Years of research laid the groundwork for speedy COVID-19 shots

The Nobel Prize in Medicine has been awarded to two scientists whose work led to mRNA vaccines against COVID-19

The Nobel Prize in Medicine was awarded Monday to two scientists whose work led to the mRNA vaccines against COVID-19.

As countries prepared to roll out those shots, The Associated Press took a look at how the vaccines were developed so quickly. Below follows the original story, first published on Dec. 7, 2020.

How could scientists race out COVID-19 vaccines so fast without cutting corners? A head start helped — over a decade of behind-the-scenes research that had new vaccine technology poised for a challenge just as the coronavirus erupted.

“The speed is a reflection of years of work that went before,” Dr. Anthony Fauci, the top U.S. infectious disease expert, told The Associated Press. “That’s what the public has to understand.”

Creating vaccines and having results from rigorous studies less than a year after the world discovered a never-before-seen disease is incredible, cutting years off normal development. But the two U.S. frontrunners are made in a way that promises speedier development may become the norm — especially if they prove to work long-term as well as early testing suggests.

“Abject giddiness,” is how Dr. C. Buddy Creech, a Vanderbilt University vaccine expert, described scientists’ reactions when separate studies showed the two candidates were about 95% effective.

“I think we enter into a golden age of vaccinology by having these types of new technologies,” Creech said at a briefing of the Infectious Diseases Society of America.

Both shots — one made by Pfizer and BioNTech, the other by Moderna and the National Institutes of Health — are so-called messenger RNA, or mRNA, vaccines, a
