FIigure1: any delayed immunisation rates, 2004 and 2009
Figure 2: more than 6 months delayed immunisation rates, 2004 and 2009
In Australia, the timely receipt of 2nd dose of MMR vaccination decreased rapidly (Department of Health, 2013). As can be seen from Figure 1, there was a considerable increase of any delayed immunisation rates from 65% in 2004 to 80% in 2009. Especially, the more than 6 months delayed immunisation rate increased sharply from almost 24% to 35%, as shown in Figure 2.

Figure 5: MMR immunisation rates of children 60-63 months of age
Figure 3 shows that Immunisation coverage in Australia as a developed country is 94 per cent, which is lower than those of many developing countries such as Rwanda, Eritrea and Bangladesh (Browne, 2013, May 30). However, there are some regions of Australia where the rates are well below the Australian national average rates. Australia’s MMR immunisation rate of children 24-27 months of age is 93.8%, which is higher than those in both NSW and WA, while Australia’s MMR immunisation rate of children 60-63 months of age is 92.5%, over those rates in SA, WA and NT as well, as shown in Figure 4 and Figure 5 respectively (Medicare, 2013).
Figure 6: the effect of immunisation on economic efficiency. Adapted from “ Essentials of economics” by Hubbard, R. G., 2012
According to Hubbard (2012), in economic view, the immunisation rate is a positive externality that leads to a divergence between private benefits of consumption and social benefits. As can be seen in figure 6, the market
