As the District launched its new system to register for a COVID-19 vaccine this week, it also announced major changes to help ensure more doses go to people who actually live there. ”The essential worker burden for vaccinations in the District is disproportionately high [compared] to any other jurisdiction,” said Dr. LaQuandra Nesbitt, head of DC Health. Going forward, the District will prioritize 90% of its appointments for eligible residents only. In its new registration portal, D.C. said essential workers should bring verification like a work ID badge, letter from employer or paystub. ”One of the ways that we have to ensure that we are not vaccinating residents from other jurisdictions who don’t actually have an essential job in the District of Columbia is to ask for some type of proof for that,” Nesbitt said.
