Pfizer and BioNTech claim that the corona vaccine they discovered is able to protect 90 percent of people from the coronavirus. However, their claim is based on tests performed on only 94 people.
.
The vaccine has been administered to 43,000 people in eight countries. The full result has not come yet. Only when the complete results are verified and those results are verified can the real effectiveness of the vaccine be known.
.
Although the vaccine has proven effective, it will take many months to produce it in large quantities and spread it around the world. The company says it will be able to produce 1.3 billion doses by the end of next year.
.
It is worth mentioning here that this vaccine has shown 90 percent effectiveness after giving two doses to each person. So by the end of 2021, if 1.3 billion doses are made, half of the people will be able to take it.
.
There are still many challenges though. But it is promising news.
Please, you take the vaccine first.
