While I'm not necessarily disagreeing with your idea, couldn't you make the opposite case as well? Namely that since the AstraZeneca vaccine is mostly British, the government of that country has an interest in hiding/downplaying potentially harmful side-effects?
As far as I know by now a bunch of European countries have already suspended vaccination with the AstraZeneca vaccine. These include France, Germany, Italy and the Netherlands - not really a politically homogeneous bunch.
