Immunity to disease is a principal aim of hygiene. Natural immunity is rare, but artificial immunity can be acquired through means such as inoculation or vaccination. Inoculation for smallpox was introduced in the early 18th century and later replaced by Edward Jenner's safer method of vaccination using cowpox virus. Diphtheria antitoxin, discovered in 1892, neutralizes diphtheria toxin and has been used to treat and prevent cases of diphtheria.

Diphtheria antitoxin was a significant breakthrough in disease prevention, leading to further research into antidotes for other infectious diseases like tetanus.
Tetanus is a rare but serious disease often occurring among boys during Fourth of July celebrations due to accidents. Proper wound care and understanding the microbe's growth conditions are crucial for prevention.
Asiatic cholera was once greatly feared, but it can be easily prevented with proper hygiene measures similar to those used against typhoid fever.
The plague is a historic epidemic disease still prevalent in parts of Asia. Prevention involves eliminating rats and fleas that transmit the disease.
Key Takeaways
- Inoculation for smallpox was replaced by vaccination using cowpox virus.
- Diphtheria antitoxin neutralizes the toxin produced by diphtheria germs.
- Tetanus prevention involves proper wound care and understanding of microbe growth conditions.
Practical Tips
- Regular revaccination is essential for complete immunity against smallpox.
- Use antiseptics like a solution of corrosive sublimate or carbolic acid to clean minor wounds.
- Maintain hygiene practices to prevent cholera and typhoid fever.
Warnings & Risks
- Inoculation with the actual smallpox virus is dangerous compared to vaccination.
- Failure to properly care for a wound can lead to tetanus infection.
- The plague requires strict measures against rats and fleas in affected areas.
Modern Application
While modern medicine has advanced significantly since this chapter was written, understanding the historical context of disease prevention remains crucial. Vaccination practices have improved safety and efficacy, but the principles remain the same. Proper wound care and hygiene continue to be vital for preventing infections.
Frequently Asked Questions
Q: What is the significance of Edward Jenner's invention in 1796?
Edward Jenner invented vaccination using cowpox virus, which provided a safer method than inoculation with smallpox virus and led to widespread immunity against smallpox.
Q: How does diphtheria antitoxin work in treating diphtheria?
Diphtheria antitoxin neutralizes the toxin produced by diphtheria germs, both in a test tube and in the body of another animal, effectively curing or preventing cases of diphtheria.
Q: What are some preventive measures against tetanus?
Proper wound care is crucial for prevention. Wounds should be cleaned thoroughly with antiseptics like a solution of corrosive sublimate or carbolic acid and kept open to air to prevent the growth of anaerobic bacteria.
