Roscommon TD Denis Naughten has called on GlaxoSmithKline to do more than re-releasing vaccine trial summaries on former Mother and Baby Home residents to the state.

GlaxoSmithKline says it has set up an enhanced information service for former residents of the institutions in respect of these trials.

The company says it's in response to issues raised following the publication of the Commission of Investigation's report, which said they had engaged in vaccine trials between 1934 and 1973.

The new enhanced service includes a more simplified information request service, the publication of trial summary documents for nine separate vaccine trials, as well as two infant milk formula trials.

GSK says it recognises that many survivors of mother and baby homes are understandably seeking to access their personal information.

Deputy Denis Naughten told Midwest News that this is not enough and the company should join a redress scheme for former residents of Mother and Baby Homes.
