The difference between the “Moderna” and “Pfizer” vaccine?

With the American company “Moderna” announcing the success of its new vaccine in its latest clinical trials, attention began to turn towards this new achievement, which comes days after a similar announcement from the American company “Pfizer” and the German company “Biontech. “.

From a scientific point of view, the two vaccines have a very similar mechanism of action, while the two differ from the predominant patterns followed by the usual vaccines.

It used to be that the vaccine consisted mainly of weak or inactivated viruses or parts of the virus that do not cause disease to the body, but only inform you of the disease, stimulate you to produce antibodies that remain inside you for life and defend you against it viruses in the future.

As for the “Modern” vaccine, it takes a different approach, as it consists of small pieces of DNA “mRNA” that stimulate the body to produce the protein on the surface of the emerging corona virus.

It is this protein, which gives the Corona virus its distinctive coronavirus form, that helps the microorganism adhere to human cells in the early stages of the disease.

Once this foreign protein is produced in the body, the immune system senses the presence of the virus and begins to produce the antibody, as if the person is already sick.

This method is similar to the way the recently announced Pfizer and Biontech vaccines work.

Both vaccines require two injections, several weeks apart.

And Moderna announced Monday that its vaccine provides strong protection and gives a glimmer of hope in a grim situation following the high number of infections with the Coronavirus in the United States and around the world.

The company stated that its vaccine appears to be 94.5 percent effective, based on preliminary data that was based on a company study that is still ongoing.

Moderna expects to receive around 20 million doses destined for the United States by the end of 2020, while Pfizer and its German partner expect to receive around 50 million doses worldwide by the end of the year.
