12,839 parents/carers responded to an SMS about their child’s health a few days after their 4-year vaccinations. 81% reported no adverse events. 19% reported any adverse event, including 1.7% who reported taking their child to a doctor or emergency department in the days after vaccination. The adverse events they reported were similar to the types of adverse events reported overall. 2,452 parents/carers reported one or more adverse events. The most commonly reported were: injection site swelling or redness (1,114 reports), injection site pain (904 reports), fever (770 reports), tiredness (560 reports) and irritability (514 reports). These symptoms are known to occur after vaccination. They are generally mild and short-lived. These symptoms are also common in young children for other reasons (such as viral infection) and may not be related to vaccination. Aboriginal and Torres Strait Islander children who received these vaccines had the same rates and types of adverse events as other children.
