I will not contribute to the Pfizer executive retirement fund any more. I took the two doses under protest, because my employer forced me to. But that's it.
Now, if the government forced Pfizer to produce and sell the vaccine at cost with the justification that there should be no profit from the pandemic, you could almost certainly bet that there would be zero push to take these endless boosters. In fact, I'm pretty sure they would be instead saying that only the people at highest risk level should take the vaccine.
