Across the D.C. area, officials are rolling out the coronavirus vaccines in phases. In general, vaccines are still limited to those in the health care field and some other front-line workers, as well as the area’s oldest residents. However, there are differences across each jurisdiction.

Virginia

Virginia is currently in its version of Phase 1b of the vaccine rollout. This includes front line essential workers, such as police and firefighters, teachers and grocery store workers; people 65 and older, people 16-64 with high-risk medical conditions.

Virginia health officials announced the launch of a new statewide pre-registration system starting Feb. 16. (Fairfax County, however will not be participating in the statewide system.)

However, county health department clinics may have specific steps for registering for appointments and, given the low supply, may be prioritizing certain populations only:

In addition to health department clinics, some CVS pharmacies in Virginia are also offering the vaccine.

Maryland

In Maryland, the vaccination rollout statewide is now in Phase 2a, which includes residents 60 and older, as well as teachers and other front-line essential workers.

You can see the full list of people in Maryland’s Phase 2a . However, remember, your local health department may only be prioritizing certain groups.

Maryland has a . These sites include clinics run by local health departments, as well as sites run by hospital and retail pharmacies, such as Giant and Safeway. Be warned, however, that most sites are being hit with heavy demand and you might not be able to find an open appointment right away.

The state is also planning 12 mass vaccination sites across Maryland. Six sites are already open. . In the D.C. area, there is mass-vaccine site already up and running at Six Flags in Prince George’s County. Another mass vaccination site is set for the Germantown campus of Montgomery College in Montgomery County.

To get vaccinated at a clinic run by your local health department, you must pre-register. See links below to Maryland health departments in the D.C. area.

It’s also important when you receive a link to make an appointment, that you don’t share that with others or post it online in a Facebook group or Listserv. Officials say that results in ineligible people making appointments and gums up the works.

DC

In D.C., if you鈥檙e over 65 you can sign up for a shot by calling 855-363-0333 or using D.C.鈥檚 . Here’s where you can make an

Around the country and in the D.C. area, the initial rollout has been shaky. The No. 1 problem around the country is limited supply, even as demand for the shots has surged. Locally, the rollout has led to frustration and confusion about how to sign up for shots, eligibility rules and tech problems, as well as concerns about equal access to the shots.

Despite the confusion, shots are getting into arms, slowly but surely. Track vaccinations across D.C., Maryland and Virginia on 草莓传媒’s vaccination tracker.

Local officials are hopeful more supply is coming.

President Joe Biden has set a goal of 100 million shots in his first 100 days in office 鈥� a goal that experts say the U.S. is on track to exceed.

In addition, the Biden administration has secured more doses 鈥� a total of 600 million doses through the end of July. That’s enough doses to inoculate 300 million Americans, since the vaccines purchased required two shots.

The pace of vaccinations could increase even more if a third vaccine from Johnson & Johnson receives authorization from the Food and Drug Administration.

There are currently two COVID-19 vaccines in circulation. One is made by Pfizer-BioNTech and the other is made by Moderna. Both require two shots.

For Pfizer, the booster shot is needed three weeks after your first shot. For Moderna鈥檚, it鈥檚 four weeks.

The Pfizer requires deep-freeze storage.

The Johnson & Johnson vaccine is unique because it only requires one shot. The FDA has scheduled a meeting Feb. 26, when advisers will review the data and decide whether to green-light the vaccine option.

Another vaccine option, made by the pharmaceutical company AstraZeneca has been authorized in other parts of the world but not in the U.S.

Dr. Anthony Fauci, the nation’s top infectious diseases doctor said he expects the pace of vaccinations to pick up over the next few months and predicted it would be “open season” around April, meaning anyone 鈥� not just those in high-risk groups 鈥� could sign up for the shots.

Pfizer and Moderna are reporting preliminary results from late-stage trials that show their vaccines are almost 95% effective.

AstraZeneca says its vaccine is up to 90% effective.

Percentages in vaccine efficacy and vaccine effectiveness describes “the proportionate reduction in disease among the vaccinated group. So a VE of 90% indicates a 90% reduction in disease occurrence among the vaccinated group, or a 90% reduction from the number of cases you would expect if they have not been vaccinated,” .

There’s a formula for it:

“Vaccine efficacy/effectiveness (VE) is measured by calculating the risk of disease among vaccinated and unvaccinated persons and determining the percentage reduction in risk of disease among vaccinated persons relative to unvaccinated persons. The greater the percentage reduction of illness in the vaccinated group, the greater the vaccine efficacy/effectiveness.

The basic formula is written as:

In the first formula, the numerator (risk among unvaccinated 鈭� risk among vaccinated) is sometimes called the risk difference or excess risk.”

The vaccines differ in doses and distribution requirements.

A half-dose of AstraZeneca‘s vaccine followed by a full dose at least one month later was 90% effective.

Both Pfizer and Moderna‘s vaccines require two shots. For Pfizer, the booster shot is needed three weeks after your first shot. For Moderna’s, it’s four weeks.

AstraZeneca’s vaccine doesn鈥檛 need to be stored at ultracold temperatures, making it easier to distribute, especially in developing countries. It can be transported under 鈥渘ormal refrigerated conditions鈥� of 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit).

Pfizer, on the other hand, plans to distribute its vaccine using specially designed 鈥渢hermal shippers鈥� that use dry ice to maintain temperatures of minus-70 degrees Celsius (minus-94 degrees Fahrenheit).

AstraZeneca’s vaccine uses a weakened version of a common cold virus that is combined with genetic material for the characteristic spike protein of the virus that causes COVID-19. After vaccination, the spike protein primes the immune system to attack the virus if it later infects the body. Pfizer and Moderna’s vaccines also teach the immune system to recognize coronavirus, through .

Nope.

Dr. Anthony Fauci, the top disease expert in the U.S., told CBS that for there to be herd immunity requires that a majority of the country be vaccinated.

鈥淚f you have a highly efficacious vaccine, and only a relatively small 40, 50% of the people get vaccinated, you鈥檙e not going to get the herd immunity you need,鈥� Fauci said. 鈥淲hat we do need is we need to get as many people as possible vaccinated.鈥�

The CDC cautions that experts “do not know what percentage of people would need to get vaccinated to achieve herd immunity.”

What exactly is herd immunity?

Per the : “Herd immunity is a term used to describe when enough people have protection 鈥� either from previous infection or vaccination 鈥� that it is unlikely a virus or bacteria can spread and cause disease. As a result, everyone within the community is protected even if some people don鈥檛 have any protection themselves. The percentage of people who need to have protection in order to achieve herd immunity varies by disease.”

Stay safe: Wear a mask, wash your hands, use hand sanitizer, reduce your risk of exposure, check for symptoms and get tested.
