It's not reserved to German politicians but the EU democracy apparatus as a whole is broken to the core without any better alternative.

Politicians aren't incentivized to optimize for doing what's right for their constituencies or the greater good but instead they say whatever gets them (re)elected then do whatever their lobby friends who contribute to the party's fund tell them to do, while putting a positive spin on this for the great unwashed.

We have no system in place that holds politicians accountable for the damage they do throughout their careers.

Even when they are forced to resign due to various scandals, they often end up as "consultants" at the businesses they helped get rich with tax-payer money.

I don't disagree but how is that a feature of EU democracy and not democracy in general?

That statement can be applied to a lot of countries outside of the EU, it is not an EU specific problem. It represents a challenge for western democracies that appeared with the recent waves of populist movements (Trump, Brexit, 5 Stars, etc.)

Uninformed cynicism, however, is the exclusive mantra of online commentating.

The EU is disputing the report in question. And even if it were true, they'd probably have some reason than what you're coming up with in the absence of all information, which is basically "let's kill some people".

The point of this decision is that they think mRNA technology is the future, so they're investing in that. While I don't dispute that lots of EU politics is short sighted, this seems to be the direct opposite.
