I see
Well, I think that theoretically be a connection with the vaccine although it seems unlikely and we shall probably never know for sure. In terms of future vaccines I would say the following:-
1) If the problem was a reaction of the immune system to the vaccine, then there is no reason to think that a different vaccine would have the same effect as it would stimulate the immune system in a different way.
2) If it was a general reaction to having a shot / pain etc then of course this could happen again but is not dangerous.
3) Practically I would advise you mention this before any future vaccines so that the treating physician can have it on record. I would also advise seeing a child neurologist (if possible, one specializing in movement disorders) and i would assume they would want to investigate the issues on the assumption they are not connected to the vaccine..it may be worth testing the ASO levels even now and it will be important to describe any similar issues in the family....not just tics but also OCD, ADHD, other movement issues and Tourette's.
Hope that helps and keep us updated.
Most importantly, I wish your son better!
