South Western Sydney Local Health District Public Health Unit Director Dr Naru Pal said "immunisation saves and transforms lives."
"It is one of the most successful, safe and cost effective health interventions in the history of medicine," Dr Pal said. "Each dose of every vaccine given to babies and children is carefully chosen to provide them with the earliest protection, so it's important to vaccinate on time."
The health district are urging parents and carers to ensure children are vaccinated on time, especially with a spike in measles being experienced across NSW since last year.
Dr Pal said while the region had a high uptake of vaccination (94.5 per cent of children are fully vaccinated by five years of age), the rate was slightly lower at 93 per cent for children aged one year.
"Late vaccinations can put your child at risk of catching a serious disease," he said.
"Children can still get vaccinated if they have a runny nose or slight cold.
Parents and carers can download the Save the Date to Vaccinate app to remind them when children's vaccinations are due. The NSW Immunisation Schedule recommends that children are vaccinated at birth, six weeks, four months, six months, 12 months, 18 months and four years.
The app is free to download from the App Store or the Google Play Store.
