Figure 6 shows a comparison of coverage of varicella vaccine assessed in 2012 at 24 months of age versus 36 months of age by state or territory. As the 18-month schedule point was historically associated with lower coverage, as there is only a 6-month time period to catch up for varicella vaccination, and as there is the possibility that parents may delay the varicella vaccination varicella coverage estimates assessed at 24 months were compared to estimates assessed at 36 months by jurisdiction. The differences in the expected increases in coverage varied by jurisdiction from a 5.6 percentage points increase in Western Australia to a 2.6 percentage points increase in the Australian Capital Territory. Three jurisdictions reach 90% varicella coverage or very close to 90% when the vaccine is assessed at 36 months.
