Jacqui Smith: Information about emergency calls to the ambulance service is not available specifically for the East Riding of Yorkshire. Information about the number of emergency calls and the proportion of emergency calls resulting in an ambulance arriving at the scene of the reported incident within the Government's target response times for Tees, East and North Yorkshire Ambulance Service NHS Trust, is contained in the Department of Health Statistical Bulletin, Ambulance Services, England 200001.
Ms Blears [holding answer 23 April 2002]: None. As announced on 15 January 2002, strategic health authorities, together with their primary care trusts, will review the position of their local ambulance services and will make recommendations to the director of health and social care in the south, by September 2002.
Jacqui Smith: In the last 12 months (April 2001 to March 2002), NHS Direct Tees, east and north Yorkshire has handled 217,500 calls. For the corresponding time period in the previous 12 months (April 2000 to March 2001), NHS Direct Tees, east and north Yorkshire handled 54,000 calls. This represents a 301 per cent. increase in call volumes.
David Davis: To ask the Secretary of State for Health what proportion of patients were seen by a doctor or consultant within one hour of their arrival at accident and emergency in Hull and the east riding in (a) 2002 to the latest available date and (b) each of the last three years. 
Jacqui Smith: Between 2 May 2001 and 31 March 2002, there were 86,924 new attendances recorded in the accident and emergency department of Hull Royal infirmary. Included in this figure are 4,044 records where waiting time information is not available. Of the remainder, 356,259 (42 per cent.) were seen by a doctor within an hour of arrival.

Ms Blears: No assessment has been made of the cost effectiveness of naltrexone in the rehabilitation of heroin addicts. Any potential future analysis would be carried out by the National Treatment Agency (NTA). This would most likely be made in consultation with the National Institute for Clinical Excellence (NICE). Naltrexone (as described in the British National Formulary) is given as an 'adjunct' to prevent relapse so that cost-effectiveness would need to address the context of use. In general terms there is little evidence on how long naltrexone should be used to remain effective in rehabilitation so adequate data on cost-effectiveness for this indication is unlikely to be available at present.
Mr. Hutton: The Government have decided that details of its medical countermeasures for response to any possible biological or chemical attack, and any tendering process for these, should not be put in the public domain, as this is information that could be useful to terrorists.
The tender for the supply of medical countermeasures, including vaccination, for response to any possible biological attack, fall outside the usual open competitive tendering process. There are specific exemptions from the usual process allowed for on the grounds of protection of the interests of national security.

Mr. Bercow: To ask the Secretary of State for Health what assessment he has made of the cost-effectiveness of the Children (Leaving Care) Act 2000 (Commencement No. 2 and Consequential Provisions) Order 2001; and if he will make a statement. 
Jacqui Smith: Costs associated with regulatory proposals are considered at the policy development stage. A regulatory impact assessment (RIA) is completed for regulatory proposals unless there are no or negligible costs, and sets out the impact, in terms of costs, benefits and risks of the proposed regulation which could affect businesses, charities or the voluntary sector. RIAs are available from the Library.
We have yet to have a full year's operation of the Children (Leaving Care) Act, as it was introduced in October 2001. In addition, we have commissioned an evaluation on costs and outcomes for care leavers from the University of York, which will report early in 2004.
Mr. Burns: To ask the Secretary of State for Health when the advice from the Joint Committee on Vaccination and Immunisation on the trials on the vaccine's suitability for the immunisation of all children under 2 against pneumococcal disease will be available. 
Yvette Cooper: Trials to investigate how pneumococcal conjugate vaccines could be incorporated into the UK infant immunisation schedule are in progress and will be completed late this year. These studies are assessing the compatibility of giving pneumococcal conjugate vaccines at the same time as other paediatric vaccines, including meningococcal C conjugate vaccine, and whether three doses in infancy plus a booster is necessary.

Women who are trying to conceive or who are likely to become pregnant, are advised to take a daily 400 micrograms supplement of folic acid until the twelfth week of pregnancy. In addition, all women who may become pregnant are advised to increase their daily intake of folic acid by eating more folate-rich foods and foods fortified with folic acidespecially breads and breakfast cereals.
To prevent the recurrence of a neural tube defect, folic acid supplements at a daily dose of five milligrams (5000 micrograms) are advised and this can be reduced to four milligrams, if this dose becomes available.
