Whooping Cough Risk in Older Australians: ATAGI Raises Concern

Whooping Cough Risk in Older Australians: ATAGI Raises Concern

14 Apr 2026

The Australian Technical Advisory Group on Immunisation (ATAGI) has raised concerns that pertussis is not just a childhood illness. It says older adults and people with chronic health conditions face higher risks of serious illness and complications.

The group reports that vaccination coverage is low, with fewer than 37% of adults aged 50–64 and those 65 and over protected against tetanus and diphtheria, and less than 25% vaccinated against pertussis.

ATAGI recommends a dTpa booster (tetanus, diphtheria, and pertussis) every 10 years for healthcare workers and adults aged 65 and over. However, this vaccine is not currently free for these groups under the National Immunisation Program.

At present, free pertussis vaccines are mainly provided for young children, adolescents through school programs, and pregnant women.

Health experts say GPs should start discussing whooping cough vaccination with patients from age 50. They also suggest boosters may be needed every five years for ongoing protection.

Australia recorded more than 82,000 pertussis cases in 2024–25, the highest level since records began in 1991, raising further concern among health authorities.
