This extract is corroborative evidence of CLEAN MILK being the HUGE contributor to reduced measles mortality.

The timing of both the reduction in gastro-enteritis and measles is EXACTLY THE SAME.

The common cause was milk which had TWO IMPACTS:

1) Huge reduction in bacterial infections (e.g. diarrheal diseases) 

2) Massive increase in Vitamin A intake by children which improved their ability fight pneumonia bacteria (which do not transmit via milk but are found in the respiratory tract of ALMOST ALL PEOPLE, e.g. Streptococcus pneumoniae). In the normal course, these bacteria do nothing - but when the immune system is weakened (by measles), the same bacteria can kill.
