I'd rather get patch vaccines before my trips, I'm too familiar with getting needle vaccine and experiencing what is outlined below. Not to say patch would eliminate all, however I think slow release and not a quick injection straight into a vein would have an effect.

86% of the volunteers that received Novartis’s H1N1 vaccine reported adverse reactions after one or both doses – the most common local side effect experienced was injection site pain. The reactions were generally mild or moderate and resolved after 72 hours. Reported local adverse events, or side effects occurring at the location where either vaccine had been administered, include the following:

Tenderness
Pain
Redness
