What should you know about inactivated whole virion vaccine?

The vaccine presents the immune system with a whole virus particle after it has been rendered inactive. This helps the body recognise features of that virus and prepare protective responses without using a live, multiplying virus. It cannot give you the infection it is designed to prevent, although temporary soreness, tiredness or a mild fever can occur after vaccination.

The exact schedule depends on the vaccine, your age, previous doses, health conditions and the infection being prevented. Immunity develops after the recommended course rather than immediately after an injection.

Bring your vaccination record and tell the clinician about previous reactions, pregnancy, immune-system conditions and medicines that affect immunity. Ask which product is being offered, how many doses are planned and when protection is expected. Follow the appointment schedule and keep the record for future travel, school or healthcare visits.

For background, read about [Inactivated Vaccine](/materials/inactivated-vaccine/). Depending on the indication, related services include [Childhood Immunisation](/treatments/preventive-care-and-vaccination/childhood-immunisation/), [Hepatitis A Vaccination](/treatments/preventive-care-and-vaccination/hepatitis-a-vaccination/) and [Hepatitis B Vaccination](/treatments/preventive-care-and-vaccination/hepatitis-b-vaccination/).

Seek urgent medical help for trouble breathing, swelling of the face or throat, collapse or widespread hives soon after vaccination. Contact a clinician about a high or persistent fever, worsening pain, or symptoms that concern you. A mild local reaction often settles as the immune response matures, but a clinician can assess symptoms that are severe or unusual.

Which infection does this vaccine prevent, and why is this formulation suitable for me? What schedule should I follow, and what should I do if a dose is delayed? Which reactions are expected, and which require urgent assessment?
