A study from the Baylor College of Medicine has shown that new-born children received immunity from pertussis at birth and for the first few months of their life if their mothers had received the tetanus, diphtheria and acellular pertussis (Tdap) vaccine during pregnancy. This will help to combat rising cases of whooping coughs in infants by protecting children during their first two months: the time at which they are most vulnerable to pertussis.
This is good news as the earliest that children can be vaccinated against whooping cough is at two months of age through the DTap vaccine.
After whooping cases in children under 2 began to rise, the Centre for Disease Control and Prevention issued a recommendation that pregnant women receive Tdap vaccinations in order to compensate for the loss of immunity since their childhood vaccinations.
The research, published in the Journal of the American Medical Association, found that the Tdap vaccine is safe for pregnant women and produced an immune response similar in strength to the immunity developed by non-pregnant women. Infants whose mothers had received the vaccine were significantly more likely host higher concentrations of pertussis antibodies in the first two months.
