By the Numbers: COVID-19 Vaccinations in the U.S.


Which vaccines are approved? Which are next?

Three vaccines have received emergency use authorization (EUA) in the U.S. Several more are on the way.

(Note: Click on each of the vaccines for an article about how each vaccine works.)


  • Pfizer: 95% effective. 2 doses, 3 weeks apart.
  • Moderna: 94.5% effective, 2 doses, 4 weeks apart. 
  • Johnson & Johnson: 72% effective in preventing moderate-to-severe disease. 100% effective in preventing hospitalization and death. 1 dose.

Likely Next

According to the New York Times Vaccine Tracker, there are 23 total vaccines in Phase III, which means they could report final (or close to final) data soon.

Frequently Asked Questions

We know many of you are eager to get vaccinated. However, because almost the entire process is in the hands of our state health departments and the CDC, it is challenging to predict when we will get vaccines and how many we will have at any time. We are committed to providing ongoing updates as more information becomes available. 

For PartnerMD Members


Will concierge practices like PartnerMD get access to the vaccines before other providers?

No. Concierge practices, including PartnerMD, do not have priority access to receive vaccines before any other medical provider. We have done everything we need to do to eventually receive vaccines, but the rest of the process is dependent on our state health departments and the CDC. They decide:

  • Which medical providers receive vaccines
  • When medical providers can be allocated a supply of vaccines
  • How many doses of a vaccine medical providers will receive
  • Whom medical providers can give the vaccine first

Now that we’ve done our part (applying to receive vaccines), it’s a waiting game. Every other primary care practice, concierge or not, is in the same boat.

When will PartnerMD get vaccines?

We are actively waiting for updates from the state in each of our locations on when vaccine supplies will be available to our office. It may be that vaccines are available outside our offices sooner.

In either case, we will update you as we learn information about opportunities for you to get vaccinated as soon as possible, whether that is at one of our locations or elsewhere.

Who is deciding where vaccines go?

The health departments in each state are working with the CDC to allocate and distribute vaccines at their discretion. All medical providers, including concierge practices, are dependent on their decisions. 

Which vaccine will PartnerMD get?

We don’t expect to have a choice. We will be prepared for any vaccine that is approved, but the state health departments will likely allocate based only on what is available. 

Will PartnerMD get enough doses for all members?

Like the timing for vaccine distribution, how many doses we receive is not in our control. This will be mandated by the CDC and the state health departments.

Who can get vaccinated at PartnerMD?

Like all providers, PartnerMD will receive guidance from the CDC and state health departments on who we can vaccinate first.

We expect these instructions will align with the how initial roll-out is proceeding, with the most at-risk population (the elderly, chronic health conditions, etc.) first.

Depending on your age and other risk factors, you may be eligible to get your vaccination from another provider before PartnerMD even has the vaccine available. Each state will communicate more info as they receive more vaccines.

When PartnerMD does have vaccines, how will I know when I am eligible for one?

As we receive information from our state health departments about whom we can vaccinate, we will communicate that information via our website, email, and social media. We expect it will be instructions in line with their recommendations (75+ and older first, then 65+ and older, and so on).

Where can I get more information about COVID-19 testing, office visits, and telehealth appointments at PartnerMD?

About Vaccine Science

How are the vaccines administered? 

All three vaccines (Moderna, Pfizer, Johnson & Johnson) require the patient to receive a shot in the arm.

The Pfizer vaccine requires two doses three weeks apart, and the Moderna vaccine requires two doses four weeks apart. Johnson & Johnson is a single-dose vaccine.  

How long until the vaccines are effective? 

A typical vaccine takes about two weeks to be fully effective in our bodies. That's why, for example, it's often recommended to wait until October to get a flu vaccine, so you have the most potent vaccine working during the most critical time.

How long will immunity last from the vaccines? 

We don't know yet. That will take a long time to definitively figure out. All vaccine trials will continue to monitor their participants over the coming months and years to establish that. 

What are the side effects of the vaccines? 

The approved vaccines have not indicated any significant safety concerns to date. 

All three vaccines report similar side effects:  pain at the injection site, fatigue, cold/flu-like symptoms, and fever. Side effects usually subside within a day or two and, for the Pfizer and Moderna vaccines, may be stronger after the second dose. 

What is an mRNA vaccine? 

Vaccines developed using messenger RNA technology differ from traditional vaccines.

Traditional vaccines rely on the body's natural defense reactions when a small quantity of live or dead virus is introduced to the body.

A vaccine made from mRNA uses a snippet of DNA from the virus to elicit a similar defense reaction in the body.
