Senator O'Keeffe raised the important issue of illegal vaccine trials which were carried out in several children's homes and requested that the relevant files from the homes in question be handed over to the Health Service Executive and State. She also posed a comprehensive list of questions for the Minister for Health and his Ministers of State. I will be pleased to pass on her questions to the relevant Ministers. This is an important issue and the families of those affected need answers to the key questions Senator O'Keeffe raised.
