Quantifying maternal vaccination opportunities across gestational age windows: a real-world multi-country, longitudinal study.

Background

Maternal vaccination is a recognized strategy for reducing maternal and neonatal morbidity and mortality, including in low- and middle-income countries (LMICs).
