Oh yeah, it is absolutely true that Big Pharma makes next to nothing for vaccines. Also there are methods for making vaccines that don't rely on eggs for example that are way way faster, but these methods are also way more expensive so Big Pharma sticks with the ancient method of chicken eggs even though it is way slow.

Governments absolutely need to pressure Big Pharma to use the newer methods to make vaccines or else when the really bad flu comes one day, we will be totally screwed if the vaccine rollout takes as long as it is taking now.
