Tdap vaccine for pregnant women

Most hospitals (64 %) had no information about Tdap vaccination to prevent whooping cough in babies, and the few that did typically buried the information in archived documents.
The Centers for Disease Control and Prevention recommends Tdap vaccination of pregnant women between the 27th and 36th week of each pregnancy, to ensure that antibodies are transferred from mom to infant. The authors note that the birth of a child may especially be a prime time when parents and family members are on websites seeking information about preparing for the labor and delivery stay, hospital visiting hours or other policies.

So this Tdap study is bias from inception, just another stamp of approval on a dangerous drug they want to push to continue to give the illusion that drugs are needed to protect pregnant woman from the bogey man. A recent study has found that receiving the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine in the third trimester did not increase the risk of adverse events for the mother or infant. For the study, researchers randomly assigned 48 women to receive the Tdap vaccine (n = 33) or placebo (n = 15) at 30 to 32 weeks’ gestation to evaluate the safety and immunogenicity (ability to produce an immune response) of the vaccine administered during pregnancy.
The researchers found that injection site and systemic reactogenicity (adverse reactions) rates in pregnant women were not significantly different than those observed among postpartum or nonpregnant women. Also, concentrations of vaccine-induced pertussis antibodies in infants born to mothers immunized with Tdap during pregnancy were significantly higher at birth and at age 2 months than in infants whose mothers were immunized postpartum.


According to the report, pertussis is a highly contagious and potentially fatal vaccine-preventable disease that has re-emerged in the United States, despite high childhood immunization rates. Infants too young to receive the primary diphtheria and tetanus toxoids and acellular pertussis (DTaP) immunization series (recommended at 2, 4, and 6 months of age) depend on maternal antibodies for protection against the disease. Pregnant women who got inoculated with the Tdap (tetanus, diphtheria, acellular pertussis) vaccine did not have an increased risk of giving birth prematurely, a new study reported. The researchers found that the vaccine was not linked to an increased risk of preterm delivery or an increased risk of small-for-gestational-age births. The team noted that vaccinated women had a higher prevalence of chorioamnionities at 6.1 percent. The Advisory Committee on Immunization Practices recommends the Tdap vaccine for all pregnant women, especially during weeks 27 through 36 of gestation. Vaccination of family members further protects infants during the time they are too young to receive their own Tdap vaccinations.

Women who received placebo during pregnancy were given Tdap vaccine postpartum prior to hospital discharge, and women who received Tdap during pregnancy were given placebo postpartum.


Infants younger than 6 months are at greatest risk of disease, hospitalization, and death and account for more than 90% of all pertussis-associated deaths in the United States.
However, pregnant women have very low concentrations of pertussis antibodies to transfer to their newborn at the time of delivery; maternal immunization with the Tdap vaccine could help prevent infant pertussis, the study finds. The researchers added that the Tdap vaccine was also not linked to a greater risk of giving birth to a small-for-gestational-age infant. The Tdap shot is a combination vaccine that protects against serious bacteria-causing diseases diphtheria, tetanus, and whooping cough (pertussis). The vaccine, however, was tied to a slightly higher risk of being diagnosed with chorioamnionitis, which is a condition characterized by inflammation of the membranes that surround the fetus.
