ABC7 Chicago s Mark Rivera walks you through how to use the COVID-19 vaccine calculator to find your place in line to get the shot. I did receive the vaccination this morning, I do feel great, Dr. Tamara Chambers, chief medical director at L.A. County-USC Medical Center, said during an online briefing. I m so grateful that I ll be able to continue to provide safe and effective care to patients - particularly in the critical-care and the ICUs during their most dire times of need, Chambers said, and that soon we ll be able to move it out to the communities so that we can get rid of this pandemic forever.
