No Vaccinations are currently required for visiting Peru. A yellow fever vaccination is recommended for those visiting the Amazon Jungle. This vaccination, which is valid for 10 years, must be administered at least 10 days before your arrival in Peru. However, those who are only visiting the highlands have no need for this vaccination.
Malaria preventives are NOT recommended as they often have disturbing mind-altering and physical effects. These days, malaria is extremely rare and treated with the same medication used to prevent it.
