manufacturing sites. AstraZeneca shall use its Best Reasonable Efforts to manufacture the Vaccine at manufacturing sites located within EU(which, for the purpose of this Section 5.4 only shall include the United Kingodm) and may manufacture the Vaccine in non-EU facilities if appropriate, to accelerate supply of the Vaccine in Europe; provided, that AstraZeneca shall provide prior written notice of such non-EU manufacturing facilities to the Commission which shall include an explanation for such determination to use non-EU manufacturing facilities. If AstraZeneca is unable to deliver on its intention to manufacture the Initial Europe Doses and/or Optional Doses under this Agreement in the EU, the Commission or the Participating Member States may present to AstraZeneca, CMOs within the EU capable of manufacturing the Vaccine Doses, and AstraZeneca shall use its Best Reasonable Efforts to contract with such proposed CMOs to increase the available manufacturing capacity within the EU. The manufacturing site planning is set out in Schedule A.
Probably needs a lawyer specialised in this stuff and the jurisdiction where the contract is signed, but it seems like this is the part that EU says the contract included the UK facilities.
Anyway, whatever happens people of Europe wont forget this, even if it was purely EU's fault. You don't say you belong to a team, omit the vaccines of China and Russia and then be let to die off because the rest of the team says you should have signed better contract. Next time something important comes up, EU should think beyond the UK/USA.
