Fianna Fail leader Michael Martin has said he has met similar resistance by public health staff during the polio scandal.
The scandal that Deputy Martin was referring was in 2001, during his time as Minister for Health, 12,000 children received an out of date vaccine.
A significant amount of oral polio vaccine was administered after its expiry date in a period from January 1998 to December 2000.
It contained human serum albumin produced from a plasma pool in which one of the original donors was diagnosed as having the vCJD.
Investigations into this matter led to the discovery that thousands had received expired vaccine with worst offending region for administering that vaccine was in the south of the country.
Speaking to Eamon he said that during his time of finding out about the out of date polio vaccine, there were elements within the public health area who felt it would damage the vaccination program.
“That sense of we must protect the programme, we must protect the screening program.
“There is a view and culture there within the medical world that it takes precedence over transparency with the public and with those who have may been affected,” said Deputy Martin.
He believes that full transparency is now needed and that all documents relating to cervical check should be published.
“We don’t have to wait for an inquiry and I said to the minister please don’t use this inquiry as a bases for burying all these memos and information that might be there within the system.”
