What is the polio vaccine made of?

Inactivated means the virus material in IPV cannot reproduce and cause polio. The formulation also contains small amounts of inactive supporting ingredients that help keep the vaccine stable and suitable for injection. Exact ingredients can vary between manufacturers and combination products, so the product information is the most precise source for a particular dose.

Tell the vaccinator about previous vaccine reactions, severe allergies, immune-system conditions, and any current illness. Bring the vaccination record and ask which product is planned. A mild illness does not always prevent vaccination, but the clinician should decide whether to proceed and whether a different formulation is needed.

Get urgent help if severe allergy symptoms develop, such as trouble breathing, facial or throat swelling, fainting, or rapidly spreading hives. Injection-site tenderness or a short-lived fever can occur. Contact a healthcare professional when a reaction is severe, persistent, or difficult to distinguish from another illness.

Ask whether the planned product is IPV, which ingredients are relevant to your medical history, and whether it is a combination vaccine. If there has been a past reaction, ask how the team will assess it and record the plan for future doses.
