Cooper tweeted that North Carolina received its first limited supply of Pfizer vaccines shortly after 9:30 a.m. According to WFMY in Greensboro, North Carolina, Wake Forest Baptist Medical Center was among the first locations in the state to get the vaccine.

“The first doses of COVID-19 vaccine have arrived in North Carolina,” Cooper tweeted. “It’s a limited supply for now, but this is a remarkable achievement for science and health. We all need to keep wearing a mask and acting responsibly while we get as many people vaccinated as fast as we can.” #COVID19 #Coronavirus
