Personally, I think you have to be vaccinated, even if the vaccinations in the country which you are planning to visit are only recommended, not mandatory. I know some people who travel to Peru without vaccination and have no problems, but I also know those who, due to the lack of vaccination, have had health complications.
When planning a trip to Peru, you need to remember that the conditions prevailing here often differ from the standards that you are familiar with in your home country.
Food or water may contain bacteria and germs which your body may not be able to overcome. Remember that what is normal for Peruvians may not be normal for you and for foreigners in general. This can cause health complications.
You must watch what and where you are eating. In Peru water is not the cleanest, so you have to avoid contact with tap water.
As for the food, if you want to eat cheap or very cheap, you have to be aware of the risks associated with it, but if you are careful, you should not have problems. For example, I eat in typical, low-cost Peruvian restaurants and I have never had any serious complications other than some small stomach problems.
The most common vaccines needed to travel to Peru are listed below:
- Hepatitis A and Hepatitis B
- Yellow Fever
Remember to check the actual information about recommended vaccines prior to your trip.
Here are some websites where you can find information about vaccines recommended in Peru and in other countries.
Remember also that you should think about vaccines at least some weeks in advance, or even some months. Some of the vaccines are given in 2 or 3 shots in a longer breaks.
If you have any health problems, it is always necessary to check if you can take vaccines. Consult your doctor ahead of time before you leave.
