COVID Herd Immunity Not Close

COVID cases are surging, even among people vaccinated, but public health experts say we’re not close to achieving herd immunity. Dr. John Carlo with the Texas Medical Association says this virus is constantly changing. He says each version of COVID is slightly different, so even if we reach herd immunity to Omicron, there will likely be another variant around the corner. And there is so much global travel it’s hard to keep COVID contained.
