"To fully protect a child from preventable disease, the mother must be vaccinated during pregnancy and the child at six weeks, three months, 15 months, and at the ages of 4, 11, and 12," she said.
Mrs Hina said it "can't be stressed enough how important it is" for children to complete their full course of vaccines to protect against diseases such as measles and whooping cough.
"It's been very pleasing to receive results showing that 92 per cent of Whanganui's 8-month-olds and 94 per cent of 2-year-olds are fully immunised on time.
"This is a reflection of our local families/whanau making a proactive choice to protect their children."
Healthy, pregnant women are up to 18 times more likely to be admitted to hospital with the flu than non-pregnant women. The vaccine can be given at any time during a woman's pregnancy and there are no safety concerns.
School clinics for Year 7 and 8 student vaccinations for Boostrix and HPV will run from May 16 to June 10. Parents are asked to return their consent forms to their children's school as soon as possible.
"Boostrix protects against tetanus, diphtheria and pertussis, while the Gardasil HPV vaccine protects against multiple cancers and other conditions such as genital warts and recurrent respiratory papillomatosis," Whanganui District Health Board immunisation coordinator Karen Page said.
