Sarah Walton was left severely disabled when the measles infection she had as a child returned 24 years later.

Her mother Jo says she feels she cheated her daughter because she did not know more about the benefits of vaccinating her.

She had not been planning to take up the vaccine for Sarah, when her daughter contracted measles at 11 months old.

Now she says the government should consider penalties against parents who choose not to vaccinate their children.
