Many of you have been asking about Covid vaccinations.  Unfortunately, we still have little information beyond what we are learning from the news.  Currently, residents of long-term care facilities and medical personnel with direct patient contact are eligible to be vaccinated, but local health departments as yet have insufficient supply to cover this group. In the coming months, once all health care workers have been immunized, additional people will be permitted to get the vaccine. The next group will include people over age 75, plus such critical personnel as teachers, police, firefighters, etc.  Following them, people age 65 and over and those with underlying diseases which predispose to increased risk from Covid, will become eligible. And finally, vaccine will be made available to the general public.  Depending on your age, occupation and health status, it may be several months before you qualify. 


Our office has registered to be providers of the Moderna vaccine, but we have learned from the DC public health department that we will not receive shipments until vaccinations are approved for the general public – likely late in the spring.  Each health department in Virginia, Maryland and Washington DC has developed its own guidelines for distribution.  In Washington, the website: will allow you to enter your demographics and determine eligibility for vaccination. Once you qualify, you will be offered an appointment, but at this point, only health care workers are being scheduled.  As new vaccines are approved and manufacturing scaled up, plans will undoubtedly change, and we will update our site as we learn more.  Please keep an eye on the news and check back here for new information.  In the meantime, stay safe and wear a mask.
