According to: https://beta.health.gov.au/health-topics/meningococcal-disease
People at most risk are teenagers and young adults between 15 and 24 years old.

However, the Tasmanian Government only allows free vaccines for Tasmanians aged between 6 weeks and 21 years old, born after August 1, 1997. This contradicts the point of vaccination, which is herd immunity. Herd immunity is less effective if 33% of the "at risk" population is not vaccinated.

This also greatly increases individual risk of contracting the disease.

The vaccination at doctors around Tasmania can cost up to $300. Many young Tasmanians simply cannot afford this.

I personally am 21, born on the 26th of May 1997, and I don't want to contract a disease because I am 2 months too old and may not be able to afford the vaccine.

I write to Michael Pervan, Department Executive for the DHHS in Tasmania to reconsider the age limit for free vaccinations against the Meningococcal W disease.
