The world is thirsty for any positive developments that may herald the dissipation of the dreaded virus clouds, so it is not surprising that everyone dances with joy that Pfizer and Biontech announced that the effectiveness of their potential vaccine for the Corona epidemic exceeds 90%.

A great day for science and humanity, this is what it looked like last Monday, as Albert Polar, CEO of the American company Pfizer, announced that the joint vaccine with the German company achieved impressive results and at the same time is rushing to sell his personal shares !!

And soon the positive news of the vaccine was reflected in the markets, with the value of the MSCI Global Stocks Index jumping by about $ 1.8 trillion, as all stock exchanges soared and the American Dow Jones jumped to reach a new historical level above the 30 Not only that, but investment banks rushed to raise their expectations for stocks, as Goldman Sachs believes that the Standard & Poor's Index will rise 21% next year to a record level of 4,300 points.

Perhaps it is an American electoral paradox that last Monday was important on the road to the vaccine, when Pfizer and Biont announced that the results of the last phase of clinical trials showed that the vaccine protects against the Corona virus by more than 90% after seven days of the dose The second, on the same day, President-elect Biden announces his plan and his council to combat the epidemic.

Corona virus is no longer Chinese, but has become American par excellence, to top the global scene, with more than 10.7 million infections and 247,000 deaths so far, so the infection prevention rate is a great victory in the battle against the epidemic that has killed 1.2 million people Around the world, as it exceeds most expectations about the effectiveness of between 50 and 60% for any other vaccine, but in order not to be overly optimistic about commercial advertisements that aim to achieve billions first !!, we must know that the percentage of vaccine effectiveness may vary with the continued collection Safety data Although the American company has not disclosed any side effects so far, but there are some sources that indicated the presence of these symptoms
