It's unlikely. As the pp says, when you test a medication (I do this as part of my job) you have record everything, literally everything that occurs after taking it.
So for example, let's say a patient is in one of our trials, is crossing the road and gets hit by a car. They end up with a broken leg. That gets listed as an adverse event, albeit designated as not related to the drug. That's a really extreme example of course, but any coughs, colds, puking etc, it all gets listed as an adverse event. You can only say it's definitely not related if you have a certain degree of evidence, so loads of stuff that is totally unrelated ends up in your (terrifyingly long) list of side effects.
Interestingly, if you inject people with saline solution as a placebo, roughly the same number (a couple of percent) report vomiting etc.
The most common 'real' reaction is a sore arm, redness at site and a slight rise in temperature as your immune system goes to work. People sometimes feel a bit off for a day or so.
I'd call your go just to let them know - you may have one of the glorious vomit bugs going round right now.
