I had the injections the first time I visited Side in Turkey on the Doctors recomendation,but this was nearly 16 years ago.
It does depend on the area you are going to visit and The
Marmaris area is one of the places were injections arent necessary.
Holiday brochures dont insist you have injections.
Its the same old story though if injections give you the peace of mind have them done.
