To ask the Scottish Executive what current vaccines contain thiomersal or similar heavy metal based preservatives.
The regulation and safety of medicines is reserved and is the responsibility of the Medicines and Healthcare products Regulatory Agency (MHRA). The MHRA has advised that there are currently 102 vaccines licensed in the UK of these 20 contain thiomersal or sodium thimerfonate. Seven vaccines (Anthrax Vaccine, Ad DTP, Act-HIB DTP, Behring Ad T, Behring Ad DT, Evans Ad T, Tritanrix Hep B) contain preservative levels, and 13 vaccines (Tetravac, Pentavac, Fluarix, Engerix B, Fluvirin, Inactivated Flu, Twinrix Adult, Twinrix Paediatric, Infanrix Hexa, Infanrix Penta, Ambirix, Fendrix and Quintanrix) contain residual traces from the manufacturing process.
None of the vaccines are used in the current childhood immunisation programme.
The product information for these products clearly states that thiomersal or sodium thimerfonate is present in the vaccine.
