Pregnant women are urged to get the whooping cough (pertussis) vaccine.
Research has shown that newborns with immunised mothers have a 91pc reduced risk of contracting the disease.
Vaccinating pregnant women enables them to pass immunity to their unborn child, which persists in the period following birth.
The baby can receive their own dose of the vaccine at eight weeks of age.
The antibodies you develop after vaccination decline over time so you need to get the vaccine again in your next pregnancy.
The advice is to get whooping cough vaccine during every pregnancy so that high levels of these antibodies are passed to each baby in the womb.
The vaccine is free but there is an administration fee.
