Will two lots of vacinations make my ds sick?

[yogamat]

Don't ask me why but I let someone put me off having the 16 week injections after he'd had the 8 and 12. Chemical overload stuff. Anyway I now regret that and planned to take him for them tomorrow even though he is now 32 weeks.
But I also need to get him a BCG asap as we are travelling overseas for a hol in a TB effected area in six weeks. Not out of choice but have to for family reasons.
So my question is: can he have both in one week? Or is that too much for a little body to handle?
On top of this he has a cold poor wee thing so I'm dreading making him feel even more unwell.
Any thoughts?
BCG takes eight weeks to be fully effective so we are already running late with that but should I postpone the others for a week or two?

I think I might hesitate. Vaccines cause a drop in immune response for several weeks which isn;t what you want jetting off on holiday.
Dunno whether the BCG is live or not.
