Health Department says online vaccine registration process has improved By Susan DeVilder The Star Courier Health officials say progress in vaccinating seniors, healthcare workers and essential workers has made it easier for residents to register online for a clinic appointment. On Monday, the Henry & Stark County Health Departments opened up registration on its website for the county’s latest mass vax clinic shortly after 8 a.m. But rather than being snatched up in a matter of minutes, the vaccine time slots remained open for several hours. But the availability of those appointment times isn’t due to a decrease in demand for the vaccine, said Rae Ann Tucker, director of health promotions for the HSCHD.
