So, as I have stated, taking the vax which contains the remnants of an aborted baby has nothing remote material about it. It’s a formal and direct participation in an ongoing evil. This is the argument of Fr. Ripperger and others. I too concluded this independently without having read about their position first.
As for vaxxes tested with aborted babies, the crime of abortion and the abortion industry is so heinous, that one cannot find a proportional reason that would make it licit. This is in fact the argument of +Vigano and +Schneider, and accepted by -+Williamson.
