Everyone should make sure they are up-to-date on all recommended vaccinations. You can check out the most recent information provided for the region by looking at the web site of the Centers for Disease Control, (https://wwwnc.cdc.gov/travel/destinations/traveler/none/peru). Standard immunizations include: yellow fever, typhoid, influenza, tetanus, and hepatitis A and B. Chloroquine or other malaria prophylaxis is optional, though a US or European physician is likely to insist that you take prophylaxis as a precaution. We have not yet had a malaria case at the Station.
