You did not answer my question. Why does your wife regret getting the vax? Did she suffer from some malady because of it, or does she feel regretful because of all the crap you keep promoting to us here, about how bad the vaccine is, so if you took it, you were a fool?
Something you will NEVER know is if the vaccine saved her life. This is a complicated subject to muse, because of all the variables about body chemistry, sensitivity to virii, etc. The truth is, you will never know.
And of course, if your wife dies in a car accident, you will blame the vaccine, because the VAERS told you so.
