Dr. Anthony Fauci isn't 'particularly concerned' about the safety of Moderna coronavirus vaccine

• White House coronavirus advisor Dr. Anthony Fauci said Monday he is "not particularly concerned" about the safety risk of a potential coronavirus vaccine by Moderna, despite the fact that it uses new technology to fight the virus. 
• The vaccine, which entered a large phase-three human trial Monday, uses messenger ribonucleic acid, or mRNA molecules, to provoke an immune response to fight the virus. While early studies show promise, mRNA technology has never been used to make a successful vaccine before.
• "I'm not particularly concerned," Fauci said. "But I don't want a lack of severe concern to get in the way that we are keeping an open mind to look for any possible deleterious effects as we get into and through the phase-three trial."

White House coronavirus advisor Dr. Anthony Fauci said Monday he is "not particularly concerned" about the safety risk of a potential coronavirus vaccine by Moderna, despite the fact that it uses new technology to fight the virus. 

The vaccine, which entered a large phase-three human trial Monday, uses messenger ribonucleic acid, or mRNA molecules, to provoke an immune response to fight the virus. Scientists hope mRNA, which relays genetic instructions from DNA, can be used to train the immune system to recognize and destroy the virus. While early studies show promise, mRNA technology has never been used to make a successful vaccine before.
