We are witnessing some weaknesses in terms of the production capacity of Covid-19 vaccines. Investments must be made in this direction, European Commissioner for Innovation, Culture, Education and Youth Mariya Gabriel told BNR's Horizont channel. 

Regarding vaccination imbalances in the EU countries, Commissioner Gabriel said it was the responsibility of the Member States themselves. "The European Commission has fulfilled its obligation to deliver the vaccines to all EU countries at the same time. It is also important to provide information constantly, because we have been witnessing vaccine distrust", Mariya Gabriel added. “There are such discussions, but in my view, we should wait and approach the issue very carefully”, Commissioner Gabriel said in response to the question whether the Covid-19 vaccine could become a visa to enter a European country.
