it's a difficult one to judge because different musicians will use their arms in different ways, and also practise differently: the advice is to avoid heavy muscular activity for forty eight hours after vaccination, as is the case for the seasonal flu vaccine too. The heaviest job I have is playing contrabass recorder, because that involves holding arms up and away from the body for prolonged periods of time - I hadn't then got my beautiful bass

recorder, but would have found that a challenge to hold for a long time too, though the sling makes it easier. I succeeded in forgetting to take the contrabass to orchestra

, and had no problems with any of the smaller instrumemts.
When practising, I only play in relatively short bursts, no more than an hour or so, so would have been fine even to do my diploma with the vaccine on board....but I know I would also have deferred it so close to the exam, had the whole situation arisen last year. That means I can't advise properly one way or the other - you really have to be guided by "how much of it there is around" where you live, and whether you know people who have had it...and even really if you use lots of public transport and might be exposed to it that way. The trouble is, you'd find it difficult to do a diploma if suffering from swine flu too...
That's how I felt really, if I turned it down, sods law I'd get the full blown version for my diploma instead as I spend my days teaching in schools!
I got much worse aches from my yearly flu jab this year, just one of those things, didn't last long but holding my violin to teach, and especially being in a cold practice room at school all day didn't help!
Practising for an hour at all would be luxury at the moment, sooo busy!
