Countries from all over the world are in a kind of race for the first vaccine. While some of these vaccines are in the third phase of human trials, there are others that have just begun their human traces. People have been waiting for the vaccine for a long time, but according to the WHO, it is not possible to distribute the vaccine to everyone this early. WHO wants to promote the distribution of around two billion doses of COVID-19 vaccine by the end of 2021.
Even once approved, a vaccine must overcome many obstacles before it can be finally manufactured and placed on the market. The authority concerned also decides which particular generation it receives first. Second, the hardest part is to determine the cost. It should be economical enough for the Commons to buy, and it should also be profitable for the company that made it. True, there are some vaccines that are kept for the fourth phase. It is an on-going phase with regular studies being done to improve the effectiveness of the vaccines etc.
SARS-CoV-2 is the vaccine that is currently in the testing phase. Another vaccine production is Pfizer. The actual name of the vaccine is BNT162b2 and it is made by one of the largest pharmaceutical companies in the world from New York. The company manufactures the vaccine in cooperation with the German biotech company BioNTech.
There is one more vaccine in this race, Sputnik V. The vaccine is from Russia, and the third phase of the vaccine was found to be 92% efficient. There are several more vaccines, around 150, that are included in the study. We very much hope that the vaccines are ready and will be distributed soon.
