism preparedness and response efforts.

Influenza vaccination coverage and reasons to refrain among high-risk persons in four European countries

This paper examines influenza vaccine coverage using a population base of an average of 2300 persons in each of four European countries (Germany, Spain, Poland and Sweden). The reasons for non-vaccination of those in the high-risk groups were explored by questionnaire. The vaccine coverage rate (VCR) for elderly ranged from 18% in Poland to 67% in Spain. The VCR for high-risk population under 65 was 10% in Poland, 13% in Sweden, 27% in Germany and 30% in Spain. The most important reasons mentioned for not being vaccinated were: perceived sufficient resistance to flu (33-42%) in all countries; financial barriers in Poland (25%), and not to qualify for the vaccination (30%) and forgetfulness (20%) in Germany. Receiving a personal invitation for the vaccination, results in higher coverage rates in all four countries. We think that future interventions could be directed towards: an information campaign with special attention to the high-risk groups due to disease; promotion of personal invitations; and, for Poland, solving financial barriers to vaccination.
