Apart from the usual vaccinations for UK, there are some recommended vaccines for Turkey. Which vaccines you will be recommended depends on where you are staying and what you are doing.
Hepatitis A vaccine is recommended for all visitors to Turkey, and typhoid for those who are travelling away from areas where clean food preparation can be guaranteed. Contact your GP, who will ask you for details about where you are staying and what you plan to do on your holiday. If, like us, you are sticking to well-known holiday resorts, it is likely that you will only be recommended to have Hap A vaccine.
If you get your Hep A sorted out now, you have a first injection, and a second between 6 and 12 months after that. This will last 20 years according to my vaccination card. Keep Tetanus vaccination up to date as well, this is often given as a triple jab including Diphtheria and Polio, lasting 10 years. Typhoid may be offered as well which lasts 3 years.
Our GP surgery did all our injections free of charge but this may not be the case everywhere.
