If I'm going to experience world travel, there's a whole lot of shots I have to get. And it's not that I'm afraid of the needles. It's my fear that vaccines could be somewhat damaging to my long-term health. Having got hit with Chronic Fatigue Syndrome in my teens shortly after having a Polio vaccination, I have had a hard time shaking the idea that the two may have been connected, even though there is much scientific research to dispel any connection.
I have done a fair amount of research on the vaccination issue and feel that while vaccinations are generally safe, there are risks involved. So, I'm going to book myself an appointment with a travel doctor and learn all I can about the vaccinations I'd require to travel abroad, the benefits and the risks. All said and done, I am of the opinion that there are always risks involved in any choice and I can't keep myself back from fully experiencing my life just because of the potential risks.
Sometimes though, I wish life and its choices weren't such a constant cost/benefit, not to mention, existential and soul-searching, analysis. No one said the examined life was easy.
