travelers be up to date on routine vaccines, including measles, mumps, rubella (MMR) and varicella (chickenpox).
In general, try to schedule vaccinations at least four weeks before travel.
Another important point: Stock up on your current prescription drugs and certain over-the-counter (OTC) medications before you leave. In terms of OTC products, Walker strongly recommends medications for indigestion, pain drugs like Tylenol (acetaminophen) or Aleve (naproxen), antibiotic ointment, bandages for minor cuts or blisters, sunblock and insect repellent.
