Swine flu vaccine must be free and safe for high uptake
- EurekAlert
- 09/10/27 05:00
Almost half of adults surveyed in summer 2009 in Hong Kong say they would take up free swine flu vaccination. However, this figure drops to around 1 in 7 if the price they have to pay for the vaccine reaches $26. In the absence of proved efficacy and safety, the figure decreases to less than 1 in 20, according to one of the first studies on behavioral intentions and A/H1N1 vaccination, published...
