# Invasive Pneumococcal Disease among Childbearing-Age Women, United States, 2007–2023

## TL;DR

This study examines how often invasive pneumococcal disease occurs in pregnant and postpartum women in the US compared to nonpregnant women.

## Contribution

The study provides new population-based incidence estimates for pneumococcal disease in pregnant and postpartum women.

## Key findings

- Pregnant women had similar pneumococcal disease rates as nonpregnant women of childbearing age.
- Postpartum women had 3.5 times higher disease incidence compared to nonpregnant women.
- Findings may help guide pneumococcal vaccination recommendations for these groups.

## Abstract

US data on invasive pneumococcal disease incidence among pregnant and postpartum women are limited. We estimated incidence in those groups using population-based surveillance. Compared with nonpregnant women of childbearing age, incidence was similar for pregnant women but 3.5 times higher for postpartum women. Our findings could inform pneumococcal vaccine recommendations.
