Where to find current data on vaccine-preventable diseases

A curated directory of the official live sources — Vic DH, NNDSS, Flutracking, the Doherty Institute. We link you straight to the authoritative dashboards.

Why we don't reproduce the numbers here

Disease surveillance numbers go stale fast and the official dashboards present them better than any third-party page ever could. Below: per disease, what it is, why the vaccine matters, and the two or three places to find the actual current data — all of which we'd link to anyway.

Influenza (flu)

A seasonal respiratory virus that peaks in Australia from May to September. Hospitalises tens of thousands and causes hundreds of deaths in a typical Australian winter — most are preventable with annual vaccination.

Vaccination takeaway

Get an annual flu vaccine in April or May for peak winter protection. Free for everyone over 6 months under the Victorian funded program in 2026.

RSV (respiratory syncytial virus)

A respiratory virus that's a leading cause of hospitalisation in infants under 12 months and adults over 75. Highest risk in the same winter months as flu.

Vaccination takeaway

Maternal RSV vaccination at 28–36 weeks of pregnancy is free on the NIP and protects newborns through their first RSV season. An RSV vaccine is also free for adults aged 75+.

Pertussis (whooping cough)

A highly contagious bacterial respiratory infection. Most dangerous for infants under 6 months — that's why we vaccinate the mother in pregnancy and the people around the baby.

Vaccination takeaway

A dTpa booster is recommended every 10 years for adults — and during every pregnancy, regardless of when the last booster was. Free during pregnancy under the NIP.

Mpox

A viral infection transmitted by close skin-to-skin or mucous-membrane contact. The 2022 global outbreak primarily affected gay and bisexual men; Victorian cases peaked in 2024 and continue at low background levels.

Vaccination takeaway

Two doses of the mpox vaccine, at least 28 days apart, give strong protection. Free in Victoria for eligible people including sexually active gay and bi men, sex workers, people living with HIV, and sexual partners of any of the above.

Measles, mumps and rubella (MMR)

Three highly contagious viral diseases. Measles is one of the most infectious diseases known — one case can spread to 12–18 others in an unvaccinated group. Imported cases linked to overseas travel continue to be detected most months in Australia.

Vaccination takeaway

Adults born after 1965 should have two documented MMR doses. Free for Victorian adults 20–59 under the catch-up program until 30 June 2027.

COVID-19

A respiratory virus that became pandemic in 2020. Now endemic and following a roughly six-monthly wave pattern in Australia. Still causes the most deaths of any respiratory virus in over-65s.

Vaccination takeaway

ATAGI currently recommends a 2026 booster for adults aged 65+, immunocompromised adults, and anyone who would like one. Free under the NIP for eligible groups.

If you have symptoms now

  • Mild respiratory symptoms (cough, runny nose, low fever): rest at home, hydrate, paracetamol or ibuprofen for symptoms. Stay away from infants, pregnant people, and over-65s while symptomatic.
  • Severe or worsening symptoms (difficulty breathing, chest pain, persistent fever >3 days): see your GP or go to a hospital ED. If life-threatening, call 000.
  • Rash + fever, especially after travel or contact with a known case: don't sit in a GP waiting room — phone first so they can isolate you.
  • Possible exposure to mpox or measles: post-exposure vaccination can prevent disease if given quickly. Call us on (03) 9364 7133 or your GP the same day.
