Is There a Vaccine for Dengue Fever Available in Australia?

Yes, there is a vaccine for dengue fever available in Australia. The vaccine, named Dengvaxia, has been licensed for use in certain populations, primarily aimed at individuals who have previously been infected by the dengue virus. It helps reduce the severity of the disease and is part of the efforts to control outbreaks in endemic areas.

Dengvaxia is a live attenuated vaccine, meaning it uses a weakened form of the virus to stimulate an immune response. It is administered in three doses over a 12-month period. In comparison, traditional vaccines might use inactivated viruses or components of the virus. Dengvaxia is specifically targeted for individuals aged 9 to 45 years who have had at least one previous dengue infection. This approach is important because administering the vaccine to individuals without prior dengue infection may increase the risk of severe dengue upon subsequent infections.

The benefits of the Dengvaxia vaccine are significant. Studies show that it can reduce the incidence of symptomatic dengue by around 56% and severe cases by approximately 88% among vaccinated individuals with prior dengue infection. According to the World Health Organization, vaccination can help lower the burden posed by dengue fever, especially in regions where the virus circulates frequently. It aids in protecting individuals who are at risk of severe disease outcomes.

However, there are some drawbacks to the vaccine. A study published by Sabchareon et al. (2019) highlighted that Dengvaxia may lead to an increased risk of severe dengue in those who have never been infected with the virus before vaccination. For this reason, pre-vaccination testing for previous infection is essential. Furthermore, access to the vaccine can be limited, and not every healthcare provider may offer it.

It is essential for individuals living in or traveling to dengue-endemic areas to consider getting vaccinated, particularly if they have experienced dengue infections in the past. Consulting a healthcare provider for testing and guidance on vaccination is advisable. Those with no prior dengue infection should take additional preventative measures, such as using mosquito repellent and wearing protective clothing, to reduce the risk of contracting the disease.
