Hypothesis
What factors predict the uptake of the A (H1N1) influenza vaccine in the general population of Tokyo?
Conclusion
The uptake of the A (H1N1) influenza vaccine is influenced by factors such as perceived susceptibility to influenza and willingness to pay for the vaccine.
Supporting Evidence
- 38.1% of participants received seasonal influenza vaccine during the preceding season.
- 57.0% had willingness to accept A (H1N1) influenza vaccine at baseline.
- 12.1% had received A (H1N1) influenza vaccine by the time of follow-up.
- People living with underlying diseases were significantly more likely to be vaccinated.
- Perceived high susceptibility to influenza was associated with higher vaccination rates.
Takeaway
This study looked at why people in Tokyo decided to get the A (H1N1) flu shot, finding that those who felt more at risk and were willing to pay for the vaccine were more likely to get vaccinated.
Methodology

Potential Biases
