More than 1.7 million doses of the coronavirus vaccine have been administered in D.C., Maryland and Virginia. But in all three jurisdictions, the rollout has been bumpy, with reports of shipping mishaps, canceled appointments and confusing sign-up systems.

In Maryland and Virginia, some local jurisdictions have held back on providing first doses of the vaccine, fearing potential supply shortages. In the District, health officials have been working to address racial disparities regarding who has been able to sign up for new vaccination appointments.

The Washington Post’s Julie Zauzmer, Rebecca Tan, Antonio Olivo and Angela Fritz answered questions about the vaccine rollout, the future of mask-wearing and efforts underway to vaccinate prioritized populations around the Washington region on Wednesday, Feb. 17.

Zauzmer covers the D.C. government, reporting on measures to curtail the spread of the virus. Tan reports on vaccine distribution in Maryland and has written about patient care in nursing homes around the Washington region. Olivo covers Virginia government, politics and the state’s response to the pandemic.

Fritz is the deputy editor on the General Assignment news desk, where she edits and writes The Post’s Coronavirus Updates newsletter.

An update: A day after this chat, the District government significantly altered its plans for which people with medical conditions will be prioritized for vaccinations, which means some of the chat answers are out of date. The city will no longer limit priority to people over 50; instead, starting March 1, anyone 16 or over with a qualifying medical condition can register for a vaccine. D.C. also changed its list of qualifying medical conditions, removing smoking and having a body mass index over 25 (though BMI over 30 still qualifies). The updated list of qualifying conditions is here. And you can read all about the up-to-date rules here.
