Governor Mike Parson announced all COVID-19 mass vaccination events are being canceled this week in the interest of safety due to extreme winter weather. The Randolph County Health Department announced this includes the second dose vaccination scheduled for this Friday. A makeup date hasn’t been announced yet. The delay will not affect the vaccine efficacy. The CDC states the second dose may be administered as late as six weeks after the first dose. This week’s cancellations will not change weekly regional vaccine allocations.
