In a large-scale U.S. study published on Monday, the researchers say that the rate of infants getting whooping cough is much less if their mothers are administered with pertussis vaccine during pregnancy and thereby can shield their unborn from the potentially fatal respiratory infection.
Whooping cough is caused by the bacteria named Bordetella pertussis. It is extremely contagious and can easily spread when an infected person sneezes or coughs. Nearly more than half of the babies under the age one having pertussis needs hospitalization for grave complications such as brain disorders or even pneumonia.
The study that was published in the journal Pediatrics said that medical researchers observed and studies data of nearly 149,000 infants who were born in California from 2010 to 2015. Almost 70,000 mothers had received the Tdap vaccine shot at the time of pregnancy. The researchers concluded that the mothers who got booster vaccine for diphtheria, tetanus and pertussis were 91% less probable to acquire whooping cough, especially during the first two months of being born, which is considered as the most crucial period prior to the U.S. infants generally get their first shot of pertussis vaccine.
Dr. Nicola Klein, the leading author of the Kaiser Permanente Vaccine Center in Oakland, California, insists that it is vital that every pregnant woman must get vaccinated. Healthcare experts across several countries urge getting vaccinated while being pregnant, along with a series of three vaccine shots for the new born beginning anytime between 6 weeks and 3 months of age.
The authors of the study say that their conclusion backs the 2013 recommendation of the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices that every woman must get the vaccination against pertussis at every pregnancy.
The thought was that the newborns would acquire pertussis antibodies from their mother, and shielding them till they were strong enough to get the vaccination. Also, there was significant research that proved the safety of this method, however in anticipation of the Pediatrics study, there was very less evidence of its efficiency.
Dr. Klein says, "I think this really provides a strong amount of support to improve vaccination rates for pregnant women around the country."
Klein also believes that a few scientists have concerns that maternal vaccination can hinder with the efficiency of the Tdap vaccine that guards the kids against pertussis, diphtheria and tetanus. In all children receive five dosages of this immunization vaccine starting at 2 months of age.
The research study determines the opposite effect – post the first, second, and third Tdap shots, children whose mothers got the vaccine were better protected.
Klein said, "We found that the Tdap vaccine seemed to add to the protection that the infants get from their own vaccines."
Department of Public health from California published a study in October 2015, the study discovered that vaccinating pregnant women against pertussis renders higher protection level to the decreased percentage of their newborns who catch the disease.
Of all the newborns whose mother failed to get the vaccination, nearly 3 out of 4 were hospitalized, as per the study.
