Pregnancy is an important period when protecting the health of both the mother and baby is a priority. In addition to a healthy diet and regular check-ups, vaccinations can be effective in preventing infections and their complications.
Vaccines recommended during pregnancy are usually selected based on their safety and the protection they can give to a mother and a developing baby. But vaccination schedules can vary based on a woman’s health condition, location, previous vaccination history, and stage of pregnancy.
Why Are Vaccinations Important During Pregnancy?
Changes in the immune system during pregnancy can affect how the body treats certain infections. Some diseases become more severe during pregnancy and can also affect the baby.

Vaccination can help the mother’s immune system produce antibodies against specific infections. Some of these antibodies can cross the placenta and provide protection to the baby during the first months after birth when newborns may be too young for certain vaccines.
For this reason, vaccination is considered an important part of prenatal healthcare.
Vaccines Commonly Recommended During Pregnancy
The influenza vaccine is often recommended during pregnancy. Influenza can lead to more serious health complications in pregnant women, so vaccination can reduce the risk of complications. The seasonal flu vaccine is generally given during any trimester when recommended.

The Tdap vaccine, which protects against tetanus, diphtheria, and pertussis, is another very important pregnancy vaccine. It is often recommended in the later part of pregnancy to help newborns fight against whooping cough in their early weeks of life.
Depending on local recommendations and specific circumstances, other vaccines may be recommended during pregnancy. COVID-19 vaccination may be recommended according to current public-health guidance.
Vaccines Usually Avoided During Pregnancy
Not every vaccine is suitable during pregnancy. **Live vaccines** are generally avoided because of theoretical risks to the developing fetus.
Examples include vaccines against measles, mumps, and rubella (MMR) and chickenpox. If these vaccines are needed, they are usually considered before pregnancy or after delivery.
This does not mean women should skip necessary vaccinations altogether. Vaccination should be planned with a healthcare professional who can objectively assess the person’s situation.
What If You Missed a Vaccine Before Pregnancy?
If a woman finds out she is pregnant after receiving a vaccine that is generally avoided during pregnancy, she should inform her healthcare provider. Receiving such a vaccine accidentally does not mean that something will go wrong, but medical advice is required.
Women who are planning to get pregnant can also have a conversation with a doctor about their vaccination history. This can help identify vaccines that should ideally be completed before conception.
Talk to Your Doctor Before Getting Vaccinated
Vaccination during pregnancy should be based on professional medical advice. Your doctor must consider your trimester, medical history, previous vaccinations, travel plans, and exposure risks before recommending a vaccine.
The key message is simple: **the right vaccinations can help protect both mother and baby from potentially serious infections.** Pregnant women should keep their vaccination records updated and discuss recommended vaccines with their obstetrician or healthcare provider.
