High vaccination rates for seasonal and pandemic (A/H1N1) influenza among healthcare workers in Dutch general practice

In previous years, the influenza vaccination rate among Dutch general practitioners (GPs) was low (36% during the 2007/2008 season). Since 2008, yearly influenza vaccination has been actively recommended for GPs in The Netherlands. Moreover, in 2009 the Dutch government urged healthcare workers to receive additional vaccination against the pandemic influenza (A/H1N1). The effects of these recommendations are unknown. In February 2010, a questionnaire was mailed to random samples of GPs (n=810) and GP-trainees (n=300). Vaccination rates were determined and motives and barriers for vaccination were assessed. The response rates for GPs and GP-trainees were 83% and 90%, respectively. In total, 63% of the GPs were vaccinated against seasonal influenza and 85% against pandemic (A/H1N1) influenza. For GP-trainees, these percentages were 47% and 77%, respectively. With regard to the medical staff working in the respondents' practices, 60% received the seasonal and 76% the pandemic (A/H1N1) influenza vaccine. Reducing the risk of transmitting the virus to vulnerable patients and the individual's personal protection were the most frequently reported motives for vaccination. Having no medical indication for influenza vaccination and the conviction of being protected against influenza because of frequent professional exposure to the virus were the most frequently mentioned reasons for not being vaccinated. In conclusion, the seasonal influenza vaccination rate among Dutch GPs has risen considerably since the previous survey and the vaccination rate against pandemic (A/H1N1) influenza was very high. Moreover, Dutch GPs were convinced that influenza vaccination will reduce the risk of transmitting the virus to their patients.
