I am now vaccinated against yellow fever and never thought I would have to say that

Very soon, I'll be headed to Brazil with my wife, my oldest daughter, and my youngest son. We're looking forward to nearly a week in sunny Rio de Janeiro, home of the world-famous Christ the Redeemer statue as well as, apparently, various exotic tropical diseases.

Well, to be fair, there's really only one main disease they warn you about, and that's yellow fever. And even that is more of a thing if you venture into rural areas, rather than Rio itself.

Still, if you're going to Brazil, the U.S. Department of State and the Centers for Disease Control (CDC) make it pretty clear that you should consider being vaccinated against yellow fever.

Both entities take a decidedly passive-aggressive approach to this warning. Read what each has to say about traveling to Brazil and you walk away with a message along the lines of, "Look, you don't have to get the yellow fever vaccination, but if it were me..."

So we got it. All four of us.

Let me say two things about that:

• We had the vaccine administered at a place in Willoughby Hills, Ohio, very near our home. I found it on a list of approved yellow fever vaccination sites, but it was only after Elissa went that we learned it's less of a medical clinic and more of a beauty/wellness center that also happens to stock some vaccines. This was somewhat disconcerting.
  
  
• Guess how much the yellow fever vaccine costs. Go ahead, just take a guess...If you said $400, you were correct. Now guess whether anyone's insurance actually covers this cost. I will give you only one hint, which is that the answer is not, as I had hoped, "yes."
  

To that second point, the vaccination was just one of many unexpected costs and hassles we incurred getting ready for this trip.

Another was the Brazilian tourist visa, something that only just became a thing last month. If we had taken this trip in say, January, we would not have had to worry about it. But now travelers to Brazil have to apply for a visa.

The visa itself is $80 per person which, eh, isn't so bad, I guess. But the Brazilian government's frustratingly exacting standards when it comes to uploading your passport bio page, submitting a precisely edited and cropped head shot, and answering questions written by someone who likely did well in English classes at school but still lacks that real-world touch when it comes to getting across their true meaning, made the whole process more difficult than it should have been.

One good thing in all of this is that our travel itinerary and reservations were completed early on by Elissa, our oldest child and top-notch travel planner. At least that part of it hasn't been difficult.

What could be difficult, though, is getting back from this trip in one piece, given the list of other diseases besides yellow fever the State Department says can sometimes be found in Brazil. Those include chagas, chikungunya, dengue, zika, leishmaniasis, rabies, tuberculosis, schistosomiasis, and the always-festive traveler's diarrhea.

Why didn't they just throw cholera. diphtheria, beriberi, rickets and the vapors in there to complete the cavalcade of 19th-century maladies we could theoretically contract?

Despite all of that, though, I'm very excited to go. It's going to be like the Oregon Trail of international vacations.
