A single vaccine can protect mother and baby from three serious diseases. It is the dTpa, or acellular bacterial triple of the adult type, which immunizes against diphtheria, tetanus and whooping cough.
DTaP is one of the vaccines provided in the pregnancy schedule of pregnant women and should be applied to expectant mothers starting from the 20th week of gestation, with a single dose.
The acellular vaccine is safe for the pregnant woman and the baby.
According to the coordinator of the National Immunization Program (PNI), Carla Domingues, the goal of the PPa vaccine in pregnant women is to reduce the incidence of whooping cough, especially in children under 2 months of age.
"You vaccinate the mother to prevent her from getting sick and pass the disease to her child at birth.
Thus, we do not have vertical transmission, as we call it. It also transmits passive immunity from the mother to the fetus.
At birth, the child will have protective antibodies until he can receive the PT vaccine at Pentavalent, two months of life, "he says.
To receive dTpa, the pregnant woman does not need a prescription. Just look in one of the 36,000 vaccination rooms spread all over Brazil, present the booklet of the pregnant woman and get vaccinated for free.
"From the 20th week, the earlier the pregnant woman gets vaccinated, the more likely she is to create more antibodies," explains Carla Domingues.
Required protection
That's what happened to Karlinda Roriz, 31, mother of little Alice and pregnant with her second son, Lucas. She says vaccines for pregnant women are up-to-date.
"And the dTpa that I've already taken.If I'm not mistaken, it was the twenty-second week of gestation.My doctor has made me aware of its importance, especially for the baby, "says the lawyer.
In the case of pregnant women who, for whatever reason, have not taken the dTpa during the prenatal period, the NIBP recommends receiving the vaccine even during the puerperium – from 0 to 45 days after the birth of the baby.
However, in these cases, the role of the vaccine will be to protect only the mother and prevent her from transmitting the disease to the newborn.
But, the baby will not be able to produce antibodies before vaccination at two months. "The ideal is always to vaccinate during pregnancy," warns the NIP coordinator.
whooping cough
The main goal of the vaccine is protection against whooping cough. This disease, for example, has been very low – less than 10 cases a year.
But in recent years, the disease has increased, especially in children younger than six months.
For this reason, since 2016, the Ministry of Health has started to recommend the vaccination of pregnant women. The goal is to reduce rates again. Pertussis can leave a legacy and cause death.
Cases of diphtheria have also decreased due to vaccination coverage. Same success obtained against neonatal tetanus.
In September 2017, the Pan American Health Organization (PAHO / WHO) declared the elimination of maternal and neonatal tetanus in the Americas.
Vaccination for pregnant women
The Ministry of Health, through the National Immunization Program, offers four vaccines to pregnant women: DPT (diphtheria, tetanus and pertussis); dT (diphtheria and tetanus); hepatitis B; and influenza, is offered during annual campaigns.
In addition to taking care of her health, the pregnant woman transfers the antibodies obtained by the vaccination – first in the placenta, then in breast milk.
This protection is essential in the first months of the child's life, as the immune system develops and strengthens again.
