Figure 2 shows trends in vaccination coverage estimates for individual vaccines at 12 months of age from 2003-2014. DTPa and polio coverage at 12 months of age remained relatively stable from 2003 to 2012 and then decreased slightly during 2013 but increased slightly during 2014. Coverage for the Hib and hepatitis B vaccines at 12 months of age (prior to the change in algorithm to measure coverage that occurred in the latter half of 2009) are similar to those for DTPa and polio in the last two cohorts of 2009 and on to 2014. Coverage for 13vPCV rose steadily from below 90% in mid-2007 to be just below that for all other vaccines due at this age at around 90%, except for rotavirus vaccine. Rotavirus vaccine coverage rose steeply from late 2008 from below 70% to almost 84% in late 2011 but then decreased during 2013 before increasing by a percentage point in 2014.
