Hypothesis
Is there a link between flu vaccination and olfactory impairment in older adults?
Conclusion
Flu vaccination may help protect against olfactory loss in older adults, particularly in men and white individuals.
Supporting Evidence
- Olfactory impairment is common in older adults.
- Flu vaccination was associated with better olfactory function.
- The study adjusted for demographics and health status.
Takeaway
Getting a flu shot might help older people keep their sense of smell better.
Methodology

Potential Biases
