Introduction of a New Pneumococcal Vaccine in Australia: Key Facts
Australia introduces an advanced pneumococcal vaccine to the National Immunization Program, offering broader protection for children and reducing the risk of serious infections including meningitis and pneumonia.
The Australian government recently announced the addition of a new pneumococcal vaccine to the National Immunization Program, targeting all children to better protect against pneumococcal disease. This updated vaccine replaces earlier versions, offering enhanced protection against multiple strains of the bacteria Streptococcus pneumoniae, known to cause a spectrum of infections.
Pneumococcal disease includes illnesses such as meningitis, bacteremia, pneumonia, and middle ear infections. It is caused by pneumococcus bacteria, which can be particularly severe in young children, older adults, and individuals with weakened immune systems or certain medical conditions. Globally, more than 100 strains of pneumococcus exist, with some more likely to cause disease.
In Australia, health professionals are required to report cases of invasive pneumococcal disease to state health authorities, with around 2,400 cases reported in 2024, including a significant number in children. The disease spreads via respiratory droplets, especially when the bacteria colonize the back of the nose without causing symptoms.
Vaccination remains a crucial preventive measure. Existing vaccines include the polysaccharide 23-valent vaccine (23vPPV), which has short-term efficacy and targets many strains, and conjugate vaccines (PCVs), which evoke a more robust and long-lasting immune response. The newer 20-valent PCV (20vPCV), recently licensed in Australia, offers broader protection and is expected to prevent approximately 25-30% more cases of invasive pneumococcal disease in children than previous formulations.
The dosing schedule for the 20vPCV involves three doses at two, four, and twelve months, with an additional dose at six months for high-risk groups, including Indigenous children and those with medical risk factors. This new vaccine simplifies the immunization process by eliminating the need for the older 23vPPV in children and continues to provide substantial indirect community benefits by reducing bacterial transmission.
Clinical trials have shown that 20vPCV has a safety profile similar to the longstanding 13vPCV, with high efficacy against multiple strains, making it a vital addition to routine childhood immunizations in Australia.
