Random thought coming . . .
Do we need shots for this cruise?
not
We NEED the latter, I'm worried about the former.
Remeber kids, malaria is not a good souvenir.
The US CDC has a great traveler's health website
http://www.cdc.gov/travel/
You can use it to build a personalized copy of the Yellow Book and create a table based on the countries you're visiting.
Accordingly, yellow fever vaccines are not
required by Columbia or Mexico. Yellow fever vaccines ARE required by Aruba "If traveling from an endemic zone and >6 months of age" and Bahamas "If traveling from an endemic zone and >1 year of age" but for our purposes, they aren't needed.
CDC yellow fever vaccination recommendation for Columbia: "Recommended for all travelers >9 months of age. Travelers whose itinerary is limited to the cities of Bogotá, Cali, or Medellín are at lower risk and may consider foregoing vaccination."
As for malaia....
Columbia
"Risk in all rural areas at altitudes <800m (<2,624ft). No risk in Bogotá and vicinity."
Mexico
"Risk in rural areas, including resorts in rural areas of the following states: Campeche, Chiapas, Guerrero, Michoacán, Nayarit, Oaxaca, Quintana Roo, Sinaloa, and Tabasco. In addition, risk exists in the state of Jalisco (in its mountainous northern area only). Risk also exists in an area between 24°N and 28°N latitude, and 106°W and 110°W longitude, which lies in parts of Sonora, Chihuahua, and Durango.
No malaria risk exists along the United States-Mexico border. No malaria risk exists in the major resorts along the Pacific and Gulf coasts."
