Regarding meningitis:
"About 2,600 people get meningococcal disease each year in the U.S. 10 to 5 percent of these people die, in spite of treatment with antibiotics. Of those who live, another 11to19 percent lose their arms or legs, become deaf, have problems with their nervous systems, become mentally retarded, or suffer seizures or strokes.
Anyone can get meningococcal disease. But it is most common in infants less than one year of age and people with certain medical conditions, such as lack of a spleen. College freshmen who live in dormitories have an increased risk of getting meningococcal disease.
Who should get meningococcal vaccine and when?
Menactra is recommended for all children at their routine preadolescent visit (11 to 12 years of age). For those who have never gotten Menactra previously, a dose is recommended at high school entry."
While the CDC specifically recommends vaccination if you are visiting the "meningitis belt" in Africa, it certainly does not give the impression that it would be overcautious otherwise. In fact the CDC says the following regarding the vaccine:
"Meningococcal conjugate vaccine (MCV4) is routinely recommended for all 11 through 18 year olds. If your child did not get this vaccine at their 11 or 12 year old check-up, make an appointment for him or her to get it now. "
Regarding Japanese Encephalitis:
"Q. What is the mortality rate of Japanese encephalitis?
A. Case-fatality rates range from 0.3% to 60%.
Q. How many cases of Japanese encephalitis occur in the world and the U.S.?
A. Japanese encephalitis is the leading cause of viral encephalitis in Asia with 30-50,000 cases reported annually. Fewer than 1 case/year is reported in U.S. civilians and military personnel traveling to and living in Asia. Rare outbreaks in U.S. territories in Western Pacific have occurred.
Q. How is Japanese encephalitis treated?
A. There is no specific therapy. Intensive supportive therapy is indicated."
That is from the CDC website - while true it is very rare in travelers, it isnt all that rare if up to 50,000 people get it every year. No treatment exists, and you have up to a 60% fatality rate.
While somewhat expensive I felt that these vaccinations were worth the money. True there are plenty of diseases that you cant prevent like Dengue, which I did get in Costa Rica, but I experienced some peace of mind after my immunizations. Although I don't find it absolutely necessary even the rabies vaccine was worth it, I wasnt afraid to go caving or walk past the packs of street dogs you see in almost every third world country. If I got bit I felt confident that I would have enough time to get treatment. Hard to put a price on that.
