Additional booster doses

Regardless of how many boosters you have had, you can get an additional booster now if you are: 

  • aged 30 and over  
  • pregnant, and aged 16 or over 
  • aged 12 to 29 and at higher risk of severe illness from COVID-19.

Ages 30 and over

If you are aged 30 and over, you can have a booster regardless of the number of boosters you have already had.

To get a booster:

  • you must have had at least your first 2 COVID-19 vaccinations
  • it’s recommended you wait at least 6 months since your last COVID-19 vaccine
  • it’s recommended you wait at least 6 months if you have had a COVID-19 infection.

Boosters are especially recommended for:

  • all people over 65 years old
  • Māori and Pacific people aged 50 and over
  • pregnant people with health conditions that put them at higher risk of severe illness from COVID-19   
  • people with disability with significant or complex health needs 
  • people with serious mental health conditions  
  • young people aged 12 to 15 who have a medical condition that increases the risk of severe illness from COVID-19 (talk to your usual doctor, nurse, or healthcare provider about whether this is recommended and how to get a prescription).

Ages 16 to 29

Healthy people aged 16 to 29 can have a 1 booster dose.

To get a booster:

  • you must have had at least your first 2 COVID-19 vaccinations, and
  • it’s recommended you wait at least 6 months since your last COVID-19 vaccine or infection.

Additional booster doses for 16 to 29 year olds at high risk

Some people aged 16 to 29 can have an additional booster dose. This includes: 

  • severely immunocompromised people 
  • pregnant people
  • those who have a medical condition that increases the risk of severe illness from COVID-19
  • those who live with disability with significant or complex health needs or multiple comorbidities. 

Ages 12 to 15

Healthy children under 16 years old are not eligible for boosters.

Young people aged 12 to 15 who have a medical condition that increases the risk of severe illness from COVID-19 can get an additional booster dose on prescription. Talk to your doctor, nurse, or healthcare provider about whether this is recommended and how to get a prescription. 


Children 11 years old and under

Children under the age of 12 are not eligible for boosters. However, you can discuss specific clinical circumstances with your doctor, nurse, or healthcare provider.

Children have a good immune response, and are much less likely to get severe disease or need to go to hospital if they get COVID-19.

Which vaccine is used for boosters

For boosters, the bivalent Pfizer vaccine is preferred. This is an updated vaccine targeting Omicron.

If you do not want to have the bivalent vaccine, you can ask for the original Pfizer vaccine when you arrive for your vaccination. 

Adults aged 18 and over can also choose Novavax. This is available at limited sites.

About the Pfizer BA.4/5 bivalent vaccine

The bivalent vaccine makes the immune system create antibodies against both the original variant of SARS-CoV-2 and Omicron subvariants to provide better protection.

The bivalent vaccine is recommended for eligible pregnant people at any stage of pregnancy or during breastfeeding.

Side effects of boosters

You may experience some side effects, similar to those you might’ve had after the first or second dose, such as muscle aches, pain at the injection site, or headaches.

For most people, these are mild effects. They are a sign your body’s immune system is learning to fight the virus. They don’t last long and for many people do not impact day-to-day activities.
