A mother who lost a four-week-old baby to whooping cough has called on the state and federal governments to do more to promote vaccination.

The call came as NSW's Health Care Complaints Commission (HCCC) issued a warning against the Australian Vaccination Network (AVN), which campaigns against vaccination, after it allegedly used the baby's death to promote its opposition.

Dana McCaffery ... died from whooping cough aged four weeks.

In March last year, Toni and David McCaffery lost their four-week-old baby Dana to whooping cough.

Shortly afterwards they learnt that Dana's death was being used as part of an anti-vaccination campaign.
