622. To ask the Minister for Health if his Department will investigate claims that the symptoms of some 650 persons who have received the HPV vaccine here fit in with a recently described phenomenon known as autoimmune inflammatory syndrome induced by adjuvants (details supplied); and if he will make a statement on the matter.

Adjuvants (immune potentiators or immunomodulators) have been used for decades to improve the immune response to vaccine antigens. The incorporation of adjuvants into vaccine formulations is aimed at enhancing, accelerating and prolonging the specific immune response towards the desired response to vaccine antigens. Advantages of adjuvants include the enhancement of the immunogenicity of antigens, modification of the nature of the immune response, the reduction of the antigen amount needed for a successful immunisation, the reduction of the frequency of booster immunisations needed and an improved immune response in the elderly and immunocompromised.

Of the approximately 650 reports of suspected adverse reactions that were received by the Health Products Regulatory Authority and classified as serious, in the majority of these cases the medical care required was for the treatment of vaccination related events, such as fainting around the time of vaccination, or treatment for injection site reactions such as headache, rash, itching (or other allergic-type reactions), fever, muscle pain and gastrointestinal effects, such as nausea and vomiting. Such reactions are typically transient in nature and as such do not represent autoimmune and inflammatory conditions.

My Department has no plans to investigate these claims as the safety and efficacy of these vaccines continues to be monitored by regulatory agencies at both national and European level.
