Pregnancy is such a special time for the entire expecting family. It is a time of planning and preparing for the birth of a child. It is also important to begin considering the steps you can take to help keep yourself and your baby protected from vaccine-preventable diseases – now and throughout your child’s life.

Before Becoming Pregnant

If you are planning to become pregnant, there are things you can do before and between pregnancies to increase your chances of having a healthy baby such as taking folic acid every day; quitting smoking, alcohol and street drugs; and making sure you are up-to-date on all recommended vaccines. Learn more.

Vaccines During Pregnancy

Vaccines are a part of a healthy pregnancy. When you get vaccinated during pregnancy, you are not only protecting yourself against dangerous, potentially deadly diseases, you are also passing some protection (immunity) *directly* to your baby.

When a pregnant woman gets vaccinated, her body creates protective antibodies (immunity against diseases) and passes some of these antibodies to her baby that will last until her little one is ready to start getting their own vaccines.

Your OB-GYN or midwife can tell you which vaccines are right for you throughout your pregnancy, but the Centers for Disease Control and Prevention (CDC), the American College of Obstetricians and Gynecologists (ACOG), the American College of Nurse-Midwives (ACNM), the American Academy of Family Physicians  (AAFP); and the Association of Women’s Health, Obstetric and Neonatal Nurses (AWHONN) all strongly recommend the influenza (flu) and Tdap (whooping cough) vaccines for pregnant women. Take a look at the “Immunization for Pregnant Women: A Call to Action” from AAFP, ACOG, ACNM and AWHONN.

Flu VaccineThe flu can cause serious health problems for pregnant women and their babies. Learn how getting the flu vaccine during pregnancy is safe and keeps both you and your baby protected from flu and its serious complications.

Tdap VaccineWhooping cough (also known as pertussis) can cause serious illness in people of all ages, but it is particularly dangerous for young babies. This is why pregnant women are recommended to get a Tdap vaccine during the 3rd trimester of every pregnancy. Learn how getting the Tdap vaccine during pregnancy is safe and keeps you and your baby protected from whooping cough and its possibly serious complications, including hospitalization and death.

Read VYF’s article published in the December 2020 Vaccine Awareness campaign about the importance of vaccinations for pregnant women even – and especially – during the COVID-19 pandemic.

Preparing for Your New Baby

Pregnancy is also good time to start thinking about the vaccines your baby will need once they are born. Especially because your little one will need their first vaccine before leaving the hospital.

Commonly Asked Questions About Vaccines for Pregnant Women

Because there are not currently enough COVID-19 vaccine doses to go around at this time, the ACIP recommends that healthcare personnel and those working and living in long-term care facilities be offered the first available doses of vaccine.

Pregnant and breastfeeding women, who are a part of a group that is recommended to get a COVID-19 vaccine, may choose to be vaccinated. 

Things to Consider When Getting Deciding Whether to Get a COVID-19 Vaccine (Advice from CDC and the Advisory Committee on Immunization Practices)
  • Getting a COVID-19 vaccine is a personal choice for pregnant and breastfeeding women. While a conversation with a healthcare provider may be helpful, it is not required prior to vaccination. Key considerations pregnant and breastfeeding women can discuss with their healthcare provider include:
    • The likelihood of exposure to COVID-19
    • The risks of COVID-19 to them and potential risks to their fetuses/newborn baby
    • What is known about the vaccine: how well it works to develop protection in the body, known side effects of the vaccine, and lack of data during pregnancy and breastfeeding
  • Pregnant women are at higher risk of severe illness from COVID-19, including illness that results in ICU admission, placement of a ventilator, and death. Additionally, pregnant women with COVID-19 might be at increased risk of adverse pregnancy outcomes, such as preterm birth.
  • The mRNA COVID-19 vaccines (both Pfizer-BioNTech and Moderna COVID-19 vaccines are mRNA vaccines) are expected to have some side effects, especially after the second dose. Pregnant women who experience fever following vaccination may be counseled to take acetaminophen because fever has been associated with adverse pregnancy outcomes. Acetaminophen may be offered as an option for pregnant women experiencing other post-vaccination symptoms as well.
  • There are limited data about the safety of COVID-19 vaccines in people who are pregnant. Animal developmental and reproductive toxicity (DART) studies are ongoing and studies in people who are pregnant are planned. CDC and the Food and Drug Administration (FDA) have safety monitoring systems in place to capture information about vaccination during pregnancy and will closely monitor reports. While studies have not yet been done, based on how mRNA vaccines work, experts believe they are unlikely to pose a risk for people who are pregnant. mRNA vaccines do not contain the live virus that causes COVID-19 and therefore cannot give someone COVID-19. Additionally, mRNA vaccines do not interact with genetic material DNA because the mRNA does not enter the nucleus of the cell. Cells break apart the mRNA quickly. However, the potential risks of mRNA vaccines to the pregnant person and her fetus are unknown because these vaccines have not been studied in pregnant women.
  • Routine testing for pregnancy before COVID-19 vaccination is not recommended. Women who are trying to become pregnant do not need to avoid pregnancy after receiving an mRNA COVID-19 vaccine.
  • There are no data on the safety of COVID-19 vaccines in breastfeeding women or on the effects of mRNA vaccines on infants who are breastfed or on milk production/excretion. mRNA vaccines are not thought to be a risk to breastfeeding infants.
  • Pregnant and breastfeeding women who decide to get vaccinated should continue to follow the current guidelines to prevent the spread of COVID-19 after they are vaccinated:
    • Wear a mask over your nose and mouth
    • Stay at least six feet away from others (social distancing)
    • Avoid crowds
    • Wash your hands with soap and water for 20 seconds or using hand sanitizer with at least 60% alcohol
    • Follow CDC travel guidance
    • Follow quarantine guidance after being around someone sick with COVID-19

Yes. According to the CDC, based on what is known at this time, pregnant people are at an increased risk for severe illness from COVID-19 compared to non-pregnant people. Additionally, pregnant people with COVID-19 might be at increased risk for other adverse outcomes, such as preterm birth.

How Can Pregnant Women Protect Themselves and Their Babies from COVID-19?

If you are pregnant, it is important to know how to be as safe as possible in order to help protect yourself and your baby.

The CDC recommends that you (and people you live with) take the following steps:

  • Limit interactions with people who might have been exposed to or infected with COVID-19, including people within your household, as much as possible.
  • When going out or interacting with others outside your immediate household,
    • Wear a mask, especially when other social distancing measures are difficult to maintain. (Wearing a mask is not a substitute for other preventive actions like washing hands frequently and avoiding close contact with other people.)
    • Avoid others who are not wearing masks or ask others around you to wear a mask, if possible.
    • Stay at least 6 feet away from others outside your household (both indoors and outdoors).
    • Wash your hands with soap and water for at least 20 seconds. If soap and water are not available, use a hand sanitizer with at least 60% alcohol.
  • Avoid activities where taking protective measures and social distancing may be difficult.
  • Don’t skip your healthcare appointments.
  • Get recommended vaccines and a 30-day supply of your medicines.

Visit ACOG’s website for more information and advice for pregnant women related to COVID-19.

Even breastfed babies need to be protected with vaccines at the recommended ages.

While breast milk provides your baby with important protection from some infections, such as colds, ear infections and diarrhea, breast milk will not protect them against all diseases.

Your baby needs the long-term protection  that can only come from making sure they get all their vaccinations according to the CDC’s recommended immunization schedule, before they are exposed to dangerous infectious diseases.

Yes. The flu shot is safe, during any trimester, for both you and your  baby. The flu shot has been safely given to millions of pregnant women over many years. You can not get the flu from the flu vaccine.

Multiple studies have shown that women who have gotten flu shots during pregnancy have not had a higher risk for miscarriage. One of the largest and strongest studies was conducted in CDC’s Vaccine Safety Datalink (VSD) project. The study looked at three flu seasons to see if there was any increased risk for miscarriage among pregnant women who had received a flu vaccine during their pregnancy. The study found NO increased risk for miscarriage after flu vaccination during pregnancy

It is also safe for women to get the flu vaccine while breastfeeding. In fact, breastfeeding also helps to protect babies because breast milk passes your antibodies to your baby, and these antibodies help your baby fight off flu.

Following is a list of studies that show that the flu vaccine is safe during pregnancy. Click on the studies below to read the research.

The CDC, the American Academy of Family Physicians (AAFP), the American College of Nurse-Midwives (ACNM), the American College of Obstetricians and Gynecologists(ACOG), and Association of Women’s Health, Obstetric and Neonatal Nurses (AWHONN) all strongly recommend that pregnant women get a flu shot for the best protection – for them and their babies – against serious flu illness and flu-related complications.

Flu shots have been safely given to millions of pregnant women over many years.

The CDC monitors flu vaccine safety in pregnant women during each flu season using the Vaccine Adverse Event Reporting System (VAERS) – a U.S. system that monitors health concerns following vaccination. In addition, vaccine safety research is done through the Vaccine Safety Datalink (VSD). which is a collaboration between CDC and nine healthcare organizations.

Yes. Tdap vaccinations during pregnancy have been studied for both safety and effectiveness. Medical and public health experts agree that the benefits of Tdap vaccination during pregnancy outweighs any potential risks to moms and babies. See the research that has been done to make sure the Tdap vaccine during pregnancy is safe and effective for women and their babies.

The CDC, the American Academy of Family Physicians, the American College of Nurse-Midwives, the American College of Obstetricians and Gynecologists; and Association of Women’s Health, Obstetric and Neonatal Nurses all strongly recommend that women get a Tdap vaccination during the third trimester of every pregnancy to protect them and their babies against whooping cough.

No. The way that flu vaccines are made they cannot cause the flu. Flu shots are made from either flu viruses that have been ‘inactivated’ (killed) OR from proteins of a flu virus (instead of the full virus) so they can create an immune response without causing a flu infection.

While some people may get mild side effects from the flu shot like a sore arm, a headache, muscle aches or a low fever, those side effects usually begin soon after the shot and only last 1 -2 days.

Learn more about the current flu season.

Learn more about how vaccines work.

The most common side effects from flu shots are soreness, redness, tenderness or swelling where the shot was given.  Some people also report having a low fever, headache and muscle aches. If these reactions occur, they usually begin soon after getting the shot and last 1-2 days.

Besides side effects, there are several reasons why someone might get flu symptoms, even after they have been vaccinated against flu.

  • Some people can become ill from other respiratory viruses besides flu such as rhinoviruses, which are associated with the common cold, cause symptoms similar to flu, and also spread and cause illness during the flu season. The flu vaccine only protects you from the flu, not other illnesses.
  • It is possible to be exposed to influenza viruses, which cause the flu, shortly before getting vaccinated or during the two-week period after vaccination that it takes the body to develop immune protection. This may result in a person becoming ill with flu before protection from the vaccine takes effect.
  • Some people may experience flu like symptoms even after getting vaccinated because they were exposed to a flu virus that is very different from the viruses the vaccine is designed to protect against. The ability of a flu vaccine to protect a person depends largely on the “match” between the viruses selected to make the flu vaccine that season and those spreading and causing illness. There are many different flu viruses that spread and cause illness among people.
  • The flu vaccine can vary in how well it works season to season, and sometimes people who get vaccinated may still get sick. However, the flu vaccine still offers important benefits. It will:
    • Reduce the severity of your illness if you got vaccinated, but still get sick from flu.
    • Reduce the risk of children dying from flu.
    • Reduce the risk of flu-associated hospitalization for children and adults.
    • Help protect people around you, including those who are more vulnerable to serious flu illness due to age and/or certain chronic health conditions.
    • Help protect people with certain chronic conditions from serious health complications.
    • Help protect women during and after pregnancy.

Yes. Studies shown that getting the Tdap (whooping cough) vaccine while you are pregnant is very safe for you and your baby. Severe side effects are extremely rare. You cannot get whooping cough from the Tdap vaccine.

OB-GYNs, nurse midwives, family physicians and other medical experts, who specialize in caring for pregnant women, agree that the Tdap vaccine is both important and safe for women (and their babies) during their third trimester of every pregnancy.

Getting the vaccine during pregnancy will not put you at increased risk for any pregnancy complications, and will help your baby be born with some protection against whooping cough. This is especially important since babies don’t start their own whooping cough vaccination series (DTaP) until they are 2 months old.

To read some of the research on Tdap vaccination of women during pregnancy, click on the links to the studies below. Find more research on the CDC website.

Getting a Tdap shot during every pregnancy – as opposed to before or after – allows your body to pass on some protective antibodies against whooping cough (immunity) to your baby. This is especially important since babies don’t start their own whooping cough vaccination series (DTaP) until they are 2 months old.

Getting vaccinated with Tdap during pregnancy also protects you during delivery and will make you less likely to pass whooping cough to your newborn.

A study published in Pediatrics in May 2017 looked to see how effective the Tdap vaccine was at preventing whooping cough in babies whose mothers got the vaccine while pregnant or in the hospital after giving birth. The study found that getting Tdap between the 27th through 36th weeks of pregnancy is 85% more effective at preventing whooping cough in babies younger than 2 months old.

Additionally, authors of the study, Sources of Infant Pertussis Infection in the United States published in October 2015 in Pediatrics, state that vaccinating pregnant women with Tdap increases protection of their babies.

Yes. Pregnant women can safely get the Tdap vaccine even if they recently got a tetanus-containing vaccine (Td or Tdap).

It does not matter when you got your last tetanus shot (Tdap or Td vaccine), you still need the Tdap vaccine during the 3rd trimester of each pregnancy to protect yourself and your newborn from whooping cough.

The protection (antibodies) that you pass on to your baby before birth is very important and will give them some early protection against flu and whooping cough. This is important because 

However, these antibodies will only give your baby short-term protection. That’s why it is also very important for your baby to get vaccinated according to the CDC’s recommended childhood immunization schedule, so he can start building his own protection against these dangerous diseases.

You may have heard that vaccines contain all types of crazy ingredients that sound as though they don’t belong in a medical product. The truth is that a very small group of very vocal, but misinformed, individuals have made false claims regarding the safety of vaccines and their ingredients. In most instances these claims are just wrong. In other cases, the claims are from information taken out of context or are trying to purposely mislead people.

The main ingredients in vaccines are antigens, which are small amounts of the bacteria or virus against which the person is being vaccinated. Antigens are the parts of the vaccine that encourage your immune system to create antibodies to fight against future infections. To make sure that the vaccines cannot cause the disease you are trying to protect against, the antigens are altered or weakened. Learn more about how vaccines are made and how they work.

Like many of the foods we eat and beverages we drink, vaccines also contain a small amount of additional ingredients, and each has a specific, necessary function. These ingredients may be added to the vaccine to make it more effective, sterile and/or safe. These additional ingredients have been studied and are safe for humans in the amount used in vaccines.

In fact, the amount of these additional ingredients in vaccines is much less than children encounter in their environment, food and water. As the saying goes, “the dose makes the poison.” In other words, any chemical – even water or oxygen – can be toxic or even deadly in large enough quantities.

Sometimes a child may be sensitive to one of the components of a vaccine, and an allergic reaction may result. For this reason, you should discuss any allergies your child may have with their healthcare provider.
