In recent days, the question is often heard why so few pharmaceutical companies are engaged in the production of vaccines. The following tweets are the source of these questions:

All this is great, but far from the idyll outlined in the tweet at the beginning of the article. There are no "dozens of companies that are ready" to produce vaccines and "end the pandemic." In fact, these are the same few big players that everyone already knows about - they do not sit idly by. To assert the opposite is fiction, but we operate with facts.
