In urban Tanzania, moms who start prenatal care late (third trimester) are more likely to have babies who miss their first DTP shot on time compared to moms who start in the second trimester.

Scientific Claim

In urban Dar es Salaam, mothers who attended their first antenatal care visit in the third trimester are associated with a 55% higher risk of delayed or incomplete DTP1 vaccination compared to those with second trimester booking.

Original Statement

“In Dar es Salaam, mothers who attended their first antenatal care (ANC) visit in the 3rd trimester had 1.55 (95% CI: 1.36-1.78) times the risk of delayed or not received vaccination as compared to those with a 2nd trimester booking.”

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.
