Yep its very possible that these corporations want to get the vaccinations out as fast as possible because every day it is late, they will be making less money. The vaccines have not been approved by fda, which means they have not been thoroughly tested and examined by the fda. They have gotten emergency use authorization which only means some political process have authorized it. When you look at data, don’t forget that so many times in history data has been cooked to achieve profits. Even pfizer has paid over 5 billions in fine because they have put out medicines without thorough testing, which were in fact approved by fda. So forget about approved medicines, this ones not even been approved so one has to really believe blindly in the system to accept this as an effective solution.
