Vaccination is only effective for a few years, so booster vaccinations are essential. It is recommended therefore to perform vaccination during each pregnancy (from the second trimester onwards). This will increase the levels of protective maternal antibodies transferred to the baby and prevent the mother passing whooping cough on to her child after birth.lt is also recommended to vaccinate any people who will come into contact with the infant (father, brothers and sisters, grandparents) if the last whooping cough vaccine was administered more than ten years ago.
