State officials say problems that have prevented many Mississippians from scheduling their coronavirus vaccinations are being worked out. On Tuesday, after Governor Reeves announced that people 65 and older and those 18 and up with pre-existing medical conditions could start making appointments to get shots, the state's COVID-19 hotline and the online registration system were both overwhelmed. And on Wednesday, the website was still showing thousands of people waiting to get through to make appointments. Mississippi Emergency Management director Greg Michel says the University of Mississippi Medical Center's website was designed to handle only 5000 users at a time-- and it's being upgraded to increase its capacity. Michel says the call center will soon be able to answer four times the calls. He's expecting both fixes to be completed in the next 24-48 hours.
