The whooping cough vaccine, also known as Tdap, does not contain a live virus. Instead, it is manufactured using inactivated non-infectious bacterial products that generate a robust immune response. This means that the vaccine cannot give someone whooping cough and is safe for both pregnant women and their babies. Getting vaccinated during pregnancy helps protect both mother and baby and lowers the risk of whooping cough in babies younger than two months old by 78%.

What You'll Learn
The whooping cough vaccine is safe for pregnant women and unborn babies
In 2011, the Advisory Committee on Immunization Practices (ACIP) recommended that pregnant women receive the Tdap vaccine during the second half of pregnancy. Since then, many pregnant women have received the vaccine during pregnancy, and there is a growing body of literature demonstrating its safety and effectiveness in protecting newborns against whooping cough. The CDC and ACIP recommend that pregnant women receive the Tdap vaccine during each pregnancy, preferably between the 27th and 36th week of gestation.
Vaccination during pregnancy helps protect both the mother and the baby. After receiving the Tdap vaccine, a pregnant woman's body creates protective antibodies, which are passed to the baby before birth through the placenta. These antibodies provide short-term protection against whooping cough in the early life of the baby, reducing the risk of developing the disease by 78% in babies younger than 2 months old. Studies have shown that babies whose mothers received the Tdap vaccine during pregnancy are less likely to get whooping cough and experience less serious infections.
There is no evidence to suggest that the whooping cough vaccine is unsafe for pregnant women or their unborn babies. A large study of around 20,000 vaccinated people found no increased risk of adverse pregnancy outcomes such as stillbirth, low birth weight, or pre-eclampsia. The vaccine has been used routinely in pregnant women in the UK since 2012, and multiple safety systems monitor its use during pregnancy. The Medicines and Healthcare products Regulatory Agency (MHRA) in the UK has also studied the safety of the vaccine, finding no evidence of risks to pregnancy or babies.

Tdap vaccines do not contain live bacteria
The Tdap vaccine is manufactured using inactivated non-infectious bacterial products that trigger an immune response in the body. Specifically, the whooping cough component of the Tdap vaccine contains inactivated parts of the bacteria that cause whooping cough, which is Bordetella pertussis. This means that the vaccine cannot give someone whooping cough, as it does not contain any live bacteria that can cause the disease.
The Tdap vaccine is very safe for pregnant women and their babies. Getting vaccinated during pregnancy does not increase the risk for pregnancy complications and has been shown to be effective in protecting newborns against whooping cough. The CDC and other medical associations dedicated to the health of pregnant women and children support the recommendation of Tdap vaccination during pregnancy.
In addition to not containing live bacteria, the Tdap vaccine also does not contain thimerosal. Thimerosal is a preservative that has been used in some vaccines, but it is not present in the Tdap vaccines currently used in the United States. Overall, the Tdap vaccine is a safe and effective way to protect against whooping cough and other diseases, and it can be administered to individuals without the risk of infection from live bacteria.

Tdap vaccines are recommended during the second half of pregnancy
The Tdap vaccine contains tetanus, diphtheria, and acellular pertussis (whooping cough) antigens. It does not contain a live virus because it is manufactured using inactivated, non-infectious bacterial products. The vaccine is safe for pregnant women and their babies and does not increase the risk of pregnancy complications. It has been approved by the FDA for use during pregnancy, and multiple safety systems monitor its use in pregnancy.
Vaccination during the second half of pregnancy maximizes the transfer of protective antibodies to the fetus, optimizing newborn protection. These antibodies provide short-term protection against whooping cough and can help protect the baby from some of the serious complications of the disease. Vaccination during pregnancy lowers the risk of whooping cough in babies younger than two months old by 78%.
It is important to note that the Tdap vaccine may be safely administered at any time during pregnancy if needed, especially in the case of wound management or pertussis outbreaks. However, if the vaccine is administered earlier in pregnancy, it should not be repeated between 27 and 36 weeks of gestation.

Tdap vaccines do not contain thimerosal
The Tdap vaccine does not contain thimerosal. Thimerosal is a mercury-containing organic compound that has been widely used as a preservative in biological and drug products, including many vaccines, to prevent the growth of harmful microbes inadvertently introduced into the vaccine during use. The use of mercury-containing preservatives has been declining in recent years due to the development of new products formulated into single-dose presentations that do not require preservatives.
The Tdap vaccine is recommended for pregnant women to help protect both mother and baby from whooping cough. The vaccine creates protective antibodies in the mother's body, which are then passed on to the baby before birth, providing short-term protection against whooping cough in early life. This vaccine has been recommended by the CDC since 2012 and is approved by the FDA.
The use of thimerosal as a preservative in vaccines has also declined due to the reformulation and development of vaccines supplied in single-use presentations. All vaccines routinely recommended for children 6 years of age and younger in the U.S. are available in formulations that do not contain thimerosal. Vaccines that do not contain thimerosal as a preservative are also available for adolescents and adults.
Research has shown no association between thimerosal exposure and neuropsychological delays or autism. Studies have concluded that thimerosal in vaccines does not contribute to the development of autism, and autism rates have continued to increase even after thimerosal was removed from childhood vaccines.

Tdap vaccines are approved by the FDA
The whooping cough vaccine, also known as Tdap, does not contain a live virus or live bacteria. Instead, it is manufactured using inactivated, non-infectious bacterial products that generate a robust immune response.
Tdap Vaccines Approved by the FDA
The Tdap vaccine has been approved by the FDA for use in pregnant women to prevent infant pertussis. The FDA approved the use of the Boostrix vaccine in pregnant women in 2022, and the Adacel vaccine in 2023. Adacel is the only Tdap vaccine available in a syringe made without natural rubber latex, which can help reduce the risk for patients with a latex allergy. The FDA approved Adacel for repeat vaccination in 2019, making it the first and only Tdap vaccine in the U.S. approved for a repeat dose in people 10 through 64 years of age, eight years or more after the first vaccination.
The FDA has also approved other vaccines that protect against tetanus, diphtheria, and pertussis (whooping cough). These include Daptacel, approved in 2002 for children aged 6 weeks to 6 years; Infanrix, approved in 1997 for the same age group; and Kinrix, approved in 2008 for children aged 4 to 6 years, which also protects against polio. TDVax and Tenivac are generic vaccines approved in 1967 and 2003, respectively, for individuals aged 7 years and older, protecting against tetanus and diphtheria.
The CDC and FDA are committed to monitoring the safety of vaccines, and multiple safety systems are in place to ensure the safety of the Tdap vaccine during pregnancy.
