Women who are pregnant should get vaccinated with both the influenza and Tdap vaccines to protect themselves and their babies.
“Vaccination of pregnant women with influenza vaccine and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) can decrease the risk for influenza and pertussis among pregnant women and their infants.”

These are not new recommendations.
Influenza and Tdap Vaccination for Pregnant Women
Although some vaccines are contraindicated when you are pregnant, it has long been recommended that all pregnant women get:
- a flu vaccine – any trimester – a recommendation that has been evolving since 1983
- the Tdap vaccine during each and every pregnancy between 27 and 36 weeks of gestation – a recommendation that been evolving since 2011
Still, many pregnant women are still not getting vaccinated like they should, leaving themselves and their babies at risk for the flu and pertussis.
Influenza and Tdap Vaccination Rates Among Pregnant Women
While influenza and Tdap vaccination rates in pregnant women are rising, they are still suboptimal, as we can see in a new report from the CDC, Influenza and Tdap Vaccination Coverage Among Pregnant Women — United States, April 2020.
“Among 1,841 survey respondents who were pregnant anytime during October 2019–January 2020, 61.2% reported receiving influenza vaccine before or during their pregnancy, an increase of 7.5 percentage points compared with the rate during the 2018–19 season. Among 463 respondents who had a live birth by their survey date, 56.6% reported receiving Tdap during pregnancy, similar to the 2018–19 season.”

Just over half of pregnant moms are getting vaccinated.
And as we have seen in other recent surveys, guess who was most likely to get vaccinated and protected?
“Vaccination coverage was highest among women who reported receiving a provider offer or referral for vaccination (influenza = 75.2%; Tdap = 72.7%).”

Not surprisingly, more pregnant women were vaccinated if their providers simply offered flu and Tdap vaccines!
Why is all of this important?
Even though it is known that neither the flu nor Tdap vaccines provide perfect protection, it is well known that they provide very good protection to pregnant mothers and to newborns and younger infants who are too young to get their own vaccines.
“In 2012, the Centers for Disease Control and Prevention received more than 41 000 reports of pertussis infection in the United States (US), with 18 deaths. Most of those who died were unvaccinated infants younger than 3 months of age.”

Protection that can keep them from dying from pertussis.
“Infants born to women reporting influenza immunization during pregnancy had risk reductions of 64% for ILI, 70% for laboratory-confirmed influenza, and 81% for influenza hospitalizations in their first 6 months.”
Influenza in Infants Born to Women Vaccinated During Pregnancy
Protection that can keep them from dying from flu too.
“Pandemic influenza virus infection in pregnancy was associated with an increased risk of fetal death. Vaccination during pregnancy reduced the risk of an influenza diagnosis. Vaccination itself was not associated with increased fetal mortality and may have reduced the risk of influenza-related fetal death during the pandemic.”

So don’t skip your flu or Tdap vaccine, especially if you are pregnant.

These vaccines in pregnancy are safe, effective, and very necessary.
Did your health care provider recommend that you get a flu and Tdap vaccine when you were pregnant?

Do you now understand why you should?
