Sorry pal, but the most you can probably do action wise, would be to just take some rest and ride it out when those symptoms hit. Taking paracetamol can help to offest some of the vaccine side effects such as pyrexia, chills, bodyache etc. If mentioned this elsewhere on this forum, but one way of looking at it, is that it's your immune system kicking in for a fry and gearing up itself should the real deal strike.
