Flu vaccinations in New Zealand will be available a month later than usual this year.
The vaccine is usually out in late February, but will now be on doctors’ shelves at the end of March.
The reason for the month delay is that the vaccination needs to be changed following the sickness in the northern hemisphere this winter.
A particular strain of the virus has proved more troublesome in the northern hemisphere than doctors expected.
It is not expected that the month delay will have much affect on New Zealand.
