Figure 2c is a line graph showing frequently suspected vaccines (7vPCV, rotavirus, pH1N1, DTPa-IPV, hexavalent vaccine, seasonal influenza, and 13vPCV) for adverse events following immunisation for children aged <1 year, by year (2000 to 2012), by quarter of vaccination. An increase was observed in estimated reporting rates for rotavirus and in < 7 year old children in 2012 compared with 2011, but it was not statistically significant.
