The new mRNA vaccines target the KP. 2 variant because most recent covid cases are caused by that strain or closely related ones. The Novavax vaccine targets the JN. 1 variant that recent variants ...

While the new, approved COVID-19 vaccines are the first mRNA vaccines to be licensed by the FDA, the technology has been in use for cancer research since at least 2011.

The new updated Comirnaty Pfizer COVID mRNA vaccine is seen here next to the Fluzone H,D. influenza vaccine at a Walgreens pharmacy in Torrance, Caifornia, on September 5, 2024.

With significant refinement, mRNA vaccines could treat not just viral diseases like COVID-19, but inherited diseases, allergies or even cancer.

The story of mRNA vaccines dates back to the early 1990s, when Hungarian-born researcher Katalin Kariko of the University of Pennsylvania started testing mRNA technology as a form of gene therapy.

For many Americans, the arrival of COVID-19 vaccines less than a year after the pandemic began is, quite literally, unbelievable. That skepticism, in turn, is contributing to hesitancy to get the shot ...

They then create a single mRNA that triggers the body to make these proteins – just as COVID-19 vaccines trigger production of the spike protein that sits on the surface of the virus.

With this backdrop, we believe that COVID-19 survivors should only get one dose of mRNA vaccine (made by Pfizer and Moderna) which would speed the rate of immunization by allowing others to get ...
