A tetanus shot is virtually 100% effective when a complete vaccine series is administered.
While no vaccine offers an absolute guarantee of protection, the tetanus vaccine is highly effective at preventing tetanus infection. The reference indicates a clinical efficacy of "virtually 100%," meaning it's extremely close to perfect protection against tetanus.
Here's a breakdown:
- High Efficacy: The tetanus vaccine is one of the most effective vaccines available.
- Complete Series: The "virtually 100%" efficacy is associated with completing the recommended vaccine series.
- Boosters: Periodic booster shots are crucial to maintain immunity against tetanus throughout life.
- Real-World Protection: While theoretically not exactly 100%, for practical purposes, a fully vaccinated individual has an extremely low risk of contracting tetanus.
| Vaccine | Clinical Efficacy |
|---|---|
| Tetanus | Virtually 100% |
| Diphtheria | 97% |
