Seasonal epidemics of influenza occur annually in the United States. Each year in the U.S. influenza causes:
- Thousands to tens of thousands of deaths
- About 200,000 hospitalizations
- 111 million workdays lost
- $7 billion in sick days and lost workplace productivity
The vaccine protects about 70 of every 100 people who receive it from getting really sick, preventing many hospitalizations and deaths.
