Nov. 13, 2007 -- Most vaccine-preventable diseases are rarer than ever in the U.S., CDC researchers reported today.
They tracked reported cases, deaths, and hospitalizations for 13 diseases that have vaccines recommended by the CDC since before 2005.
Consider these findings from 2006:
- A 92% drop in cases and 99% or greater drop in deaths for diphtheria, mumps, pertussis (whooping cough), and tetanus, compared to pre-vaccination days.
- Smallpox has been eliminated worldwide.
- Polio has been eliminated in the U.S.
Newer vaccines are also making a dent in diseases. Here's a quick look at how cases have declined since the CDC recommended vaccines against these diseases:
- Invasive Haemophius influenzae type b (Hib): cases down nearly 100%
- Hepatitis A: cases down 87%
- Hepatitis B: cases down 80%
- Invasive pneumococcal disease: cases down 34%
- Varicella (chickenpox): cases down 85%
The researchers -- who included Sandra Roush, MT, MPH -- don't want anyone taking that progress for granted.
