The body representing midwives has denied claims some midwives are discouraging mothers from getting vaccinated.

Some families claim they've received material discouraging pregnant mothers from getting immunised.

But College of Midwives adviser Norma Campbell refutes the claim saying the college supports immunisation as a public health strategy.

Campbell told Newstalk ZB they work with all other health professionals and the Ministry of Health to provide clear information to women and and their families.

She adds it's up to individual women to make an informed decision about immunisation.
