With the COVID vaccine in high demand, some experts had suggested that the US release the second dose supply to get more people inoculated but not so fast says, Doctor Fauci.

It’s too risky to go to giving a single dose of coronavirus vaccine to stretch out the supply, Dr. Anthony Fauci said Friday, even after reading an Israeli report that seemed to show that a single dose could provide up to 85% protection even four weeks later.

“We will stick with the scientifically documented efficacy and optimal response of a prime followed by a boost with the mRNA vaccines,” Fauci, who is director of the National Institute of Allergy and Infectious Diseases, told a White House briefing. “The reason is even though you can get a fair degree of, quote, protection after a single dose, it clearly is not durable,” he added.
Fauci said it takes two doses of the Moderna and Pfizer/BioNTech vaccines to get full immunity to coronavirus infection.
