It’s probably safer to be vaccinated while travelling, 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.
Food or water may contain bacteria or germs which our body are not always able to overcome. Remember that what is normal for Peruvians is not always normal for others and it can cause many health complications. Definitely 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 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 am feeling healthy. (Although I have had some small stomach problems a couple times.)
The most habitual vaccines recommended to travel to Peru, listed below:
- Hepatitis A and Hepatitis B
- Yellow Fever
However you need to remember, that before a trip you should always check the actual information about doctor’s recommendations in the case of vaccines.
Below you will find some websites on which you will find actual information about vaccines recommnded in Peru and in other countries.
Remember also that you should think about vaccines at least some weeks in advance, if not months. Some of the vaccines are given in sets of 2 or 3 shots with longer breaks. If you plan a trip for more than some months, you need to start the whole process of vaccination much earlier.
If you have any health problems, it is always necessary to check if you can take vaccines. You need to talk about that with your doctor.
