The first vaccine against Covid 19 is released.

According to clinical trials it offers protection up to 90%.

The American company “Pfizer” and the German “BioNTech” have made possible for the first time the efficient production of an anti-covid vaccine.

Their vaccine has been tested on 43,500 people in six countries around the world and has had no side effects.

Companies plan to apply for emergency vaccine approval by the end of the month. Currently, there are dozens of vaccines that have reached the final stages of testing, but this is the first to show results.

Two doses will have to be applied, with a time difference of three weeks and according to pharmaceutical companies, people will be protected one week after the second dose.

The vaccine has been tested in the United States, Germany, Brazil, Argentina, South Africa and Turkey. Pfizer believes it will be able to deliver 50 million doses by the end of this year and about 1.3 billion by the end of 2021. According to the New York Times, this is a big day for science and humanity.
