Why getting a flu jab is important if you have an underlying health condition 

As people in Aotearoa emerge from their bubbles, there’s a much bigger chance of catching the flu. Pandemic measures like mask wearing and hand hygiene mean we've had very little influenza circulating in New Zealand for the past two years, so community immunity is lower than usual. And, with international borders opening, we’ll see new strains of flu spreading in our communities.

People with some underlying health conditions are most at risk from the complications of flu.  

Flu can make an existing condition such as asthma, emphysema, heart disease, or diabetes, a lot worse. 

In some cases, flu can put people in hospital, and in severe cases, the flu can be fatal. Around 500 people die from the flu every year.  

Flu can: 

  • affect your blood pressure 
  • increase your risk of having a heart attack or stroke 
  • cause inflammation in the lungs and airways which can trigger asthma attacks 
  • interfere with blood sugar levels 
  • compromise an already weak immune system 
  • cause pneumonia. 

It’s more important than ever to protect yourself from the flu by getting your yearly flu jab as soon as you can.

Getting the flu jab 

You can get your free flu jab from your GP or healthcare provider. Many pharmacies also offer the free flu vaccine for people aged 13 and over.
