People eligible for free influenza immunisation have only a short time left to be vaccinated before the Government-subsidised campaign ends for this year on August 31.
The National Influenza Specialist Group said as at August 1 more than 1.2 million doses of vaccine had been distributed this year resulting in an estimated 27 per cent of the population receiving immunisation.
Group spokeswoman and general practitioner Dr Nikki Turner said it was still worthwhile being immunised, even this late in the season.
