What should you know about tetanus vaccine in pregnancy?

Tetanus is an infection caused when bacteria enter damaged tissue and release a toxin affecting muscles and nerves. Pregnancy vaccination advice varies with previous doses, local antenatal recommendations, the vaccine product, and whether an injury has occurred. The purpose of a clinical review is to choose an appropriate plan and explain how it supports maternal protection and, where relevant, protection around birth. An uncertain record does not mean you should guess or repeat doses without advice.

Tell your maternity team that you are pregnant and ask them to review your tetanus history. Share records of vaccines and any significant reactions, and mention allergies or medicines. For a cut or puncture, rinse with clean running water and soap, remove visible dirt gently, and arrange advice if the wound is deep, dirty, bitten, burned, crushed, or difficult to clean. Never use a veterinary vaccine for human protection.

Seek prompt assessment for a significant wound, particularly when cleaning is incomplete or contamination is possible. Urgent symptoms include difficulty opening the mouth, swallowing or breathing, severe stiffness, or muscle spasms. Increasing redness, heat, swelling, discharge, fever, or worsening pain also warrants medical review because pregnancy can make timely assessment especially important.

Ask which product and timing fit your pregnancy, how earlier doses change the plan, and whether a recent wound needs separate treatment. Ask which expected injection reactions can be observed at home and which symptoms should prompt a call.
