If I am playing Devils Advocate and pretending I supported this conspiracy theory, then my response would simply be “because they caught covid”.

Now if you were to follow up with “how come the test was negative”? my response would be “I believe that the government is lying about the vaccines being real, do you really think I believe the tests work accurately”?

*I don’t actually believe this. I just think it would have been the easiest conspiracy theory for anti-vaxxers to run with.
