We analyse the determinants of influenza vaccination take-up of Europeans above the age of 50 years using the first two waves of the Survey of Health, Ageing, and Retirement (SHARE). Using quality-of-care indicators, special emphasis is put on the measurement and the impact of physician quality. We find that age, health status, lifestyle, labour-force status, and the family structure are important determinants of the decision to get a flu shot. Physician quality, as measured by four indicators, also positively affects the probability of getting a flu shot. Copyright © 2010 John Wiley & Sons, Ltd.
