The SmPC documents are available from the Health Products Regulatory Authority (HPRA) and European Medicines Agency (EMA). The list of excipients are usually listed in Section 6. This is called the Summary of Product Characteristics (also called the SmPC). The list of ingredients or excipients for each vaccine can be found in the official licensed documentation for each vaccine. Where can I find a list of the ingredients of a vaccine? None of the multi dose vials of COVID-19 vaccines used in Ireland contain preservatives. Preservatives are not used in the vaccines given as part of the national immunisation programme in Ireland. Preservatives: used in some vaccines that come in vials that contain more than 1 dose. Preservatives keep the vaccine safe and help them to last longer.(you will find more information about this below) Antibiotics: an example of this is neomycin which is used to prevent contamination by bacteria.Inactivating ingredients: an example of this is formaldehyde which is used to kill or inactivate viruses (you will find more information about this below).Cell culture materials: an example of this is egg protein as the antigen is grown in egg protein.Manufacturing by-products: tiny amounts may be found in the vaccine after the manufacturing process.Stabilizers: keeps the vaccine stable and prevent it from breaking into its different parts, an example of a stabiliser is gelatin.An example of an adjuvant is aluminium salts found in the 6 in 1 vaccine. An Adjuvant: found in some vaccines to give us a stronger immune response and may mean that a lower dose of antigen can be used.The Antigen: is the “active ingredient” and it provides immunity.Each excipient serves a specific purpose: Many of the excipients used in vaccines are naturally found in water, food and in our bodies.Įach vaccine contains the active ingredient and also has specific excipients. Excipients have been used in vaccines and other medicines for many years and are known to be safe. An excipient is an additive which is included in tiny amounts in a vaccine.
