Many vaccines protect you and your baby while pregnant and breastfeeding

Pregnant people are at much higher risk for complications and death from influenza and COVID-19. Vaccination during pregnancy also helps to protect the newborn from many infections during the first few months after birth, like whooping cough.

After rigorous research, many vaccines are now strongly recommended for pregnant and breastfeeding people by the CDC, and tens of thousands of obstetricians, midwives, family physicians and other OB providers -- including the COVID-19, seasonal influenza, and the Tdap (whooping cough) vaccine.

When it comes to you and your baby's health, having accurate information is vital. This resource is updated with the latest research into vaccine safety, pregnancy and the whooping cough and COVID-19 vaccines. Find the answers to all your questions, curated by medical professionals, with links to verified research.

Frequently Asked Questions

General Information about RSV
What is RSV?

RSV, or respiratory syncytial virus, is a common respiratory virus that usually causes mild, cold-like symptoms in healthy adults. In infants and children, however, RSV can cause severe respiratory symptoms, and can even lead to hospitalization or death.

Each year in the United States, an estimated 58,000-80,000 children younger than 5 years are hospitalized due to RSV infection. In the U.S., RSV cases start in the fall and are highest around the middle of February.

How do I protect my baby from RSV?

There are two ways. You can choose to get the RSV vaccine (Abrysvo) during weeks 32 through 36 of your pregnancy during September to January, or your baby aged 8 months or younger can get the RSV monoclonal antibody (Beyfortus) during their first RSV season. The antibody has been used in premature infants since 1998 and was recently approved for all babies under 8 months as well.

Children between 8 and 19 months of age who are at higher risk due to medical conditions or weak immune systems can also get Beyfortus in their second RSV season.

Children between 8 and 19 months of age who are American Indian and Alaska Native are also recommended to get Beyfortus in their second RSV season since they are at more risk of getting severe RSV disease.

Beyfortus costs about twice the amount of Abrysvo, but health insurance companies are updating their coverage to include both. Some clinics and pharmacies may not carry both. Check with your insurance and physician or pharmacy to see what is covered and available for you.

Information about RSV Vaccine
Why should I get the RSV vaccine when I’m pregnant?

The RSV vaccine is recommended during the third trimester of pregnancy because it helps protect your newborn from the RSV virus, which can cause serious lung infections in newborns. When you are vaccinated for RSV during pregnancy, your body produces germ-fighting cells that cross the placenta and can help protect your newborn baby. This is similar to how the Tdap (Whooping cough) vaccine can protect your baby.

CDC - RSV Vaccination for Pregnant People

What are the recommendations for the RSV vaccine in pregnancy?

Pregnant people should be vaccinated between weeks 32 through 36 of pregnancy from September through January, which is the season when people tend to get sick with RSV. This way, your baby is protected against lung infections related to RSV in the first months of life. The vaccine can reduce a baby’s risk of being hospitalized from RSV by 57% in the first six months after birth.

CDC - RSV Vaccination for Pregnant People

When should I get vaccinated for RSV?

You are eligible to be vaccinated for RSV in pregnancy if you are between 32-36 weeks during RSV season, from September through January.  See the table below for a helpful timeline of when you can first get the vaccination based on your due date.

If you are due between April and October, it is recommended that your newborn receive the RSV vaccination within one week after birth.

Is the RSV vaccine safe for me and my baby?

Yes! The RSV vaccine has undergone safety studies in populations including pregnant individuals. Any vaccine can carry the risk of a temporary injection site reaction, like itching or pain. It is safe to breastfeed after getting the vaccine as well. It has not been shown to be excreted in breast milk.

I have heard that the RSV vaccine causes preterm labor. Is that true?

People at risk of preterm labor are not usually included in drug and vaccine trials, so it can be hard to assess this. Additional studies are underway to evaluate this risk, so the vaccine is currently approved in the late third trimester to reduce any potential safety concerns.

Source: 
Healthcare Providers: RSV Vaccination for Pregnant People

What about pre-eclampsia?

There is evidence that the RSV vaccine is associated with preeclampsia, and further studies are ongoing to evaluate this risk. However, RSV infection itself is also associated with preeclampsia, so it is important to protect pregnant people from RSV.

Should people in my family also get the RSV vaccine?

The RSV vaccine (Arexvy or Abrysvo) is recommended for adults over 60 years old based on a discussion with their primary care provider. Currently, there is no vaccine approved for non-pregnant adults under 60 years old.

Where can I get the RSV vaccine or the RSV monoclonal antibody?

Most clinics carry the RSV vaccine during the RSV season, and you can receive the vaccine at one of your routine visits.  If your provider does not carry the RSV vaccine, most local pharmacies can provide the vaccine. Check with your pharmacy to make sure they carry the Abrysvo vaccine. You can use this link to locate a clinic or pharmacy near you that offers the RSV vaccine.

If you do not get vaccinated against RSV during your pregnancy, your baby can receive the RSV monoclonal antibody in the hospital shortly after birth.

What is the RSV monoclonal antibody?

When we are exposed to a new germ, our bodies make proteins called “antibodies” that help us fight off viruses and bacteria. Beyfortus is an antibody product that protects your baby from RSV. The effect of Beyfortus is similar to getting a vaccine but it skips the step where the vaccine activates your body’s immune system to make the antibodies. Instead, Beyfortus provides the antibodies directly to your baby to prevent them from getting sick from RSV!

Source:
CDC - Respiratory Syncytial Virus (RSV) Preventive Antibody

What are the recommendations for the RSV monoclonal antibody (Beyfortus) for newborns?

If you elect not to receive the RSV vaccine, an alternative option to protect your newborn is to give them the RSV monoclonal antibody within 1 week of birth.

Source:
CDC - RSV Immunization for Infants and Young Children

What is better: the RSV vaccine during pregnancy or the RSV monoclonal antibody shortly after birth?

They are both effective! As of now, studies have not compared the two  options directly. However, both have been shown to provide protection against RSV to vulnerable infants. You should choose what works best for you and your family, taking into account whether you are eligible to receive the vaccination in pregnancy based on your due date.

General Information about Influenza
Expand to read FAQ answer
What is Influenza?

Influenza, which is commonly called the flu, is a highly contagious respiratory illness. The flu is transmitted through droplets from coughing and sneezing. You can catch the flu from contact with an infected person or by touching something that an infected person has coughed or sneezed on. Although the flu spreads year-round, it is most common during “flu season” which is from October through February.

Why do we worry about influenza during pregnancy?

During pregnancy there is a higher risk of the flu causing serious illness in both the mom and baby. In pregnancy, there is a greater chance that catching the flu might lead someone to become so sick that they need a breathing tube, become hospitalized or even die from the flu. Catching the flu during pregnancy can also increase the risk of preterm and stillbirth.

Why do we worry about influenza infections in newborns?

The flu can also cause serious disease in newborns, whose immune systems aren’t fully developed yet. Newborns younger than six months old have the highest risk of hospitalization and death from flu infections. 1 These babies are too young to be vaccinated against the flu themselves.

Why should I get the influenza vaccine when I'm pregnant?

The flu vaccine is the best protection against the flu for you and your baby. Studies have shown that getting the flu shot during pregnancy reduces the risk of being hospitalized for flu symptoms by about 40%.The vaccine during pregnancy also helps protect babies against the flu after they are born. Because newborns cannot get their own flu shots until they are 6 months old, they rely on flu-fighting antibodies they receive from their mothers being vaccinated to fight off illness.

Is the influenza vaccine safe for me and my baby?

Yes! The flu vaccine has undergone extensive safety studies showing that the vaccine is safe and effecting during any trimester of pregnancy. Multiple studies have shown that people who receive flu shots during pregnancy do not have an increased likelihood of miscarriage, adverse fetal outcomes, or other pregnancy complications.

Obstetrics & Gynecology - Inactivated Influenza Vaccine During Pregnancy

I got my flu vaccine last year, does that mean I am still protected against the flu this year?

The influenza virus changes from year to year which is why last year’s vaccine may not protect you from this year’s influenza virus. It is recommended that everyone 6 months and older receive the flu shot each year.

Does it matter if I get the flu shot versus the nasal spray?

Yes. Pregnant patients should receive the flu shot because it is made from inactive or “killed” virus, meaning it is no longer infectious. It is not possible for you or your growing baby to catch the flu from this flu shot. The nasal spray vaccine is made from live virus particles and is not recommended during pregnancy. That said, after you give birth, it is safe to receive either the flu shot or the nasal spray, even if you are breastfeeding.

What are the side effects of the flu vaccine? Are there any side effects in pregnancy?

The side effects from the flu vaccine are generally mild and resolve within a few days. Side effects include soreness and/or swelling where the shot was given, headache, fever, nausea, muscle aches, and fatigue.  Side effects are similar in pregnancy.

Where can I get the flu vaccine?

Most clinics carry the flu vaccine during flu season if not year-round, and you can receive the vaccine during one of your routine visits. You can also get the flu vaccine at your local pharmacy.

COVID-19 Vaccine Safety & Risks
Expand to read FAQ answer
How can I be sure the COVID-19 vaccine is safe for me and my baby?

Numerous studies including thousands of pregnant and breastfeeding individuals have shown that COVID-19 vaccinations are safe and effective. More than 100,000 pregnant individuals in the US have already received one of the COVID-19 vaccines.

We have included a Google Doc table that summarizes the findings on the safety of COVID-19 vaccination in pregnancy from more than 25 studies in different countries that include more than 315,000 pregnant women. Overall, there was no harmful effect of COVID-19 vaccination on  pregnancy outcomes found in any of these studies. Some studies found that women vaccinated for COVID-19 had a lower risk of preterm birth, stillbirth, a small baby, or having a newborn that required admission to a neonatal intensive care unit. This means that these studies found that COVID-19 vaccination supported healthier pregnancy outcomes. If you read this document, it uses abbreviations to describe the many pregnancy outcomes that were studied. Here is what some of these abbreviations mean. "PTB" means a preterm birth that occurs at least 3 weeks earlier than the expected due date. "NICU" stands for a neonatal intensive care unit. "SGA" means having a smaller baby than would be  expected based on the time (gestational age) in pregnancy when the baby was  delivered.

I have kept my family safe so far by masking, hand washing, and social distancing. Why is it still important to get vaccinated against COVID-19?  

Great question! Thousands of Americans have been unfortunately surprised when they acquired COVID-19 despite being very careful. It’s tough to control for every possible exposure especially when masking isn’t universal in all communities. The Delta variant of COVID-19 is highly infectious and two times as contagious as the original COVID-19 strain. It is as infectious as chicken pox. Given the risks in pregnancy of COVID-19 and the safety of the COVID-19 vaccines, it is highly recommended to become vaccinated in pregnancy or while breastfeeding. This is the best way to protect you and your family.

Are the side effects of the COVID-19 vaccine worse for pregnant women?

No. Commonly reported side effects across the different types of vaccines include fevers, fatigue, headaches, and body aches which is the same side effect profile for non-pregnant persons. Interestingly, a study of nearly 8,000 pregnant women found that there were fewer reports of side effects, like fever and muscle pain, compared to non-pregnant women.

Can the COVID-19 vaccine cause birth defects?

No. About 3-5% of babies in the United States are born with a birth defect each year. Among 1,612 women receiving the COVID-19 vaccine while pregnant, 45 had birth defects for a rate of 2.7%. This is what we would normally expect and does not indicate any relationship to the COVID-19 vaccine.

Can the COVID-19 vaccine cause a miscarriage or stillbirth?

No. Normal estimates of miscarriage in pregnancy range from 11% to 22%. In a study following 2,456 pregnant people who received the COVID-19 vaccine, a miscarriage occurred in 12.8%. This is what we would normally expect.

Can any of the COVID-19 vaccines change my DNA, implant a microchip or make my arm magnetic?

None of the COVID-19 vaccines change your DNA. They never go into the cell nucleus, which is the control center of the cell where your DNA lives.

None of the COVID-19 vaccines contain a microchip or can make your arm magnetic. These are myths.

Can I get the COVID-19 vaccine and another vaccine at the same time?

Yes. The immune system is very skilled at making protective antibodies to different vaccines or infections at the same time. Common prenatal vaccines like the influenza and the TdAP (tetanus/pertussis) are recommended in all pregnancies and can safely be paired with the COVID-19 vaccines.

How does COVID-19 vaccination protect my baby if I am breastfeeding?

Breast milk is so much more than nutrition and has long been known to protect infants against numerous infections by passing protective antibodies from the mother to the infant. Many studies have shown that breast milk from individuals vaccinated against flu while pregnant contains protective antibodies that can be passed to the infant. Recent studies have shown that protective antibodies against COVID-19 transfer in breast milk following COVID-19 vaccination.

I’m worried that pharmaceutical companies rushed the production of the vaccine for financial gain. Why should I trust them that the vaccine is safe?

The COVID-19 vaccine was developed quickly, but the clinical trials to examine the safety and efficacy were not rushed. Vaccine development and testing often takes years because there is a lot of bureaucratic and administrative hurdles that often take a long time. Due to the pressing public need, these administrative blocks were minimized without compromising the many months needed to conduct thorough testing. And while companies do make money off of vaccines, they are often the least profitable product in comparison to other drugs like Viagra.

We understand that it can be difficult to trust pharmaceutical companies, especially considering their role in the current opioid crisis. However, the vaccine still has no individual cost to you and is an important measure in protecting the health of you and your child, just like taking prenatal supplements and wellness checks.

There is so much conflicting information out there about vaccine safety. How can I tell what’s accurate?

There has been so much conflicting information online, especially in the media. We recommend following traditional misinformation debunking techniques:

1. First, identify the source of the information you are seeing. Is it a reputable source? Is the source from a well-established, scientifically credible organization such as the CDC, American College of Obstetrics & Gynecology or the, Society for Maternal and Fetal Medicine etc. If the source is an individual, what are their credentials? If it's difficult to assess, always feel free to ask your OB provider.  They are on your care team and happy to help you find accurate and trusted information about the COVID-19 vaccine.

2. Find coverage on the topic from multiple sources. What do multiple experts, outlets, and organizations say about the topic?
On this page, we have referenced all of our answers with scientific studies and recommendations from highly credible medical societies. Thousands of pregnant and breastfeeding individuals have contributed to these studies.

My community has been subject to racism in the health care system. How can I trust the medical establishment's recommendation to get the COVID-19 vaccine in light of historically unethical practices such as experimentation on Black, Latinx, Indigenous and Asian American communities in the US?

Racism in medicine is a grave injustice and failure to support the health of the communities we are meant to serve. We recognize your very valid concerns about the COVID-19 vaccine given your lived experiences with racism with the medical establishment and healthcare providers. We are worried about the disproportionately high rates of COVID-19, associated suffering and death amongst communities of color. We hope that by increasing vaccination rates, especially amongst pregnant individuals, this will protect the health of you and your babies. We hope that you will connect with trusted family members, community leaders and healthcare providers to learn more about their experiences with the COVID-19 vaccine. We highly recommend getting vaccinated against COVID-19 in pregnancy to protect the health of yourself and your baby.

Risks of COVID-19 Disease While Pregnant
Expand to read FAQ answer
Can the virus that causes COVID-19 be transferred from mother to baby in pregnancy?

Yes. In a study of 3,750 infants born to pregnant individuals with COVID-19, 8.1% of newborns tested positive for COVID-19.

What are my risks of COVID-19 in pregnancy or soon after delivery?

Pregnant or recently pregnant individuals acquiring COVID-19 have a much higher risks of dying, being hospitalized, needing a breathing tube, and having a preterm birth or stillbirth. In a short time, 15 pregnant women died of COVID-19 in Mississippi alone and 8 of those deaths occurred in a few months during a Delta variant peak in 2021. Being overweight at the start of a pregnancy or having diabetes further increases these risks. Overall, pregnant individuals with COVID-19 are 22 times more likely to die in pregnancy compared to uninfected pregnant people.

When pregnant individuals become ill with COVID-19 and need a ventilator, one way to improve their breathing is by delivering the baby. This means that delivering a baby prematurely (weeks or months too early) could help the pregnant person survive, but at the expense of the baby’s health. One study found that unvaccinated pregnant individuals with COVID-19 had a 59% higher rate of preterm birth compared to those without COVID-19. Preterm birth is harmful for your baby and can lead to serious complications including developmental and physical disabilities, long NICU stays, and even fetal death.

What are the current recommendations regarding the Johnson & Johnson vaccine?

As of May 6, 2022, the Washington Department of Health paused the use of the Janssen COVID-19 Vaccine (Johnson & Johnson)  for people 18 years and older. The update followed guidance and recommendations from the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) and the Western States Scientific Safety Review Workgroup.

The update followed data presented to the ACIP about thrombosis and thrombocytopenia syndrome, or TTS. TTS is a rare but serious condition involving blood clots and a low blood platelet count seen in some people who received the J&J vaccine. Though TTS was rare, the FDA showed the risk of certain side effects warranted limiting the vaccine. Nationwide, 54 cases of TTS, including nine confirmed deaths, were reported, which is a fraction of a percent of the 14 million doses of J&J given overall. While TTS was been seen in both men and women, the most at-risk group was women 30 through 49 years old.

The Pfizer-BioNTech and Moderna COVID-19 vaccines, both of which are mRNA vaccines and use a different method than the J&J COVID-19 vaccine to protect against the virus, have not been linked to blood clots at this time.

How Do the COVID-19 Vaccines Work?
Expand to read FAQ answer
How do COVID-19 mRNA vaccines (Pfizer and Moderna) work?

All of the COVID-19 vaccines “train” the immune system to identify, attack and destroy a tiny piece of the virus. This is how your immune system “learns the enemy” and can then quickly respond and bring in waves of immune cells to defeat the real virus in the future.

The Pfizer and Moderna vaccines work by introducing messenger RNA (mRNA) into muscle cells. The cells make lots of copies of the COVID-19 spike protein, which triggers the body to make a protective immune response. The mRNA is quickly degraded, because the cell breaks it up into small harmless pieces after a few days. mRNA is very fragile, which is one reason the Pfizer vaccine needs to be kept in very cold freezers. There is no “live virus” in the COVID-19 vaccine or any other harmful ingredients, thus making the COVID-19 vaccine safe for pregnant and breastfeeding individuals.

COVID-19 Vaccines and Your Menstrual Period and Fertility
Expand to read FAQ answer
Is there a link between the COVID-19 vaccine and changes in periods?

This is being studied, but appears to be rare.  Period changes might occur in far less than 1% of individuals and are short-lived. In the United Kingdom, out of more than 49.1 million women who have been vaccinated there were 41,332 reports of possible menstrual cycle changes (0.0008%). 
A normal period can vary widely from person to person and month to month. Exercise, diet and even stress can change a period, as well as lots of medications including birth control. Several studies in different countries indicate that the psychological stress of the pandemic has increased the irregularity of women’s periods. In a study of 127 women with the COVID-19 disease, 16% noticed changes in their menstrual cycle, which most commonly was reported as an irregular period. Interestingly, women reporting more COVID-19 symptoms were more likely to have an abnormal period. In summary, it appears that irregular periods are commonly reported after COVID-19 disease (16%), especially when women are ill, and rare after COVID-19 vaccination (<1%). More research is still being done on this topic.

Can COVID-19 disease harm male fertility or his sex life?  

Yes. There are many studies now supporting that COVID-19 disease can temporarily harm a man’s fertility or permanently harm a man’s ability to have an erection. After reviewing research databases, the American Society for Reproductive Medicine said, "No evidence of any connection between COVID-19 vaccines and male infertility was found, but there were 50 reviews, 17 commentaries/letters to editors and nine original articles on how COVID-19 disease could possibly impact male fertility." We have listed some of the ways that COVID-19 disease can do this below:

1. Temporary decrease in sperm count and quality: A severe illness (of any kind) is known to lower sperm counts in men for 3-6 months, as having a fever during a severe illness disrupts the process of making sperm. Therefore, it is not surprising that men who have had COVID-19 disease have been reported to have lowered sperm count and quality. In general, changes in sperm count due to an infection are typically short-term and recover after 3 months of time. Longer term studies of sperm count and quality in men recovering from COVID-19 are needed.

2. Testicle swelling and pain. Several studies indicate that about 10-22% of men with COVID-19 disease will experience swelling of the testicles and pain, possibly due to a direct infection of the testes.

3. Erectile dysfunction. COVID-19 is known to injure blood vessels in many organs including the lungs, heart and brain leading to higher rates of heart attack and stroke. A penile erection depends on strong blood flow into the penis and healthy veins as well as, testosterone. There are many reports and studies of men losing their ability to have an erection after COVID-19 disease, which may be due to blood vessel damage, lower testosterone and/or psychological distress. How frequently this might occur is unknown.

Is there a link between COVID-19 vaccination and infertility?  

No. Thousands of women have become pregnant after receiving one or more COVID-19 vaccines. More than 4,800 people had a positive pregnancy test after receiving a first dose of either the Pfizer or Moderna COVID-19 vaccine. Another report documents more than 1,000 people becoming pregnant after receiving any COVID-19 vaccine. Medical societies that serve women who would like to become pregnant have overwhelmingly recommended that people thinking about becoming pregnant get the vaccine. Studies that included patients undergoing fertility treatments who also received the COVID-19 vaccine found that there were no problems with implantation or early pregnancy development.

In addition, there is no link to male infertility after receiving the COVID-19 vaccine. In fact, sperm count and quality has been studied in men before and after COVID-19 vaccination. Not only were there no harmful effects found, but sperm counts were also actually higher after vaccination. This was within normal individual variation and not thought to be due to the vaccination.

Variants, Boosters, and Prior COVID-19 Infection

I had COVID-19.  Do I still need the vaccine?

Yes. Compared to natural infection, the vaccine triggers the body to make powerful protective antibodies, which are successfully transferred to fetuses during pregnancy. Many people have become sick with COVID-19 more than once, which is likely the case due to the weaker immune response that comes from natural infections.

What if I am vaccinated and get a breakthrough COVID-19 infection in pregnancy?

Your disease is likely to be very mild and in some cases, people have no symptoms at all with a breakthrough infection. This means that your vaccine worked – it prevented a severe disease that could have killed you or caused a bad outcome in pregnancy. In studies of pregnant people hospitalized with COVID-19, 97% were unvaccinated.

Am I eligible for and should I get a COVID-19 booster?

Yes. The COVID-19 booster shot is recommended in pregnancy. If you are 5 months out from your second dose of the Pfizer or Moderna COVID-19 vaccines and are pregnant, you are due for your booster shot. You can receive your COVID-19 booster at any stage in pregnancy. This will help give your immune system an extra memory booster to continue protecting you and your baby against exposure to COVID-19.  Receiving a COVID-19 booster vaccine when you are eligible is extremely important in protecting you and your baby from severe disease.

Which COVID-19 booster should I get?

The CDC is recommending that an individual should get any of the current COVID-19 vaccine boosters that are currently available.  The timing of boosters and which booster to obtain continues to change and evolve.  Please check the latest information on boosters from the CDC.

What do we know about the new COVID-19 virus variants and pregnancy outcomes?

Every few months it seems that we are confronted with a new COVID-19 virus variant.  In the case of the Delta variant, pregnant people acquiring this COVID-19 variant were reported to have a 2-4 times higher risk of severe disease, preterm birth and needing to be placed on a ventilator.  Whether new COVID-19 variants will cause more or less infections and severe disease in pregnancy will take time to figure out.  As pregnant individuals are one of the highest risk groups for severe COVID-19 disease and death, it is extremely important to get vaccinated, receive a COVID-19 vaccine booster when eligible, stay careful with masking, social distancing and keeping your “bubble” small.

Tdap (Whooping Cough) Vaccine Safety & Risks
Expand to read FAQ answer
What is the Tdap vaccine?

Tdap stands for tetanus, diphtheria, and acellular pertussis. The Tdap vaccine helps protect you and your baby from three diseases: diphtheria, tetanus and pertussis. You may have also heard of the Tdap vaccine referred to as the “whooping cough” vaccine. “Whopping cough” is another name for pertussis.

Why should I get the Tdap vaccine when I’m pregnant?

The Tdap (whooping cough) vaccine is recommended during the third trimester of pregnancy because it helps protect your newborn from whooping cough (pertussis). Babies are not able to get the whooping cough vaccine until they are two months old, so they are vulnerable to whooping cough infection in the first few months of life. When a pregnant individual is vaccinated for whooping cough during pregnancy, their body produces germ fighting cells that cross the placenta and can help protect their newborn baby until they can be vaccinated.

What is whooping cough (pertussis)?

Whooping cough, or pertussis, is an infection that causes severe coughing and sometimes difficulty breathing. It can affect anyone, but the infection is most serious in newborn babies, and can even cause death. Unfortunately, the CDC reports that about 30% of babies in the U.S. <1 year-old who get whooping cough are hospitalized and 1 in 100 who need treatment in the hospital die. Newborns whose mothers did not receive the Tdap vaccine in pregnancy are at greater risk of severe illness.

What are the recommendations for the Tdap vaccine in pregnancy?

The most reputable society of doctors caring for pregnant women, the American College of Obstetrics and Gynecology, recommends that pregnant individuals get the Tdap/whooping cough vaccine between 27 and 36-weeks of pregnancy. Vaccinating during this time allows the pregnant person’s body to make cells that detect and fight off germs and transfer those cells to the baby.  Pregnant individuals should receive the Tdap vaccine during every pregnancy.

Is the Tdap vaccine safe for me and my baby?

Yes! Studies have shown that there is no increased risk to you or your baby after receiving the Tdap vaccine during pregnancy.

Should people in my family also get the Tdap vaccine?

Most adults will have received the Tdap vaccine at some point during adolescence. If an adult in close contact with your baby has never received a Tdap vaccine, the American College of Obstetricians and Gynecologists recommends the adult receive a Tdap vaccine 2 weeks before visiting your baby.

Where can I get the Tdap vaccine?

Most clinics carry the Tdap vaccine and you can receive the vaccine at one of your routine visits. If your provider does not carry the Tdap vaccine, most local pharmacies can provide the vaccine.
