I received my very first flu shot yesterday; if I had known that it was that easy, I would have had them every year! Nothing spoils a person’s fun more than being sick. Being sick when you are a long way from home is more miserable.
Of course, you need to check with your family doctor to see if possible health problems or allergies would indicate that this is not appropriate for you. If you are cleared for getting the shot, ask how many days before you travel would be the best time to receive it.
