Pregnant women get both COVID and flu shots at once in new safety study
NCT ID NCT06503900
First seen Nov 01, 2025 · Last updated Jun 23, 2026 · Updated 36 times
Summary
This study looked at whether it is safe for pregnant women to receive the mRNA COVID-19 vaccine and the flu shot at the same time versus a few weeks apart. 98 pregnant women were randomly assigned to one of the two schedules. Researchers tracked side effects, pregnancy outcomes, and baby health through delivery and 90 days after birth. The goal was to see if giving both vaccines together causes more problems than spacing them out.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
mRNA COVID-19 vaccine and inactivated influenza vaccine
What this could lead to
If successful, this could show that getting both vaccines at the same time is as safe as getting them separately during pregnancy, simplifying vaccination schedules.
What could go wrong
This is a small, completed trial with only 98 participants, so results may not apply to all pregnant women. It focuses on safety, not long-term effectiveness.
As listed by the trial registrant
The condition terms exactly as the trial's registrant entered them.
