Observational, Passive Surveillance Program to Collect Information on Women and Their Offspring Exposed to MenQuadfi® During Pregnancy, in United States (US)

November 27, 2025 updated by: Sanofi Pasteur, a Sanofi Company

The MenQuadfi® Pregnancy Registry: A Surveillance Registry to Assess the Safety of MenQuadfi® Among Exposed Pregnant Women and Their Offspring

Primary Objective:

To assess maternal, obstetrical, pregnancy, and neonatal and infant outcomes among women vaccinated with MenQuadfi® during pregnancy or in the 30 days preceding their Last Menstrual Period (LMP).

Study Overview

Detailed Description

This study is a prospective pregnancy registry to collect and analyze the outcome of exposure to MenQuadfi™ during pregnancy or within 30 days prior to their LMP. The registry will encourage prospective registration, which is defined as registration of a pregnancy exposure prior to knowledge or perceived knowledge of the pregnancy outcome.

Exposed pregnant women will be followed up to the end of their pregnancy, and the offspring(s) will be followed up to 1 year of age.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of pregnant women with maternal adverse events (AEs)
Time Frame: From vaccination to end of follow-up (i.e.,up to 22 months after cohort entry)
Maternal adverse events defined as any reported adverse event (AE), following vaccination of a pregnant woman, occurring independent of the pregnancy (e.g., injection site reactions)
From vaccination to end of follow-up (i.e.,up to 22 months after cohort entry)
Percentage of pregnant women with obstetrical AEs
Time Frame: From vaccination to 28 days after delivery
Obstetrical adverse events defined as any reported AE, following vaccination of a pregnant woman, related directly to the pregnancy (e.g., complications of pregnancy, labor and delivery, and puerperium)
From vaccination to 28 days after delivery
Percentage of pregnant women with pregnancy AEs
Time Frame: On day of birth
Pregnancy adverse events defined as any reported AE, following vaccination of a pregnant woman, related to birth outcomes (e.g., live birth, spontaneous abortion/miscarriage, stillbirth/fetal death)
On day of birth

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of offsprings with adverse neonatal AEs
Time Frame: From day of birth to 28 days post-birth
Neonatal events defined as any reported AE, following vaccination of a pregnant woman, directly related to the infant and assessed immediately after birth or within the first 28 days of life (e.g., congenital anomalies)
From day of birth to 28 days post-birth
Percentage of offsprings with adverse infant AEs
Time Frame: From day 29 post-birth to 365 days post-birth
Infant events defined as any reported AE, following vaccination of a pregnant woman, directly related to the infant occurring / diagnosed between days 29 and 365 post-birth
From day 29 post-birth to 365 days post-birth
