To ask the Scottish Executive, further to the answer to question S2W-7038 by Malcolm Chisholm on 1 April 2004, under what circumstances thiomersal would be removed from childhood vaccines as a precautionary measure and whether there are any plans to use the mercury-free vaccine, Infranrix, as an alternative to thiomersal.
As set out in the answer to questionS2W-7038 UK Health Departments are advised by a number of expert committees on mattersrelating to vaccination and immunisation and their advice, which has full regardto issues of safety and effectiveness is, and will continue to be, reflected inthe childhood vaccination programme.
Infranrix is the brand name of the DTaP (diphtheria, tetanus and acellular pertussis) vaccine, currently licensedfor use in the UK. The alternative, recommended, vaccine is DTwP (diphtheria,tetanus and wholecell pertussis) which contains thiomersal. Protection against diphtheria,tetanus and pertussis is currently recommended for babies at two, three and fourmonths and, when administered, the vaccine used is generally combined with a Hibvaccine to protect infants against Haemophilus influenzae type b (Hib) disease.
Based on advice from the JointCommittee on Vaccination and Immunisation (JCVI), UK Health Departments currentlyrecommend DTwP-Hib vaccine, for primary immunisation at 2, 3 and 4 months, as partof the childhood immunisation programme. This is because it has been demonstratedto give more effective protection against whooping cough (pertussis) than the DTaP-Hibalternative. Scientific evidence shows that the combined DTwP-Hib is more efficaciousagainst Hib disease than DTaP-Hib, which provides lower immunity against Hib disease.
Where a child has a valid contraindicationto DTwP, current advice is that he or she should be given DTaP and separate Hibvaccines at the same time but in different limbs. General Practitioners (GPs) areaware that any final decision about immunisation of a child requires the informedconsent of a parent or guardian. In that process, it is appropriate for GPs to makeavailable information on why a particular product is recommended, while recognisingthat it is open to parents to request, and doctors to provide, an alternative vaccine,which is licensed in the UK and available through the NHS.
