KELSON Smith, 4, starts school this year at Rangeville State School.

His mother Emma Smith is feeling a lot more comfortable about it since the Federal Government introduced the no jab, no pay laws.

As of January 1, parents without a medical exemption who don't immunise their children won't be eligible for childcare benefits and other rebates.

"I've done my own research and I think immunisation is the best thing you can do for your kids," Ms Smith said.

"I just don't understand why you wouldn't do it. Even though immunisations aren't 100 per cent effective, there are no benefits to not getting them done at all.

"There's a fair few people who don't believe in it and it freaks me out."

However, Cambooya woman Rebecca Anderson is "deeply disturbed" by the government's introduction of no jab, no pay laws.

"If parents truly believe through their own research that some vaccinations are unsafe for their children, they should not be coerced by financial need," she said.

"If they are going to such extreme measures to vaccinate all children, they need to think about why they need to be so extreme.

"There's a lot of research that doctors and nurses don't talk about because they are afraid of losing their jobs."
