Bay of Plenty residents eligible for free influenza immunisation have until August 31 to get vaccinated before the Government-subsidised campaign ends for this year.

Medical officer of health Jim Miller says this year's influenza season has started later than usual this year and there may be worse to come.

People are encouraged to get their free vaccination before August 31.

The A (H1N1) strain of influenza has been most common across the country and is being picked up in the Bay region, he says.

'This has been responsible for severe infections in previous outbreaks, but is well covered in this year's vaccine.

'I would encourage people in the higher risk groups to have the flu vaccine while it is still free - it isn't too late to make sure you and your family are protected.”

Jim says influenza is much more than a ‘bad cold'. It is a serious disease that can lead to complications, especially for people with ongoing medical conditions. Influenza usually has symptoms such as a sudden onset of illness, high fever, headache, a dry cough and illness usually lasts seven-10 days.

Influenza is easily spread through coughing, sneezing and touching contaminated surfaces.

Good hygiene such as covering coughs, using tissues when sneezing and handwashing can help reduce the risk, but immunisation is the best protection for those at most risk.

Influenza vaccinations are free from a doctor or nurse for New Zealanders until the end of August if you are in one of these groups:

• People aged 65 and over
• Anyone under 65 years of age (including children) with long-term health conditions such as heart disease, stroke, diabetes, respiratory disease (including asthma), kidney disease and most cancers

• Pregnant women
• Children aged from six months and up to five years of age who have been hospitalised for respiratory illness or have a history of significant respiratory illness.

Influenza immunisation will be available after August 31 for a charge from a doctor, nurse or in some pharmacies.
