So, Europe is left out of the massive purchase of this injectable, for which countries such as the Netherlands, Germany, Italy and France, those belonging to the Inclusive Vaccine Alliance, have already negotiated.

It was last June when the British pharmacist AstraZeneca announced that it has signed a 400 million doses with several member states of the European Union to supply them with their potential coronavirus vaccine.

Spanish vaccine?

The Minister of Science and Innovation, Pedro Duque, has affirmed this Thursday that he is “much more optimistic” than three or four weeks ago about the availability of the Spanish prototypes of the vaccine against Covid-19, and considered “quite possible” that Vaccine tests are carried out in Spain “shortly”, possibly before the end of the year.

These statements come after it was learned that some of the Spanish prototypes of the vaccine are now immersed in animal experiments and, if the results are positive, several groups could ask the Spanish Medicines Agency in December for permission to start the human clinical trials.

Once this permission was obtained, which could take weeks or months, the first phase of these trials with healthy volunteers would begin.
