President of European Commission Ursula von der Leyen tweeted "Vaccination is gathering pace across the EU: we have just passed the 150 million mark.”

Combined with photos of European citizens vaccinated against the deadly virus, Ursula von der Leyen stated "a quarter of [adult] Europeans have already had their first dose".

"We will have enough doses to vaccinate 70% of adults by July”, which is the official target of the European - by the end of summer, 70% of European adults are to be immunised with the vaccine.

The four vaccines currently approved in the EU: Comirnaty (the other name of Pfizer/BioNTech vaccine), Moderna, Vaxzevria (the new name of AstraZeneca's vaccine), and Janssen (Johnson & Johnson's vaccine).

The European Centre for Disease Prevention and Control (ECDC) conveys that an average of 10.5% of the EU population is fully inoculated (with both doses of the covid-19 vaccine), while 28.1% received the first dose.

The news of vaccinating a quarter of EU citizens follows the struggle the European Union initially had, concerning the AstraZeneca/Oxford vaccine.

The constant delays in vaccine delivery and doses by the pharmaceutical company AstraZeneca are due to contractual disagreements, and regulation in terms of rare blood clots. There are also rare blood clots noted with the Janssen vaccine, but both vaccines are approved to be safe, with the benefits outweighing the negatives.
