Scientific Claim

In rural Tanzania, infants born at home have a 17% higher risk of delayed or incomplete DTP3 vaccination compared to those born in health facilities, highlighting birth location as a critical determinant of immunization timeliness in rural areas.

Original Statement

“In rural Morogoro, infants born at home had 17% (95% CI: 8-27%) increased risk for delayed or no receipt of DTP3 vaccination.”

In both cities and rural areas of Tanzania, teenage moms are much more likely to have babies who miss or are late on their vaccines than moms in their mid-20s.

In both cities and rural areas of Tanzania, babies from the poorest families are more likely to be late or miss their vaccines than babies from the richest families.

In rural Tanzania, babies who are the fifth or later child in their family are more likely to be late on their vaccines than the first child.

In rural Tanzania, moms with no school are much more likely to have babies who miss vaccines — but in cities, whether a mom went to school doesn’t seem to affect vaccine timing.

90%

In rural Tanzania, babies born small are actually less likely to miss their vaccines than babies born at a normal weight — the opposite of what’s seen in most other poor countries.
