What is pneumococcal vaccine?

Pneumococcal vaccine is used to prevent infections that are caused by the bug (bacteria) called Pneumococcus. These infections can range from sinusitis and ear infections to life-threatening infections like pneumonia or meningitis. Find out more about pneumococcal disease.

Being vaccinated causes your body to produce antibodies against the Pneumococcus bacteria. This means your body can respond faster and more effectively to prevent an infection. It does this because by first coming across a non-infectious version of the bacteria in the vaccine, it learns to recognise it. When it comes across it again, your body can react much faster and in a more effective way.

How effective is pneumococcal vaccine?

Vaccination is the best method for preventing infection and reducing the seriousness of illness if you become infected. The rate of pneumococcal disease in children under the age of 2 years has halved since vaccination was introduced. 

When is pneumococcal vaccine given?

In New Zealand there are 3 different brands of pneumococcal vaccine – Pneumovax 23®, Prevenar ® and Synflorix®.

  • Most infants should receive the pneumococcal vaccine (Synflorix) as part of the New Zealand Immunisation Schedule at 6 weeks, 5 months and 12 months of age. They are not fully protected until they’ve had all the doses.
  • Infants on a high-risk pneumococcal schedule may receive their doses of the pneumococcal vaccine (Prevenar 13) at 6 weeks, 3 months, 5 months and 12 months of age.
  • Some older children and adults with weakened immune systems who are at risk of pneumococcal infection may be eligible for vaccination (Pneumovax 23). Check with your doctor or nurse about your eligibility. 

How is pneumococcal vaccine given?

  • Pneumococcal vaccine is given by injection into a muscle, such as the muscle on your mid-thigh.
  • If you have a condition that makes you bleed more easily than normal, it may be given as an injection underneath your skin.
  • It's safe to get the pneumococcal vaccine at the same time as the seasonal flu vaccine, but at a different injection site.

What are the side effects of pneumococcal vaccine?

Like all medicines, the pneumococcal vaccine can cause side effects, although not everyone gets them.

Where can I get vaccinated?

The best place to go for vaccinations is your family medical clinic. They have your medical records and can check to see if you’ve already had a particular vaccination. Either your doctor or a nurse can give the vaccination.

If you don’t have a family doctor, you can go to one of the after-hour medical clinics. Phone them first to make sure they can help you with the vaccination you need.

You can find a clinic near you on the Healthpoint website. Put in your address and region, and under Select a service, click on GPs/Accident & Urgent Medical Care.

Vaccines on the National Immunisation Schedule are free. Other vaccines are funded only for people at particular risk of disease. You can choose to pay for vaccines that you are not eligible to receive for free.
