Pregnant, when to vaccinate against whooping cough?

The High Health Authority recommends that pregnant women should be vaccinated against whooping cough from the second trimester of pregnancy, preferably between the 20th and 36th week of amenorrhea. What if the vaccination could not be carried out in this period? Here are the recommendations for protecting newborns.

What are the risks of whooping cough in newborns?

Whooping cough is a highly contagious respiratory disease responsible for exhausting and repeated bouts of coughing over several weeks, which can also cause vomiting. When it tends to be benign in adults, whooping cough is special dangerous in frail people, as well as newborns. As a matter of fact “more than 90% of deaths from whooping cough occur in newborns and children under the age of six months. Between 2013 and 2021, 993 cases of pertussis in children under 12 months had to be hospitalized, including 604 in children under three monthsHAS specifies in a press release dated April 12, 2022.

At what month of pregnancy should you get the whooping cough vaccine?

To protect babies from birth, the Haute Autorité de Santé recommends that expectant mothers be vaccinated from the second trimester of pregnancy, preferably between the 20th and 36th week of amenorrhea (absence of menstruation).. And with good reason: infants are not vaccinated until they are two months old, and partial protection lasts up to three months, “which leaves a window for possible infection in the first few weeks of the child’s life,” explains the HAS, which is responsible for this will integrate this new recommendation into the 2022 vaccination plan. The pregnancy vaccination thus protects the newborn through the transplacental passage of the maternal antipertussis antibodies.

Should I be vaccinated with every pregnancy?

Yes, the HAS recommends that. If the mother was vaccinated before pregnancy, the level of maternal antibodies is not sufficient to ensure passive protection of the infant.

What to do if the pregnant woman was not vaccinated during pregnancy?

If the mother has not been vaccinated during her pregnancy and at least one month before delivery, It is recommended to keep the “cocooning strategy”:

  • The young mother is vaccinated immediately after the birth of the baby, before leaving the maternity ward, even if she is breastfeeding her baby.
  • Vaccination of the environment around the newborn is also recommended at or before birth.
  • Who is affected? Parents, siblings, grandparents and all other people who are likely to have close and constant contact with the infant during the first six months of life.

Is vaccination safe for pregnant women?

“Real data collected abroad for more than 10 years demonstrate the good effectiveness of vaccination of pregnant women to protect infants under three months,” assures the Supreme Health Authority. A good way to reduce especially the risk of hospitalization in babies under 2 months and the risk of mortality in children under 3 months. And according to the various studies, the whooping cough vaccine is well tolerated by pregnant women, with no increased risk of side effects in the expectant mother, fetus or newborn.
