Pregnancy and Vaccines: What You Need to Know

When you're pregnant, your health is your baby's health too. Some vaccines can help protect both you and your baby from serious illnesses, but deciding to get vaccinated is entirely your choice. Here’s what you should know to make the best decision for you and your family.

Why Vaccines Matter During Pregnancy

Certain vaccines are safe and helpful for women before, during, and after pregnancy. They protect you from illnesses that could harm you or your baby. Even better, some vaccines provide antibodies that cross the placenta, giving your baby a head start in fighting off infections after birth.

Vaccines You Might Need While Pregnant

The vaccines recommended during pregnancy vary depending on your health, age, lifestyle, and travel plans. It’s always a good idea to check with your healthcare provider—they’ll guide you based on your unique situation. Here are two vaccines often recommended:

Flu Vaccine

When to get it: If you’re pregnant during flu season (fall and winter), getting vaccinated by the end of October is ideal. But even later in the season, it can still help.
Why it’s helpful: The flu vaccine is safe for pregnant women and has been used for years. It helps protect you and your baby for months after birth from flu-related complications.

Tdap Vaccine

When to get it: Between 27 and 36 weeks of pregnancy, but it’s safe anytime during pregnancy.
Why it’s helpful: Tdap protects against whooping cough, which can be dangerous for newborns. Even if you’ve had this vaccine before, it’s recommended for each pregnancy.

Vaccines to Avoid During Pregnancy

Some vaccines, especially live ones, are generally not recommended during pregnancy because of potential risks to the baby. These include:

HPV vaccine
Measles, mumps, rubella (MMR) vaccine
Nasal spray flu vaccine
Varicella (chickenpox) vaccine
Certain travel vaccines (e.g., yellow fever) unless absolutely necessary.

If you’ve already received one of these vaccines and then learn you’re pregnant, don’t panic. Talk to your healthcare provider—they’ll help you figure out what to do next.

What About After Birth?

After your baby is born, most vaccines are safe to get—even if you’re breastfeeding. Vaccines can help protect you and your baby as you recover and adjust to life as a new mom. However, a few (like the yellow fever vaccine) might not be recommended while breastfeeding unless absolutely necessary.

Final Thoughts

Your healthcare provider is your best resource for making decisions about vaccines during pregnancy. They’ll consider your medical history and help you decide what’s right for you. Remember, staying informed and asking questions is always a good idea.
