According to the report, about 130 million children are born each year, and since 1990, about 70-ercent have received the vital immunizations - up from some 20-percent under the age of 1 in 1980.
Since then, however, efforts to reach the remaining 20 or 30-percent who need help - mainly in poor countries - are lacking.
Dr. Peter Salama, UNICEF's chief of immunizations, says about $1 billion is now being spent on childhood immunization and about $1 billion more is needed to reach a goal set in 2002 of bringing vaccines to at least 90-percent of children worldwide under the age of one by 2010.
A UNICEF report focuses on the divide between vaccinations in rich and poor nations. In 2003, 90-percent of children in industrialized nations had proper immunizations. Those in west and central Africa, however, are at just 52-percent.
Overall, the report states 103 countries have a 90-percent protection rate against measles, while 16 are likely to achieve that rate by 2010. Another 55 need improvements, while 16 must reverse declining immunization rates.
