COVID-19 vaccine additional doses
Ngā pota whakakaha o te kano āraimate KOWHEORI-19

We know that your protection from the vaccine decreases over time.

To keep your immunity levels high, stay up to date with your immunisations — including additional doses. This will lower your chances of getting very sick from COVID-19 and ending up in hospital.

From 20 January 2025, we use the Pfizer JN.1 monovalent vaccine. This is an updated vaccine targeting recent strains. COVID-19 vaccines are free.

The vaccine produces an immune response against the subvariant, JN.1.

Current evidence indicates the vaccine is more effective against circulating subvariants than earlier vaccines. 

If you are 30 years of age and over, you can have an additional dose regardless of the number of vaccines you have already had. It is recommended:

• you wait at least 6 months since you had COVID-19
• you wait at least 6 months since you had a COVID-19 vaccine.

If you are unsure if you have had COVID-19 recently or would like to have an additional dose before 6 months, you can discuss this with your vaccinator or healthcare provider.

Additional doses are especially recommended for:

• people aged 65 and older
• Māori and Pacific people aged 50 and older
• residents of aged care facilities
• severely immunocompromised people 
• people aged 12 years and over who have a medical condition that increases the risk of severe illness from COVID-19. 

Healthy people aged 16 to 29 can have 1 additional dose.

To get an additional dose: 

• you must have had at least your 2 initial COVID-19 immunisations
• it is recommended you wait at least 6 months since your last COVID-19 vaccine or infection.

Additional doses for 16 to 29 year olds at high risk

Some people aged 16 to 29 can have additional doses.

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. 

If you have other health conditions not included in this list, you can discuss with your vaccinator or healthcare provider to see if an additional dose is recommended for you.

Most tamariki under 16 years old are not eligible for additional doses. 

Young people and tamariki who have a medical condition that increases the risk of severe illness from COVID-19 can get additional doses — this includes pregnant people.

Tamariki aged 6 months to 4 years old who are eligible for the COVID-19 vaccine due to a health condition are also eligible for additional doses.

How many COVID-19 vaccines to get and when — eligibility criteria

Discuss with your vaccinator or healthcare provider to see if an additional dose is recommended.

Having COVID-19 does not provide the same level of immunity as getting immunised.

If you have had COVID-19 and are eligible for an additional dose, it is recommended you wait 6 months after you tested positive.

If you are unsure if you have had COVID-19 recently or would like to have an additional dose before 6 months, you can discuss this with your vaccinator or healthcare provider.

Why you need to wait between infection and immunisation

After you have had COVID-19 your antibody levels will be high from your immune system’s response to the infection. This will give you some protection against COVID-19.

After 6 months, your antibody levels have likely dropped and, if you are due to have a vaccine, it is a good time to boost your immunity.

If you get a vaccine soon after you have had COVID-19, you may not get all the benefits from it because your antibody levels are already high.

If you are at higher risk of severe illness from COVID-19, we recommend you talk to your doctor or specialist for advice on the timing of your next dose. It may be appropriate for you to get your COVID-19 vaccine sooner than 6 months.
