Recommendations

Who should be vaccinated?
Overview
Eligibility summary
  • All adults ≥18 years are recommended to receive COVID-19 vaccine (primary course)
  • Children 6 months–<17 years with medical conditions that increase risk of severe disease
  • Healthy children <18 years are not routinely recommended — risk-benefit does not support it
  • COVID-19 vaccines are currently funded under emergency measures, not the standard NIP
Adults 18–64 (healthy)
Standard schedule
No severe immunocompromise
Primary course & booster schedule
  • Primary course: 1 dose recommended
  • Further doses: Consider 1 further dose every 12 months based on individual preference & risk-benefit assessment
  • Risk of severe illness from COVID-19 is low in previously vaccinated healthy adults
  • 6-monthly dosing is not routinely recommended for this group
Vaccine choice
  • Comirnaty JN.1 ≥12 years formulation (grey cap, pre-filled syringe or multi-dose vial)
  • Comirnaty LP.8.1 ≥12 years formulation (dark grey pre-filled glass syringe)
  • Either mRNA vaccine is appropriate — use latest available formulation
Adults 65–74 years
Annual booster
Without severe immunocompromise
Primary course & booster schedule
  • Primary course: 1 dose recommended
  • Further doses: Recommended every 12 months
  • Can consider doses every 6 months based on risk-benefit assessment
  • 6-monthly dosing is most likely to benefit those with medical risk conditions and/or those in residential care
Vaccine choice
  • Comirnaty JN.1 ≥12 years or Comirnaty LP.8.1 ≥12 years formulation
  • Use latest available updated formulation where possible
Adults ≥75 years
6-monthly booster
⚠️ Priority group — highest risk
Primary course & booster schedule
  • Primary course: 1 dose recommended
  • Further doses: Recommended every 6 months — this applies to ALL adults ≥75, including aged care residents
  • Risk of severe illness increases significantly with advancing age
  • With severe immunocompromise: 2 primary doses recommended (consider a 3rd), further doses every 6 months
Aged care residents
  • All aged care residents fall into the ≥75-year 6-monthly schedule
  • Residence in a care facility is itself a risk factor for severe illness
  • Ensure vaccination records are up to date with ACIR
Severe immunocompromise
Extra doses needed
Any age — modified schedule applies
Primary course schedule
  • Adults ≥18 yrs: 2 primary doses (consider 3rd), at least 8 weeks apart
  • Children 5–<18 yrs: Consider 1–2 primary doses, at least 8 weeks apart
  • Children 6 months–<5 yrs: Consider 2–3 primary doses, at least 8 weeks apart
  • Severe immunocompromise may reduce the immune response to vaccination
Further (booster) doses
  • Adults 18–74 yrs: Every 12 months; can consider every 6 months
  • Adults ≥75 yrs: Every 6 months
  • Children 5–<18 yrs: Consider 1 further dose every 12 months
  • Children <5 yrs: Further doses not routinely recommended
Example severely immunocompromising conditions
  • Haematological malignancies (leukaemia, lymphoma) — untreated or within 6 months of therapy
  • Haematopoietic stem cell transplant or CAR-T therapy within 24 months
  • Solid organ transplant within 12 months
  • Conventional chemotherapy or high-dose immunosuppressants (prednisone ≥20 mg/day, methotrexate >25 mg/wk, mycophenolate, calcineurin inhibitors)
  • Rituximab or B-cell/T-cell targeted monoclonal antibodies
  • HIV with CD4+ <200 cells/μL (adults)
  • Severe primary immunodeficiency (SCID, complete DiGeorge)
  • Chronic kidney disease on dialysis
Medical risk conditions
Increased risk
Without severe immunocompromise
Schedule by age
  • Adults 18–64: 1 primary dose; consider 1 further dose every 12 months
  • Adults 65–74: 1 primary dose; further dose every 12 months (consider 6 monthly)
  • Adults ≥75: 1 primary dose; further dose every 6 months
  • Children 5–<18: Consider 1 primary dose; further doses not routinely recommended
  • Children 6 months–<5: Consider 2 primary doses, 8 weeks apart; further doses not recommended
Example medical risk conditions
  • Cardiac disease (congenital heart disease, congestive heart failure, coronary artery disease)
  • Chronic respiratory conditions (severe asthma, cystic fibrosis, COPD, bronchiectasis)
  • Chronic neurological conditions (hereditary/degenerative CNS disease, seizure disorders)
  • Chronic metabolic conditions (type 1 or 2 diabetes, mitochondrial disorders)
  • Chronic kidney disease (eGFR <30 mL/min, stage 4–5)
  • Haematological disorders (sickle cell disease)
  • Chronic liver disease (cirrhosis, progressive liver disease >6 months)
  • Chromosomal abnormality (Trisomy 21)
  • Obesity (BMI ≥30 kg/m²)
  • HIV infection not meeting severe immunocompromise criteria
Pregnancy
Recommended (unvaccinated)
Recommendations for pregnant women
  • Unvaccinated pregnant women: Primary dose of COVID-19 vaccine is recommended — can be given at any time during pregnancy
  • Previously vaccinated & pregnant: Not routinely recommended for a further dose. However, can consider based on underlying risk conditions and/or personal preference
  • Dose administered during pregnancy may provide some infant protection via transplacental antibodies — but risk of severe illness in healthy infants is extremely low
  • Comirnaty JN.1 and LP.8.1-based vaccines are considered suitable and safe for use in pregnancy by ATAGI
  • mRNA COVID-19 vaccines are safe in pregnancy — adverse event profile is similar to non-pregnant women
Co-administration with other vaccines in pregnancy
  • COVID-19 vaccines (mRNA) can be co-administered with influenza vaccine in pregnancy
  • Discuss timing with maternal pertussis (20–32 weeks) and RSV vaccines (28–36 weeks)
Children with medical risk
6 months–17 years
Not recommended for healthy children <18
Schedule by age group
  • 6 months–<5 years (medical risk, not severe immunocompromise): Consider 2 doses at least 8 weeks apart; further doses not recommended
  • 5–<18 years (medical risk, not severe immunocompromise): Consider 1 primary dose; further doses not recommended
  • 5–<18 years (with severe immunocompromise): Consider 1–2 primary doses; consider 1 further dose every 12 months
Vaccine formulations for children
  • 6 months–<5 years: Comirnaty JN.1 or LP.8.1 yellow cap (3 µg per dose, requires dilution)
  • 5–<12 years: Comirnaty JN.1 or LP.8.1 light blue cap (10 µg per dose, no dilution)
  • ≥12 years: Comirnaty JN.1 or LP.8.1 ≥12 year formulation (30 µg per dose)
  • Children who turn 5 or 12 between doses: use the formulation appropriate for their age on the day of vaccination
Previously vaccinated
Further doses
When to give the next dose
  • There is no recommended minimum interval between a COVID-19 vaccine dose and a prior SARS-CoV-2 infection — proceed with next dose as per schedule
  • A greater interval between infection and next vaccination may enhance hybrid immunity
  • Prior COVID-19 infection does not replace a recommended dose — continue with the schedule
  • Serological testing (antibody levels) is not recommended to guide dose decisions — no assay provides a definitive correlate of protection
Interchangeability of brands
  • Prefer the same brand for the primary course (especially in immunocompromised)
  • Use a different brand if: contraindication to previous brand; previous brand unavailable; patient cannot access or refuses same brand
  • Mixed schedule recommended interval: 8–12 weeks between doses, regardless of brands used
  • Doses do not need to be repeated if the interval is >12 weeks
Contraindications & precautions
Must check
Absolute contraindications
  • Anaphylaxis after a previous dose of a COVID-19 vaccine from the same class
  • Anaphylaxis after any component of that COVID-19 vaccine
  • Anaphylaxis after any mRNA COVID-19 vaccine is a contraindication to all mRNA COVID-19 vaccines
Precautions (seek specialist advice)
  • Recent myocarditis or pericarditis (within past 3 months) — discuss timing with GP/cardiologist
  • Acute rheumatic fever or acute rheumatic heart disease with active myocardial inflammation
  • Acute decompensated heart failure
  • People who develop myocarditis/pericarditis after a COVID-19 vaccine should defer further doses and discuss with treating doctor
Myocarditis / pericarditis awareness
  • Very rare but reported after all currently available COVID-19 vaccines
  • Highest incidence: adolescent males after second dose of mRNA vaccine
  • No events reported in children aged 6 months–11 years
  • Counsel all recipients on signs/symptoms and advise to seek medical attention if symptoms develop
Vaccine formulations 2025–26
Comirnaty
Currently available vaccines
  • Comirnaty JN.1 — targets Omicron JN.1 subvariant (Pfizer)
  • Comirnaty LP.8.1 — targets Omicron LP.8.1 subvariant (Pfizer); recently registered
  • Both vaccines are mRNA-based, intramuscular injection (0.3 mL dose)
  • All currently available COVID-19 vaccines are registered formulations with the TGA
Age-based formulation guide
  • 6 months–<5 years (yellow cap): 3 µg mRNA; multi-dose vial — requires dilution with 0.9% NaCl
  • 5–<12 years (light blue cap): 10 µg mRNA; single-dose vial — no dilution required
  • ≥12 years (grey / dark grey cap): 30 µg mRNA; pre-filled syringe or multi-dose vial
  • Once a multi-dose vial is punctured, use within 6 hours
  • Do not shake vials. Minimise light exposure. Do not refreeze thawed vaccine
Co-administration with other vaccines
  • COVID-19 vaccines can be co-administered with influenza and other vaccines in people aged ≥5 years
  • For children 6 months–<5 years: prefer to separate by 7–14 days (can co-administer if logistically challenging)
  • If MVA-BN (mpox) vaccine is not urgent: consider spacing ≥4 weeks apart from mRNA COVID-19 vaccine — particularly in young males
