(notified under document C(2011) 9398)
(Text with EEA relevance)
(2011/869/EU)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Whereas:
In the interest of public health it is appropriate, where possible, to draw up common technical specifications for the devices listed in List A of Annex II to Directive 98/79/EC.
Taking into account the state of the art and the current scientific knowledge on Variant Creutzfeldt-Jakob disease, common technical specifications can be drawn up for vCJD blood screening assays.
HAS ADOPTED THIS DECISION:
Article 1
The Annex to Decision 2002/364/EC is amended in accordance with the Annex to this Decision.
Article 2
This Decision shall apply from 1st of July 2012.
However, Member States shall allow manufacturers to apply the requirements set out in the Annex before the date set out in the first paragraph of this Article.
Article 3
This Decision is addressed to the Member States.
Done at Brussels, 20 December 2011.
For the Commission
John Dalli
Member of the Commission
