ST. LOUIS (KMOX) -- Pharmaceutical giant Pfizer says its Chesterfield campus is one of only three U.S. plants to play a part in manufacturing the Covid-19 vaccine.
Suburban St. Louis is where all of the raw material will originiate.
Robert Langreth of the Bloomberg Health Team says Pfizer's facility here will have to make a lot of that raw vaccine material.
"I think they're hoping to have as many as 1.3 billion doses by the end of 2021. That's around the world. Do the math: it's a two-dose vaccine, so that might be enough for 650 million people."
Once the plasmid DNA is manufactured in St. Louis, it goes to Andover, Massachusetts, where the template DNA is incubated with the mRNA building blocks to create the substance of the drug, which then goes to Kalamazoo Michigan to be combined with other ingredients and filled into vials.
Langreth says other vaccines which are close behind Pfizer's work the same way.
We've previously told you about a potential vaccine for further down the road, developed at Washington University School of Medicine. The nasal spray appears to provide immunity from Covid-19 in the upper respiratory tract.
