Childhood Vaccines (PE676) PE676, which was submitted by Bill Welsh on behalf of Action Against Autism, calls on the Parliament to urge the Executive to inform all health boards, health practitioners, immunologists and organisations involved in the childhood vaccination programme in Scotland of the opportunity that parents now have to choose the mercury-free vaccine Infanrix instead of vaccines with thiomersal, which contains mercury, for the immunisation of children against diphtheria, tetanus and pertussis.At its meeting on 28 April 2004, the committee considered a response from the Executive and agreed to seek clarification of whether the Executive had informed all health boards, health practitioners, immunologists and organisations involved in the childhood vaccination programme in Scotland about the thiomersal-free option and, if so, by what method.
