The Micronutrient Initiative has been in operation for about 20 years. UNICEF, when it announced its reduced child mortality rates in September 2009, stated that child mortality rates dropped from 12.5 million in 1990 to about 8.8 million now. The Lancet put out a further review saying that it was perhaps 7.2 million child deaths. UNICEF has credited vitamin A as one of the major reasons that child mortality has been reduced during the past 20 years.
