HC Deb 26 April 2001 vol 367 cc329-30W
Mr. O'Hara

To ask the Secretary of State for Health (1) how many cases of epilepsy have been recorded between 1 November 1999 and 28 February 2001 related to yellow cards submitted in connection with meningitis C injections; [157552]

(2) what research is being conducted into the incidence of cases of epilepsy which may be related to meningitis C injections. [157549]

On 1 November 1999, a national immunisation campaign commenced to vaccinate all children under 18 years with one of the new meningococcal C conjugate vaccines. The campaign finished at the end of January 2001. As of 16 February 2001, 18.5 million doses of meningitis C vaccine had been distributed.

The Medicines Control Agency and the Committee on Safety of Medicine (CSM) has received three Yellow Card reports of suspected epilepsy following vaccination with the meningococcal C conjugate vaccines. A total of 291 reports of suspected seizures have been reported in association with the meningococcal C conjugate vaccines. CSM has concluded that there have been very rare reports of seizures following meningitis C vaccination and individuals have usually rapidly recovered. A significant number of the reported seizures are thought to have been faints.

A report of a particular suspected adverse drug reaction does not necessarily mean that it has been caused by the drug. The Yellow Card data can not be used to calculate the incidence rate of a particular suspected adverse reaction, nor can it be used to measure changes in the rate against time.

The Medical Research Council has research programmes looking into epilepsy and meningitis, but no program that is examining the incidence of epilepsy after meningococcal C conjugate vaccination.

Mr. O'Hara

To ask the Secretary of State for Health (1) what research he is conducting into the incidence of cases of attention deficit and hyperactivity syndrome which may be related to meningitis C injections; [157550]

(2) what change there has been in recorded cases of attention deficit and hyperactivity disorder between 1 November 1999 and 28 February 2001; [157554]

(3) how many cases of attention deficit and hyperactivity disorder have been recorded between 1 November 1999 and 28 February 2001, which are related to yellow cards submitted in connection with meningitis C injections. [157551]

The Medicines Control Agency (MCA) and the Committee on Safety of Medicine (CSM) has received one report through the Yellow Card Scheme of hyperactivity aggravated in a child with a history of Attention Deficit Hyperactivity Disorder (ADHD) in association with the meningitis C vaccines. There have been no reports of Hyperkinetic Disorder or any other term related to ADHD.

ADHD is being increasingly recognised in the United Kingdom as a significant mental health problem among children and adolescents and to a lesser extent, among adults. The National Institute for Clinical Excellence has estimated that approximately 1 per cent. of all school-aged children (about 69,000 six to 16-year-olds in England) met the diagnostic criteria for Hyperkinetic Disorder, the more severe type of ADHD. The prevalence of all types of ADHD is considerably higher, around 5 per cent. of school-aged children (345,000 six to 16-year-olds in England). There are no data on the change in recorded cases of attention deficit and hyperactivity disorder between 1 November 1999 and 28 February 2001 as this information is not collected centrally.

No research is currently being conducted into the incidence of cases of attention deficit and hyperactivity syndrome which may be related to meningitis C injections.
