US Set to Make Decision on COVID Booster Shots 

The next couple of weeks will tell whether the U.S. will begin to offer coronavirus booster shots to its population, Dr. Francis Collins, the director of the National Institutes of Health, told the television show “Fox News Sunday.”  

“There is a concern that the vaccine may start to wane in its effectiveness,” Collins said.    Healthcare workers, nursing home residents and other older people would be the first in line to receive the booster shots, according to the NIH director.   The delta strain of the coronavirus is driving up the COVID caseload in the U.S. to approximately 129,000 new infections a day, a 700% increase from the beginning of July. Collins said the case load could jump to as many as 200,000 a day, rivaling the worst days of the COVID outbreak in January and February.
