Pregnant women in the Southwest will be provided with a free whooping cough (pertussis) vaccination from July 1.
The vaccine will be available for pregnant women nationally and protects both the mother and unborn baby.
The pertussis vaccine will be added to the National Immunisation Program for the first time, after a $39.5 million investment from the federal government.
Member for Forrest Nola Marino said the government's investment has guaranteed the access, safety and availability of the vaccine.
“Whooping cough is a terrible disease that can cause life-threatening complications, including pneumonia or brain damage. Babies in their first six months of life are most at risk,” Mrs Marino said.
“Newborns cannot be vaccinated until six weeks of age and the most effective way to protect a baby against the disease is vaccination of the mother during pregnancy.
“Whooping cough is a vaccine preventable disease and I urge all South West mums-to-be to get vaccinated.”
The free vaccine will be available from 1 July 2018 for all pregnant women.
