Loudoun Now Loudoun County will switch to using the Virginia Department of Health’s statewide COVID-19 vaccine pre-registration system at 5 p.m. Friday, Feb. 12, following direction from the state that came earlier that day. In launching the new statewide system, the Virginia Department of Health directed all local health districts to close their pre-registration forms and surveys at 5 p.m. Friday to allow for existing registration data to be transferred to the new system. Loudoun County residents will not be able to register for COVID-19 vaccine for a few days. People who already submitted a pre-screening survey through the Loudoun County Health Department need not worry: those surveys will be automatically added to the new statewide system. There is no need for those people to complete a new survey when the state system goes live next week, according to the county.
