The problem is that at this moment, you cannot be sure of that being the purpose of it(in all likelihood that's not it.) Personally speaking, I believe that a lot of what you are seeing for arguments coming from the anti vaccine front relies too much on misunderstandings about what vaccines actually are/recycled fears instead of looking at the actual data/experimental nature of it. At any rate, I think once this is all over you will see that the vaccine is likely overhyped/it's main purpose was more or less to make Pfizer and their ilk a shit ton of money instead of relying on more natural means to treat the virus(or alternatively a means for good pr.)
