For example in Germany, politicians received a different type of flu vaccine, of higher quality, that was safer and caused fewer side effects. What makes you think that same thing cannot happen again?

There's actually competition for Covid Vaccines right now. Russia manufactures their own. So does China. Yet it's Pfizer (USA) that is in demand worldwide. So why wont it happen again? Because there's a race against time right now to end the pandemic, and to do so you need vaccines that are proven to work.

If the Elites somehow have a better version of this, then it's only an argument that vaccines work and we should be doing everything in our power to get a sample of this. But it's probably not necessary, since we have examples like Israel who are using "consumer ready" vaccines and are in the process of opening up.
