The baby daughter of an anti-vaccination activist has been hospitaled with whooping cough after she ignored doctors advice to immunise the 11-week-old girl.

The Melbourne woman bragged on Facebook to fellow anti-vaccination supporters on Friday that she told hospital doctors she would consult a general physician so her sick daughter could be discharged, according to the Sydney Morning Herald.

In the Facebook group Unvaccinated Australia, the unnamed woman wrote that ‘They [doctors] read me the riot act again but they believe me about doing vaccinations through the GP.’

‘I ended up saying I would be talking to a GP about it just to shut them up.’

The mother had allegedly dodged child protection authority’s vaccination inquiries only a week ago.

The woman said she took her daughter to a physician for a health check on December 4 when a maternal nurse noted the infant had flu-like symptoms and asked her to vaccinate the young girl from the potentially deadly disease.

The mother protested that she would see a GP but the nurse contacted child protection services who soon called the woman.

After reiterating the alleged excuse that she would see a physician about immunising her daughter from the disease that kills one in 200 infected children, protection services didn't push the complaint further.

The incident comes after earlier this week one in four students at a North Melbourne primary school were found to be infected with chickenpox.

Up to 80 students at Brunswick North West Primary School, in Melbourne's north, have been infected over the past two weeks since the first cast was reported to Victoria's Department of Health on November 26.

Following the outbreak, outraged parents took to Facebook and Twitter to express their concerns after it was said the school had previously asked families to be 'tolerant' of non-vaccinated children'.

A South Australian woman wrote: 'I'm shocked to see some anti vaxers think that this is good for their kids, that it helps build their immune system.... such a shame that they are too selfish to think that this could kill a few people.'

And Meredith tweeted: 'The pain caused by vaccination is nothing compared to the pain of watching your child died. I know because I've experienced both.'

Professor Jodie McVernon, an expert in infectious diseases from the Murdoch Children's Research Institute, said the trend of parents not immunising their children could lead to a 'national concern'.

'Clearly there's greater opportunity for diseases to spread in areas where immunisation falls below what we call the critical protective threshold,' she told 774 ABC Melbourne.

'That varies for different diseases but generally where immunisation is less than about 95 per cent coverage, there's greater chance for infection to spread.

'We know already there are some areas where immunisation rates are lower and areas exist where people with particular views on immunisation live,' she said.

'It's a national concern that we're trying to address by supporting immunisation and supporting parents in their decision-making.'

A Year 6 student is thought to have contracted the illness before it spread down through to Year 2 students, 7News reported.

The school had previously asked parents and other community members to be tolerant of people's views about immunisation.

'Staff respect the rights of every family to make choices about immunisation and we will definitely not exclude children who are not fully immunised from our service,' the school's December newsletter said.

'We expect all community members to act respectfully and with tolerance when interacting with other parents and carers who may have a differing opinion to their own.

'This includes an opposing understanding about child immunisation.

'People from both sides of the discussion have expressed their thoughts in terms of the well-being and ongoing health of the children they care so much for.'
