Why tdap postpartum

In addition, routine surveillance activities include reviews of hospital discharge databases and mortality records to identify unreported cases. Infants with pertussis that was not diagnosed or treated in California would have been misclassified as noncases. Misclassification bias for the exposure is unlikely to be present in our study owing to use of provider-reported Tdap vaccination data from CAIR; these data were also collected before the outcome of pertussis in the infant, so any exposure misclassification would be nondifferential.

Significant differences were observed between mother-infant pairs with prenatal versus postpartum Tdap. This is expected given that vaccination during pregnancy may be a marker for both access and quality of prenatal care.

Importantly, when placed in the multivariate model, these factors showed no association with risk of pertussis, except for prior births. Infants were 1. Finally, our cohort may not be representative of all pregnant women in California.

Vaccination at 27—36 weeks gestation was more protective than vaccination before or after this window. Efforts should be made by prenatal care providers to provide Tdap to pregnant women on site during routine prenatal visits at the earliest opportunity between 27 and 36 weeks gestation. We are indebted to the 61 local health jurisdictions for their ongoing pertussis surveillance and vaccination efforts.

Pregnancy dose Tdap and postpartum cocooning to prevent infant pertussis: a decision analysis. Pediatrics ; : e — Sources of infant pertussis infection in the United States.

Cocooning, in combination with maternal Tdap vaccination during pregnancy and administering the childhood DTaP series on schedule, provides the best protection to the infant. In addition to vaccinating your pregnant patients with Tdap, you should educate them about encouraging others who will have contact with the infant — including fathers, grandparents and other infant caregivers — to be up to date with pertussis vaccination.

Protection from pertussis vaccines is not long lasting, so CDC recommends Tdap during pregnancy in order to provide optimal protection i. If you administer Tdap at a preconception visit, you should administer it again during pregnancy between 27 through 36 weeks gestation. Pregnant women should receive Tdap anytime during pregnancy if it is indicated e. If you administer Tdap earlier in pregnancy, you do not need to repeat it between 27 through 36 weeks gestation; CDC recommends only one dose during each pregnancy.

Vaccinating Pregnant Patients. On average, about 1, infants are hospitalized and typically between five and 15 infants die each year in the United States due to pertussis. Most of these deaths are among infants who are too young to be protected by the childhood pertussis vaccine series that starts when infants are 2 months old.

These first few months of life are when infants are at the greatest risk of contracting pertussis and having severe, potentially life-threatening complications from the infection. To help protect babies during this time when they are most vulnerable, women should get the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine Tdap during each pregnancy.
