A Scottish parliamentary report into the controversial MMR vaccine was being published today.
The report by Tory health spokesperson Mary Scanlon MSP follows growing fears over the link between the measles, mumps and rubella vaccine and autism.
Mrs Scanlon's report has won the full backing of the cross-party Health and Community Care Committee.
It is expected to call for the Executive to look into the possibility of introducing single vaccines.
Mrs Scanlon says it takes a "calm, very responsible and measured approach to a complex issue".
The Scottish Executive and medical experts insist the vaccine is safe, although a number of MSPs believe parents should be given the choice of a single vaccine.
The committee decided against calling for a full-scale inquiry into the issue last year. Mrs Scanlon has claimed that ministers have tried to undermine the findings of her report.
She said her report had caused rumblings in the background and singled out health minister Susan Deacon as one of the culprits trying to rubbish it.
The MSP has come under attack by the Government's chief medical officer in Scotland, Dr Mac Armstrong, who has made a formal complaint to the health committee.
Dr Armstrong has said that the MSP was inaccessible and had rejected several offers to give medical advice.
