This vaccine uses the same new messenger RNA technology as two of the other vaccines in late-stage clinical trials: Moderna and Novavax. They are Genetic Vaccines that deliver one or more of the coronavirus’s own genes into our cells to provoke an immune response. They will hopefully have similar efficacy so we will have three vaccines available. The other vaccines are based on existing dead vaccines. Pfizer Vaccine gives us hope for the future!

Excerpts: “We’re waiting for the independent review. The peer-reviewed science work is still unknown to us. But, assuming all of this bears out, this is an extraordinary number. This vaccine will easily get into the Hall of Fame batting .900 percent, 90 percent.
It’s stunning, actually. When you think about it, the typical flu vaccine, its efficacy is somewhere between 40 and 60 percent. But there’s still a lot of work to do here, obviously. We’re talking, in all, of 94 cases among tens of thousands, 94 cases of COVID.
The Pfizer mRNA vaccines require storage of at least minus 80 degrees Celsius (minus 112 degrees Fahrenheit) until ready to be injected. That is colder than its competitors. This is creating a problem with what is called cold chain logistics.
It’s actually two shots, one, and then, a couple of weeks later, a second shot. So, getting people in for the first shot in a country where we have a lot of people who are suspicious of vaccines, that’s one thing, and then making sure they come back for the second shot, all those things have to happen in order for this to work.
Understandable analysis and interviews. Good animation of the vaccine and how it works. Video segments on manufacturing and distribution.
