On restrictions and measures taken against the coronavirus, he said: "The fluctuating appearance of the [COVID-19] strains necessarily make it difficult for us to make decisions."
He also said the country would continue to ease coronavirus restrictions but added the priority remains the "well-being of our citizens."
On other vaccine purchases, Erdoğan said Turkey's agreements with China and Germany are ongoing, adding that there are ongoing talks with Russia towards an agreement.
