Eight vaccines linked to a lower risk of dementia 

Gavi has reported that a number of large observational studies have shown that routine adult vaccines are associated with a reduced risk of dementia, with some indicating risk reductions of up to 40%. 

The largest body of evidence exists for shingles, flu, RSV, pneumococcal, and diphtheria, tetanus and pertussis-containing (DTP) vaccines. 

Researchers believe that the risk reduction is most likely caused by the prevention of infections causing brain inflammation. Some theories also posit the idea of non-specific immunity: the idea that vaccines can have broader effects on the immune system beyond just protecting against a single pathogen.  

Discussing the broader, long-term positive health effects of vaccination with patients can help encourage timely uptake.

Introduction of AIR due and overdue rules for influenza  

The Australian Immunisation Register (AIR) has introduced annual due and overdue rules for influenza vaccines. These rules will help vaccination providers identify individuals who may be eligible for free influenza vaccines under the National Immunisation Program (NIP). 

If an influenza vaccine has not been administered since 1 March of the current year, a dose will show as: 

  • Due on 1 May 
  • Overdue on 1 June 

Individuals will no longer display as due or overdue for influenza after 31 January of the following year.  

The due and overdue rules will be applied each year for individuals eligible for an NIP-funded influenza vaccine. 

Poliovirus found in wastewater in Western Australia 

Poliovirus has been detected in a wastewater sample in Perth.

While this is an environmental detection, not a confirmed case, and the risk to community remains very low, it is a timely reminder to check that your patients are protected and up to date with routine vaccinations.

Vaccination is the best preparation: childhood and winter resources 

The Department of Health, Disability and Ageing have launched two national immunisation campaigns aimed at addressing declining vaccination rates.  

The childhood immunisation campaign collates information for parents, carers and family members on routine childhood vaccinations.

The winter vaccination campaign reminds older Australians about the importance of vaccination against serious respiratory illnesses such as influenza, RSV and COVID-19.
