Traducerea - Turcă-Engleză - Çocuklara kızamık aşısı sonyıllarda 12. ayda...

Hi kfeto,
This would read better if:

"For the last couple of years the measles vaccination for children has started in the 12th month of life (of age).

Hi Kfeto,

I think your translation is correct, but the verb should be "to start". --> has started to be made/performed, or sth like that

I think "has started being administered" would be the best choice.
