Figure 2a is a line graph showing adverse events following immunisation for people aged =7 years for frequently reported vaccines (MenCCV, Seasonal influenza, HPV, pH1N1, and 23vPPV), by year (2000 to 2013), by quarter vaccinated.
•	An increase was observed in reports in 2013 which was partly due to implementation of enhancements to vaccine safety reporting. This included stimulated reporting of AEFI as part of the extension of national HPV vaccination under the National Immunisation Program (NIP) to males.
