Eh? No. Where did you get that? AZ's production shortfall isn't just an EU thing; it's general. The other manufacturers have no such issues; Pfizer-Biontec has actually been able to exceed promised production.
Keep in mind that AZ vaccine is not for profit so bureaucrats do not have many ways to make money from it and in their interest is pushing more expensive ones. This way you can explain the wave of fake news about blood clots and individual countries stopping vaccinations with AZ and scaring the public.
