[2010 Aug] Ireland's hidden scandal: child vaccine trials  211 children had been administered vaccines during three separate vaccine trials conducted on behalf of a drugs company, The Wellcome Foundation. More than 123 of these infants and toddlers were residents in children's homes in Dublin, Cork and the midlands when the trials took place in the 1960s and 1970s. Trial one involved 58 children in five children's homes in Dublin, Cork, Westmeath and Meath. The trial investigated what would happen if four vaccines -- diphtheria, pertussis (also known as whooping cough), tetanus and polio -- were combined in one overall four-in-one shot. The trial was published in the 'British Medical Journal' in 1962. The final paragraph of it read: "We are indebted to the medical officers in charge of the children's homes. . . for permission to carry out this investigation on infants under their care."   Trial two, which was conducted during the summer of 1970, saw 35 children administered with the intra-nasal rubella vaccine.
