With a huge core of college students and faculty members heading off to destinations in Central and South America, Asia, Africa and other hot spots in the developing world, Boulder has a lot of international travelers who require travel immunizations.

That means the staff at the Boulder travel immunization business, Passport Health Colorado, are very busy this time of year with students, faculty members and other travelers scheduling their immunizations ahead of spring and summer travel plans.

"Despite the growing wave of international travelers from Boulder to the developing world, there is still a lot of confusion about what immunizations are needed," said Michelle Reesman, RN, executive director with Passport Health Colorado. "The confusion centers around the issue of what's 'required' versus what's 'recommended.'"

Reesman said countries "require" shots for diseases they believe will put their residents at risk. Meanwhile, The CDC and World Health Organization (WHO) "recommend" the immunizations the organizations believe are necessary to ensure travelers stays healthy. "Budget travelers who opt for only what's 'required' are often putting themselves at serious risk of disease," Reesman said.

You never have to look far to find dangerous disease outbreaks in the developing world. For example, Paraguay is in the midst of a serious Yellow Fever outbreak and Brazil is also battling this mosquito-borne illness. Reesman said that it's fortunate Yellow Fever vaccine stocks, very recently in short supply, are finally starting to be replenished. Because Passport Health Colorado provides a high volume of Yellow Fever vaccinations, it is one of the first vaccinators to receive this critical medicine.
