Actually, to be fair, whilst mass vaccinations will have likely mopped up the final percentage fall on mortality rates, I would not be surprised if the vast majority has been achieved by potable water, better diet and effective sewage treatment.

I don't know what percentage to apply to which improvement as they came about concurrently. If it is your child it matters not if they are saved by vaccination or the operation of the water department or who gets the credit.

Death in Childhood Is No Longer Expected

In 1900, 30 percent of all deaths in the United States occurred in children less than 5 years of age compared to just 1.4 percent in 1999 (CDC, 1999a; NCHS, 2001a). Infant mortality dropped from approximately 100 deaths per 1,000 live births in 1915 (the first year for which data to calculate an infant mortality rate were available) to 29.2 deaths per 1,000 births in 1950 and 7.1 per 1,000 in 1999 (CDC, 1999b; NCHS, 2001a).2

This decrease in mortality reflects a century's worth of advances in public health, living standards, medical science and technology, and clinical practice. Many infants who once would have died from prematurity, complications of childbirth, and congenital anomalies (birth defects) now survive. Children who previously would have perished from an array of childhood infections today live healthy and long lives thanks to sanitation improvements, vaccines, and antibiotics. In the United States, the average life expectancy at birth rose from less than 50 years in 1900 to more than 76 years in 1999, due in considerable measure to continuing reductions in infant and child mortality (NCHS, 2001c).

Antibiotics have had a massive effect on the death rate and there are big worries in the medical and public health professions over increasing levels of resistance in bacteria and the increase in death rate which will follow.

Getting back to Sushil's post, early agricultural man had a massive impact on the environment as the change from forest to agricultural land released a huge amount of CO2 into the atmosphere warming the climate to such an extent that it has warded off the next ice age and given us the stable climate that we have enjoyed until recently.
