Well maybe you guys are one of the rare sufferers of actual side effects/allergies and shouldn't get the vaccine, assuming any of the above is related to the vaccine and there weren't other medical issues going on. Or if there were maybe said medical issues interact negatively with the vaccine and should be accounted for.
That said all vaccines have side effects for some populations. There a reason why when you get your flu shot they ask you if you've had any previous bad reactions to flu shots. That doesn't make the flu shot or any vaccine a bad bet, sometimes you bet with 99% odds and end up the 1%.
