OAKLAND PARK, Fla. – A senior medical center in Oakland Park kicked off an effort to vaccinate more than 1,000 seniors with the two dose Pfizer vaccine Saturday. Chen Senior Medical Center in Oakland Park and as their location in Miami are vaccinating people 65 and older who had pre-scheduled appointments. The urgency to get more people vaccinated against COVID-19 comes on the heels of University of Miami researchers announcing that they have detected variants across Miami-Dade County. “We’ve turned up three variants originating from Brazil,” said Dr. David Andrews of the University of Miami Miller School of Medicine. The three Brazil variants are in addition to the UK variant and now a newly found New York variant.
