Maybe it's a question of different reactions on different people, differences that aren't paid attention to by who "engeneers" the vaccine (and that would be difficult to spot too). Because I had no problem with, say, the tetanus shot, or the HepaB one (and the paperwork I had to sign to get the latter, oh,
that paperwork!).
Then again, there should be a way to get the two birds (vaccine and not-disastrous follow-ups) with one stones even with people like us who have a bad reaction, we're more not few
