Figure 3 is a line graph showing trends in vaccination coverage estimates for individual vaccines at 24 months of age (DTPa, polio, Hib, hepatitis B, MMR, Men C, and varicella) in Australia from 1999 to 2011. For most of the study period, hepatitis B coverage was higher than for all other vaccines, at just under 95%, due to the different coverage algorithm described above. Coverage was lowest for MMR and Hib, the only vaccines that have a 12-month dose used in calculations, but in 2011 coverage is similar for all vaccines at around 94-95%, except for varicella vaccine.
