HPV vaccine coverage: females and males aged 12-13 years in mid-2013, who received Dose 3 of the vaccine by 2016

 

Policy context:  Two prophylactic human papillomavirus (HPV) vaccines have been developed which can prevent infection and disease due to HPV types 16 and 18, the most cancer-promoting types, which are responsible for 70% of cervical cancers [1].

Australia was the first country in the world to introduce a fully funded, population based HPV vaccination program, the National Human Papillomavirus (HPV) Vaccination Program, which is now an ongoing school-based program for 12-13 year old girls, and most recently, for males of the same ages as well [2][3]. Males aged 14-15 years are also able to receive the vaccine through a catch-up program in 2014 [3].

HPV vaccine coverage data for females and males were provided by the National HPV Vaccination Program Register (NHVPR). The Register was established in 2008 to measure HPV vaccination coverage and support the management and evaluation of the program.

Notes:  The data presented are for females and males who were aged 12 to 13 years as at 30 June 2013, and who received three doses of the HPV vaccination by 29 February 2016. Females and males receiving all three doses represent those fully vaccinated.

Where there were fewer than ten participants in an area, the data are not shown.

Information held by the National HPV Vaccination Program Register is provided to the Register from immunisation providers. The accuracy of the information is dependent on the quality and timeliness of the data provided. Every effort is made to ensure that the information recorded on the Register is up to date and correct.

There are a number of instances in which percentages calculated for an area show as greater than 100% in the data. These may occur as a result of the numerator (the number of females or males vaccinated) being inaccurate where:

  • the data have not been geo-coded, and the geographic area at which the data are available is the postcode; postcode data are allocated to a PHA on the basis of the proportion of the postcode which falls into a PHA, which can result in allocation to the wrong PHA; the conversion is undertaken using approximate allocations of postcode populations (based on the best fit of Census Collection Districts (CDs) to postcode areas) to LGAs, derived from data at the previous Census. In many instances this conversion represents a crude allocation of the population of any LGA. For example, in many cases the boundaries of CDs do not match the boundaries of postcodes, and whole CDs are allocated to the postcode into which the population largely falls;
  • a person’s address is recorded on the register as the place where an event occurred (e.g., a school, GP or immunisation clinic), rather than the person’s home address; or
  • a client is recorded twice on a database or register. This may occur if inadequate information is provided to the register to allow the appropriate matching processes to occur.
