Tetanus Injection in Pregnancy: When and Why It’s Given

During pregnancy, doctors recommend a number of tests and vaccinations to keep both mother and baby safe. One of the most common is the tetanus toxoid (TT) injection. 

Why Is Tetanus Injection Important in Pregnancy?

Tetanus is a serious infection caused by bacteria that enter the body through wounds or cuts. During childbirth — especially in environments where delivery instruments or the cord-cutting process may not be fully sterile — both mother and baby are at risk.

The tetanus injection:

• Protects the mother from infection during delivery.
• Protects the newborn from neonatal tetanus, which can be life-threatening.

When Is the Tetanus Injection Given?

The timing can vary depending on whether you’ve had a tetanus shot in the past few years. Generally:

• First dose (TT1): Around 16–24 weeks of pregnancy (second trimester).
• Second dose (TT2): At least 4 weeks after the first dose, ideally before the 36th week.

If you’ve been fully vaccinated in the past 5 years, sometimes only a single booster dose may be advised. Your doctor will guide you based on your vaccination history.

How Many Tetanus Shots Are Needed?

• Two doses are usually recommended during a first pregnancy.
• In subsequent pregnancies, if the previous two-dose course was completed within the last 3 years, only one booster dose may be required.
• The goal is to ensure protection for both mother and baby at the time of delivery.

Are There Any Side Effects?

The TT injection is considered very safe in pregnancy. Mild pain or swelling at the injection site is common, but serious side effects are extremely rare.

Final Word

The tetanus injection is a small but powerful step in ensuring a safe pregnancy and healthy delivery. Always check with your OB-GYN about your vaccination schedule, and make sure you complete the recommended doses on time.
