The declining rates of vaccination in Australia are "very distressing", according to one immunologist, as the federal government looks to tackle declining immunity.
Health Minister Mark Butler launched the national immunisation strategy on Thursday, which aims to increase vaccine uptake and foster community trust.
It's the kind of program that experts have told SBS News is vital in protecting vulnerable communities and children from diseases.
John Dwyer, an immunologist and emeritus professor of medicine at the University of NSW, told SBS News there has been an erosion of trust in vaccines.
"Declining rates of vaccination, especially among children in Australia, are very distressing," he said.
"When you look at what's happening in the US, with the dismissal of top vaccine officials, it's a worry. Misinformation can be spreading not only there but here as well," Dwyer said.
United States health secretary Robert F Kennedy Jr announced on Monday he is removing all 17 sitting members of the Centers for Disease Control and Prevention's vaccine advisory committee and replacing them with new members.
Dwyer said it's necessary for the Australian government to take a proactive approach to improve vaccination rates.
"We've got to counter this misinformation, which is far outweighing the good information that's available through social media," he said.
What are the current childhood vaccination rates?
Data from 2020 to 2024 shows a decline in the vaccination rate among children under the age of five, according to Australia's National Centre for Immunisation Research and Surveillance.
The majority of children in Australia are vaccinated, but the government and experts say the goal is to reach 95 per cent coverage to ensure strong community protection.

Two-year-olds were less likely to be fully vaccinated, with 89.4 per cent in 2024, a 2.7 per cent drop from 2020.
By age five, 92.7 per cent of children were vaccinated in 2024, compared to 94.9 per cent in 2020.
Fully vaccinated coverage for Aboriginal and Torres Strait Islander children continued to decrease in 2024 at all three age milestones.
But the largest drop was recorded at 24 months of age, with coverage declining by 4.5 per cent since 2020.

"This requires a positive campaign that makes people feel comfortable and yes, makes them feel a little guilty if they haven't done the best by their child by vaccinating them."
What's the government's plan?
The national immunisation strategy aims to increase vaccination uptake across Australia over the next five years by reducing vaccine hesitancy and improving access.
The plan outlines priority areas, including enhancing vaccine access in First Nations communities, strengthening the immunisation workforce, and building trust.

This includes the elderly, pregnant women and children.
James Trauer, the head of epidemiological modelling at Monash University's School of Public Health and Preventive Medicine, told SBS News these communities, especially those who may not be eligible for certain vaccines, are the most vulnerable.
"For some infectious diseases, you are really looking to rely on vaccination coverage to totally eliminate the disease or reduce its severity," he said.
"If your vaccination coverage falls below a certain level, you get outbreaks."
"For lots of infectious diseases, you get substantial immunity against infection through the vaccine, and you can totally control them and even reach elimination for many infectious diseases just by reaching high enough coverage," Trauer said.
While 'herd immunity' cannot "totally protect" people from some viruses, such as COVID-19, he said others, like measles, can be "eliminated" from the population.
What if your child has missed a vaccine?
Trauer said each vaccine has specific guidelines for the optimal age at which it should be given to a child.
He said it's essential to consult a specialist about your options.
"I would absolutely recommend that anyone in that situation go and see somebody with expertise in that area.
"It is often possible and advisable to get some sort of catch-up schedule, particularly for the most important infectious diseases."
