An Australian father has been afforded the legal right to have his kids vaccinated, winning a case against his ex-wife who has a fear for immunizations and thus prevented their children from having them.

The mother, who had since divorced with the father in August 2011, said she refrained having their children, now aged 14- and 12-year-old, vaccinated because of the increased risk of "vaccine damage" due to various allergies.

Known as Mr Randall in court documents, the 52-year old father told the Sydney Morning Herald he actually questioned his ex-wife's views on immunization when they were still together. But then ''for the sake of peace in the household," he would just let her have her way.

After his divorce three years ago from Ms Duke-Randall, it was then that the Australian father realized what his two children had been missing. He saw how his son and daughter missed out on extra-curricular activities just because they were not immunised.

His children were barred by some relatives from socializing with their children. The fear of a possible outbreak of an infectious disease in school also worried him sick.

He said he tried to reason out with their mother but he ''was simply unable to negotiate with [her] on the issue," prompting him to elevate the matter to the Family Court.

When asked about her abhorrence to vaccinations, the 42-year-old woman submitted hundreds of documents about the risks of vaccination, such as the link to autism. However, most of those were only "comments, submissions, irrelevancies," according to Justice Garry Foster.

Mr Foster believed Ms Duke-Randall had become "narrowly focused on it, perhaps to the point where the best interests of her children have been subsumed."

Evidence from tests conducted by a senior consultant in immunology contradicted Ms Duke-Randall's allergy claims. It found both children healthy. They don't have any allergies or any other contraindications to vaccination.
